DCW 2.2 \u2014 \u00c9pandeur de chaux\/ciment de pr\u00e9cision pour la stabilisation des sols en un seul passage<\/h2>\n

L'\u00e9pandeur Watanabe DCW 2.2 est un \u00e9pandeur frontal pour liants chaux et ciment, con\u00e7u pour fonctionner en combinaison directe avec l'\u00e9pandeur arri\u00e8re. Stabilisateur de sol THOR ST<\/a> for single-pass soil stabilization of rural roads and agricultural infrastructure. Mounted at the front of the CVT tractor, the DCW 2.2 distributes lime or cement binder uniformly across the road surface at a precisely controlled application rate \u2014 immediately ahead of the THOR ST’s rotor, which mills the binder-covered material to depth and mixes it with water in the same forward pass.<\/p>\n

The key operational advantage of the DCW 2.2 over conventional “bag-spread” or broadcast truck spreading methods is precision and uniformity. The binder application rate is controlled electronically from a display installed in the tractor cab \u2014 the operator adjusts the delivery rate based on forward speed to maintain the target kg\/m\u00b2 binder dosage regardless of speed variation. Two internal rollers provide selectable distribution width: 2-meter width for the standard road treatment pass, or two independent 1-meter sections for partial-width treatment on roads where one lane can remain open during construction.<\/p>\n

Le syst\u00e8me combin\u00e9 DCW 2.2 (avant) + THOR ST (arri\u00e8re) \u00e0 un seul tracteur \u00e9limine le besoin d'un passage s\u00e9par\u00e9 d'\u00e9pandage de liant avant la machine de stabilisation, r\u00e9duisant ainsi le nombre total de mobilisations d'\u00e9quipements, la dur\u00e9e totale du projet et le co\u00fbt total de construction des projets de r\u00e9habilitation des routes rurales.<\/p>\n

Fonctionnement du DCW 2.2 \u2014 Deux rouleaux internes et contr\u00f4le \u00e9lectronique de la vitesse<\/h2>\n

The DCW 2.2’s binder hopper holds the powdered lime or cement that will be applied to the road surface. Two internal rotating rollers drive the binder from the hopper through the distribution mechanism and onto the road surface at the controlled application rate. The key advantage of the roller-drive distribution system over gravity-fed or auger-feed alternatives is its ability to deliver a consistent volumetric flow rate \u2014 providing uniform ground coverage regardless of small variations in binder particle size or bulk density.<\/p>\n

 <\/p>\n

Rouleau double \u2014 Choix de largeur\u00a0: 1\u00a0m ou 2\u00a0m<\/h3>\n

The two internal rollers are independently controlled. When both rollers are active, binder is distributed across the full 2,140 mm working width \u2014 matching the THOR ST’s milling width for a fully uniform binder coverage before the stabilizer pass. When only one roller is active, binder is distributed across a 1-meter section only \u2014 allowing the operator to treat one lane while leaving the adjacent lane undisturbed. This is particularly useful on road sections where one-lane traffic must be maintained during construction, or where a partial-width re-treatment of a specific lane or shoulder section is needed without treating the full road width.<\/p>\n

Montage frontal \u2014 Fonctionnement combin\u00e9 en un seul passage<\/h3>\n

The DCW 2.2 mounts at the tractor’s front three-point hitch \u2014 the only configuration that allows the binder to be distributed immediately ahead of the rear-mounted THOR ST stabilizer’s rotor in the same forward pass. The separation distance between the DCW 2.2 application point and the THOR ST rotor is the tractor wheelbase \u2014 typically 3\u20134 meters. This ensures the binder is spread uniformly before the rotor mixes it, but is not exposed to wind or rain disturbance for an extended period before incorporation. The single-tractor, front-plus-rear configuration is the most efficient soil stabilization setup available \u2014 one operator, one tractor pass, complete binder distribution and soil milling in one coordinated operation.<\/p>\n<\/div>\n

\u25a0 Polyvalence d'application \u2014 1 m ou 2 m<\/p>\n

Deux rouleaux internes ind\u00e9pendants permettent de basculer instantan\u00e9ment entre une distribution de liant sur 2 m\u00e8tres (largeur de travail totale) et sur 1 m\u00e8tre (voie unique). Sur les tron\u00e7ons de routes rurales cor\u00e9ennes o\u00f9 la circulation doit \u00eatre maintenue dans un seul sens pendant les travaux, le mode 1 m permet de traiter une voie \u00e0 la fois sans fermeture compl\u00e8te de la route, r\u00e9duisant ainsi les perturbations pour les riverains et la responsabilit\u00e9 de l'entrepreneur en cas d'interruption d'acc\u00e8s.<\/p>\n<\/div>\n

La suppression d'un passage de couverture compl\u00e8te dans le processus r\u00e9duit le nombre total d'heures d'utilisation des engins, la consommation totale de carburant et le co\u00fbt total du projet, un avantage particuli\u00e8rement significatif sur les longs tron\u00e7ons routiers o\u00f9 la mobilisation et la couverture des passages repr\u00e9sentent les principaux facteurs de co\u00fbt.<\/p>\n<\/div>\n

\u25a0 Efficacit\u00e9 et \u00e9conomie par rapport aux m\u00e9thodes manuelles<\/p>\n

The conventional “bag-spread” method \u2014 manually placing bags of lime or cement and spreading with a brush rake \u2014 is both labour-intensive and inherently non-uniform. Uneven binder distribution produces uneven stabilization strength, which creates weak zones in the completed road base that fail at accelerated rates under traffic. The DCW 2.2’s mechanized uniform distribution eliminates this variability and reduces labour requirements to zero for the binder distribution step.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

Applications \u2014 Projets cor\u00e9ens d'am\u00e9lioration des routes rurales et des sols<\/h2>\n

R\u00e9habilitation des routes rurales par stabilisation \u00e0 la chaux ou au ciment<\/h3>\n

L'application la plus courante du DCW 2.2 en Cor\u00e9e est le dosage de chaux ou de ciment pour la stabilisation in situ des routes d\u00e9grad\u00e9es. Le dosage est d\u00e9termin\u00e9 par la classification du sol du mat\u00e9riau routier existant (essais en laboratoire avant la construction) et la r\u00e9sistance \u00e0 la compression non confin\u00e9e (RCNC) cible pour la base stabilis\u00e9e. Les dosages de ciment pour les mat\u00e9riaux granulaires typiques des routes rurales cor\u00e9ennes varient d'environ 4 \u00e0 81 t\/5 (poids sec)\u00a0; les dosages de chaux pour les sols argileux varient de 3 \u00e0 61 t\/5. Le DCW 2.2 applique ces dosages uniform\u00e9ment \u00e0 vitesse de travail, une capacit\u00e9 que l'\u00e9pandage manuel ne peut reproduire de mani\u00e8re fiable sur toute la longueur de la route.<\/p>\n

Am\u00e9lioration de la route d'acc\u00e8s \u00e0 Mountain Farm<\/h3>\n

On mountain farm access roads in Gangwon-do and the Gyeongsang highlands, lime or cement stabilization converts compacted earth tracks into all-weather structural surfaces capable of supporting farm trucks and agricultural machinery year-round. The DCW 2.2’s 1m\/2m width flexibility is particularly valuable on narrow mountain access roads where the full 2,140 mm working width of the 2m setting may exceed the usable road surface width on the narrowest sections.<\/p>\n

Pour les routes internes des entreprises de plantation, les voies de desserte des zones industrielles et les aires de stockage des centres logistiques o\u00f9 le mat\u00e9riau de base existant se pr\u00eate \u00e0 la stabilisation, la combinaison DCW 2.2 + THOR ST offre la solution la plus \u00e9conomique et la plus rapide pour passer d'une surface d\u00e9grad\u00e9e \u00e0 une assise routi\u00e8re stabilis\u00e9e. Ces projets ne n\u00e9cessitent g\u00e9n\u00e9ralement pas d'approbation technique formelle pour la m\u00e9thode de construction, ce qui simplifie les proc\u00e9dures d'approvisionnement et de mobilisation.<\/p>\n

\"Certifications<\/div>\n
The DCW 2.2 is part of Watanabe’s complete soil stabilization system range, developed and manufactured at the company’s Castro, Paran\u00e1, Brazil facility since 1970. Watanabe’s experience in soil stabilization equipment covers the full process from binder distribution to rotor milling \u2014 the DCW 2.2 and THOR ST reflect the integration of these two steps into a coordinated single-operator, single-tractor workflow that has been validated over years of operational experience in Brazilian rural road rehabilitation programs.<\/span><\/div>\n<\/div>\n

Why Brazil’s Rural Road Experience Applies to Korea<\/h3>\n

Brazil operates one of the world’s largest networks of unsurfaced rural roads \u2014 several million kilometers of agricultural access, farm-to-market, and village connector roads across conditions ranging from tropical clay through granite highlands and coastal sandy soils. The DCW 2.2 was designed and refined in this environment \u2014 precisely the conditions that Korean \ub18d\uc5b4\ucd0c\ub3c4\ub85c rehabilitation projects present. The operational parameters (binder types, application rates, working widths), equipment robustness requirements, and logistics conditions that shaped the DCW 2.2’s design directly parallel Korean rural road project conditions.<\/p>\n

Foire aux questions \u2014 DCW 2.2<\/h2>\n
\n
\n

Le DCW 2.2 peut-il \u00eatre utilis\u00e9 sans le stabilisateur de sol THOR ST\u00a0?<\/p>\n

Yes \u2014 the DCW 2.2 can operate as a standalone front-mounted binder spreader independently of the THOR ST. In this configuration, it distributes lime or cement as a pre-spreading pass before a stabilization machine (any brand) makes its mixing pass separately. However, the full operational efficiency of the DCW 2.2 is only realized when it works simultaneously with the rear-mounted THOR ST on the same tractor \u2014 the single-pass binder distribution + milling combination is the system’s primary design purpose. Using the DCW 2.2 standalone adds a separate spreading pass to the project workflow, which is more efficient than manual spreading but less efficient than the combined single-pass operation.<\/p>\n<\/div>\n

\n

Quel tracteur est n\u00e9cessaire pour transporter simultan\u00e9ment le DCW 2.2 et le THOR ST ?<\/p>\n

The combined configuration requires: (1) CVT tractor (mandatory for THOR ST operating speed range); (2) minimum 250 CV power (THOR ST PTO requirement); (3) front three-point hitch with minimum 1,300 Kg lifting capacity for DCW 2.2 at the front; (4) rear three-point hitch or drawbar for THOR ST at the rear; (5) adequate tractor ballasting for front-rear weight distribution with both implements attached. Total system weight on the tractor is significant \u2014 confirm with your tractor manufacturer or dealer that the front hitch capacity and tractor frame loading are within the tractor’s rated specification for combined front and rear implement attachment. European CVT tractors in the 250\u2013350 CV range (Fendt, New Holland, CLAAS, John Deere IVT) typically accommodate this configuration.<\/p>\n<\/div>\n

\n

What is the “mandatory weight” of 1,300 Kg?<\/p>\n

The 1,300 Kg mandatory weight is the minimum front-axle load required when the DCW 2.2 is front-mounted and loaded with binder. This front weight is necessary to maintain tractor steering control and prevent front-axle lift when the heavy rear-mounted THOR ST (5,300 Kg) is also attached and working. The 1,300 Kg front ballast is typically achieved by a combination of the DCW 2.2’s own weight (hopper weight + machine weight) and any additional front ballast weights on the tractor. Confirm the tractor’s specific front axle load with both implements attached before commissioning the combined system.<\/p>\n<\/div>\n

\n

Comment le d\u00e9bit d'application du liant \u00e9lectronique est-il calibr\u00e9\u00a0?<\/p>\n

The DCW 2.2 control system is calibrated during initial setup by running the spreader at a measured speed over a test area and collecting and weighing the output \u2014 the calibration factor is then entered into the cab display. Once calibrated, the system automatically adjusts the roller speed to maintain the target application rate as the tractor’s forward speed varies. A re-calibration check is recommended when changing binder type (lime vs. cement, different grades) since particle density and flow characteristics differ between binder types and can affect the relationship between roller speed and actual delivery rate.<\/p>\n<\/div>\n

\n

Quels sont les taux d'application typiques de liant pour la stabilisation des routes rurales cor\u00e9ennes\u00a0?<\/p>\n

La dose d'application d\u00e9finitive pour chaque projet doit \u00eatre confirm\u00e9e par des essais de compactage Proctor et de r\u00e9sistance \u00e0 la compression uniaxiale (UCS) sur des m\u00e9langes sol-liant sp\u00e9cifiques au site avant le d\u00e9but des travaux.

\n

Quelle est la capacit\u00e9 de la tr\u00e9mie et \u00e0 quelle fr\u00e9quence faut-il la remplir\u00a0?<\/p>\n

La capacit\u00e9 de la tr\u00e9mie du DCW 2.2 et sa fr\u00e9quence de remplissage d\u00e9pendent du taux d'application du liant et de la vitesse de travail. Veuillez nous communiquer les param\u00e8tres de votre projet (type de liant, taux d'application cible, largeur de la chauss\u00e9e et vitesse de travail) afin que nous puissions vous fournir la capacit\u00e9 de tr\u00e9mie adapt\u00e9e et l'intervalle de remplissage estim\u00e9 pour votre configuration.

Existe-t-il un risque que la poussi\u00e8re de chaux\/ciment affecte les riverains ou les cultures ?<\/p>\n

Lime and cement powder spreaders generate airborne dust during operation \u2014 a real concern for nearby residents, crops, and water bodies. The DCW 2.2 is designed to minimize dust by distributing binder at low height through the roller mechanism rather than broadcasting from height. In addition, the THOR ST’s water injection system immediately behind the DCW 2.2 introduces moisture that suppresses dust from the freshly spread binder within seconds of application. For projects near sensitive receptors (residences, orchards, water bodies), work during low-wind conditions and inform nearby residents in advance. The Korean government’s Construction Noise and Dust Management Guidelines (\uac74\uc124\uacf5\uc0ac \uc18c\uc74c\u00b7\uc9c4\ub3d9 \uad00\ub9ac\uae30\uc900) provide the regulatory framework for dust management on construction projects.<\/p>\n<\/div>\n

Quels sont les besoins de maintenance du DCW 2.2 apr\u00e8s chaque projet\u00a0?<\/p>\n

Apr\u00e8s chaque utilisation\u00a0: videz compl\u00e8tement la tr\u00e9mie. Les r\u00e9sidus de chaux ou de ciment absorbent l\u2019humidit\u00e9 et durcissent, risquant d\u2019obstruer le m\u00e9canisme de rouleaux. Nettoyez soigneusement l\u2019int\u00e9rieur de la tr\u00e9mie, les rouleaux et le syst\u00e8me de distribution \u00e0 l\u2019air comprim\u00e9 et \u00e0 la brosse. N\u2019utilisez pas d\u2019eau sur les composants internes (ciment + eau = prise). Inspectez les surfaces des rouleaux pour d\u00e9tecter toute usure ou d\u00e9p\u00f4t. V\u00e9rifiez l\u2019affichage de la commande \u00e9lectronique et les connexions des c\u00e2bles. Lubrifiez tous les points de graissage conform\u00e9ment au calendrier d\u2019entretien. Le probl\u00e8me d\u2019entretien le plus fr\u00e9quent sur les \u00e9pandeurs est le durcissement des r\u00e9sidus de liant dans le syst\u00e8me de distribution, d\u00fb \u00e0 un nettoyage incomplet apr\u00e8s utilisation. Pour \u00e9viter cela, nettoyez soigneusement \u00e0 la fin de chaque journ\u00e9e de travail et avant toute p\u00e9riode de stockage prolong\u00e9e.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

“Running the DCW 2.2 + THOR ST combined system on the Jecheon county road contract. The electronic cab control on the DCW 2.2 is genuinely useful \u2014 I can maintain the target cement dosage rate precisely even when I have to slow down for road furniture or narrow sections. The uniformity of the binder distribution compared to the bag-spread we used to do is obvious in the finished base strength results.”<\/p>\n<\/div>\n

“The 1m\/2m width switching was unexpected but very valuable in practice. On one road section in Gangwon, we had a drainage channel on one side that restricted the usable road width. 1m mode let us treat the full road in two passes \u2014 left half, then right half \u2014 without the DCW 2.2 spreading outside the road area. The THOR ST was full width both times but the binder coverage was exactly where it needed to be.”<\/p>\n<\/div>\n

\u2605\u2605\u2605\u2605\u2605<\/p>\n

“Lime stabilization on South Jeolla clay soils \u2014 the DCW 2.2 electronic control let us hit the 4.5% lime dosage rate consistently across the full project length. Previous projects using bag-spread had variable quality because manual spreading inevitably produces uneven coverage. The supervised quality control testing on this project accepted all sections on first pass.”<\/p>\n<\/div>\n

\u2605\u2605\u2605\u2605\u2605<\/p>\n

“Timber road stabilization \u2014 the DCW 2.2 + THOR ST single-pass operation means we complete a 200m forest road section per day with one tractor operator. The alternative with bag-spread would need a separate crew for spreading and a separate machine for the milling pass. The labour cost saving is significant on remote forest road projects where getting additional workers to site is difficult.”<\/p>\n<\/div>\n

\u2605\u2605\u2605\u2605\u2605<\/p>\n

“As the supervising engineer on the Boryeong stabilization project, the DCW 2.2’s electronic application records were what we needed for the quality assurance documentation. The dosage log from the cab control system showed consistent binder application rate across the full 6 km project length. This kind of verifiable quality record is increasingly required on government road contracts and the DCW 2.2 provides it automatically.”<\/p>\n<\/div>\n

\u2605\u2605\u2605\u2605\u2605<\/p>\n

“Internal plantation road stabilization \u2014 the DCW 2.2 + THOR ST system from Korea Watanabe was the right choice for our internal road network. The Korea Watanabe team provided application rate guidance before we started based on our soil type, which avoided the trial-and-error dosage adjustment that can waste binder and delay results. Maintenance advice after the first project was also practical and useful.”<\/p>\n<\/div>\n<\/div>\n<\/div>\n
