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&#8217;s rotor, which mills the binder-covered material to depth and mixes it with water in the same forward pass.<\/p>\n<p>The key operational advantage of the DCW 2.2 over conventional &#8220;bag-spread&#8221; 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<p>El sistema combinado de tractor \u00fanico DCW 2.2 (delantero) + THOR ST (trasero) elimina la necesidad de una pasada separada de aplicaci\u00f3n de ligante antes de la m\u00e1quina de estabilizaci\u00f3n, lo que reduce el n\u00famero total de movilizaciones de equipos, la duraci\u00f3n total del proyecto y el coste total de construcci\u00f3n de los proyectos de rehabilitaci\u00f3n de carreteras rurales.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-482\" src=\"https:\/\/rock-crusher-tractor.com\/wp-content\/uploads\/2026\/05\/Binder-Spreader-Application-1.webp\" alt=\"Aplicaci\u00f3n del esparcidor de aglutinante 1\" width=\"1536\" height=\"1024\" srcset=\"https:\/\/rock-crusher-tractor.com\/wp-content\/uploads\/2026\/05\/Binder-Spreader-Application-1.webp 1536w, https:\/\/rock-crusher-tractor.com\/wp-content\/uploads\/2026\/05\/Binder-Spreader-Application-1-1280x853.webp 1280w, https:\/\/rock-crusher-tractor.com\/wp-content\/uploads\/2026\/05\/Binder-Spreader-Application-1-980x653.webp 980w, https:\/\/rock-crusher-tractor.com\/wp-content\/uploads\/2026\/05\/Binder-Spreader-Application-1-480x320.webp 480w\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) and (max-width: 980px) 980px, (min-width: 981px) and (max-width: 1280px) 1280px, (min-width: 1281px) 1536px, 100vw\" \/><\/p>\n<p><!-- SECTION 2 \u2014 SPECIFICATIONS --><\/p>\n<div style=\"background: #f7f7f7;

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><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-483 aligncenter\" src=\"https:\/\/rock-crusher-tractor.com\/wp-content\/uploads\/2026\/05\/Binder-Spreader-1.webp\" alt=\"Esparcidor de aglutinante 1\" width=\"600\" height=\"600\" srcset=\"https:\/\/rock-crusher-tractor.com\/wp-content\/uploads\/2026\/05\/Binder-Spreader-1.webp 600w, https:\/\/rock-crusher-tractor.com\/wp-content\/uploads\/2026\/05\/Binder-Spreader-1-480x480.webp 480w\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) 600px, 100vw\" \/><\/p>\n<p>&nbsp;<\/p>\n<h3>Rodillo doble: selecci\u00f3n de ancho de 1 m o 2 m.<\/h3>\n<p style=\"margin-bottom: 16px;\">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&#8217;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<h3>Sistema de control electr\u00f3nico \u2014 Pantalla de cabina<\/h3>\n<p style=\"margin-bottom: 16px;\">El DCW 2.2 incluye su propio sistema de control electr\u00f3nico con una pantalla instalada en la cabina del tractor. El operador supervisa y ajusta la tasa de aplicaci\u00f3n del ligante desde la pantalla de la cabina sin detener la m\u00e1quina, compensando las variaciones de velocidad de avance para mantener la dosis objetivo de ligante por metro cuadrado. El sistema electr\u00f3nico registra los datos reales de aplicaci\u00f3n, proporcionando un registro del proyecto con la cantidad y cobertura del ligante para la documentaci\u00f3n de control de calidad. Esto representa una ventaja significativa sobre los m\u00e9todos de esparcimiento manual para proyectos viales financiados por el gobierno que requieren registros documentados de control de calidad.<\/p>\n<h3>Montaje frontal: funcionamiento combinado de una sola pasada.<\/h3>\n<p>The DCW 2.2 mounts at the tractor&#8217;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&#8217;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<p><!-- SECTION 4 \u2014 SYSTEM POSITION --><\/p>\n<div style=\"background: #f0f5f9; border: 1px solid #dce8f0; padding: 24px 3% 3%; border-radius: 6px; margin-top: 40px; box-sizing: border-box;\">\n<h2 style=\"font-size: clamp(18px,2.5vw+10px,26px); background: linear-gradient(to right,#1a1a1a 0%,#2e2e2e 72%,#c86000 100%); color: #fff; padding: 14px 20px; border-radius: 4px; margin: 0 0 20px 0; line-height: 1.3;\">DCW 2.2 en el flujo de trabajo completo de estabilizaci\u00f3n de suelos<\/h2>\n<p style=\"margin-bottom: 20px;\">El DCW 2.2 es el componente de distribuci\u00f3n del aglutinante en el sistema de estabilizaci\u00f3n de suelos de cuatro m\u00e1quinas.

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&#8217;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<div style=\"background: #fafafa; border-radius: 4px; padding: 15px 18px; border-left: 3px solid #ddd;\">\n<p style=\"font-weight: bold; color: #1a1a1a; margin: 0 0 6px 0;\">\u00bfQu\u00e9 tractor se necesita para transportar simult\u00e1neamente tanto el DCW 2.2 como el THOR ST?<\/p>\n<p style=\"margin: 0; color: #555; font-size: clamp(13px,1.4vw+8px,15px);\">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&#8217;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<div style=\"background: #fff; border-radius: 4px; padding: 15px 18px; border-left: 3px solid #f07c00;\">\n<p style=\"font-weight: bold; color: #1a1a1a; margin: 0 0 6px 0;\">What is the &#8220;mandatory weight&#8221; of 1,300 Kg?<\/p>\n<p style=\"margin: 0; color: #555; font-size: clamp(13px,1.4vw+8px,15px);\">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&#8217;s own weight (hopper weight + machine weight) and any additional front ballast weights on the tractor. Confirm the tractor&#8217;s specific front axle load with both implements attached before commissioning the combined system.<\/p>\n<\/div>\n<div style=\"background: #fafafa; border-radius: 4px; padding: 15px 18px; border-left: 3px solid #ddd;\">\n<p style=\"font-weight: bold; color: #1a1a1a; margin: 0 0 6px 0;\">\u00bfC\u00f3mo se calibra la velocidad de aplicaci\u00f3n del aglutinante electr\u00f3nico?<\/p>\n<p style=\"margin: 0; color: #555; font-size: clamp(13px,1.4vw+8px,15px);\">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&#8217;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<div style=\"background: #fff; border-radius: 4px; padding: 15px 18px; border-left: 3px solid #f07c00;\">\n<p style=\"font-weight: bold; color: #1a1a1a; margin: 0 0 6px 0;\">\u00bfCu\u00e1les son las dosis t\u00edpicas de aplicaci\u00f3n de aglutinante para la estabilizaci\u00f3n de carreteras rurales en Corea?<\/p>\n<p style=\"margin: 0; color: #555; font-size: clamp(13px,1.4vw+8px,15px);\">Las dosis de aplicaci\u00f3n del ligante deben determinarse mediante an\u00e1lisis de laboratorio del material vial espec\u00edfico que se va a estabilizar; no existe una dosis universal. A modo de gu\u00eda general (no sustituye a las pruebas de laboratorio): la estabilizaci\u00f3n con cemento de materiales granulares de base vial t\u00edpicos de las zonas monta\u00f1osas de Corea generalmente requiere de 4 a 81 TP5T de cemento por peso seco del suelo (aproximadamente de 7 a 15 kg\/m\u00b2 a 100 mm de profundidad, seg\u00fan la densidad del suelo); la estabilizaci\u00f3n con cal de suelos arcillosos en las zonas costeras de Corea generalmente requiere de 3 a 61 TP5T de cal por peso seco. La dosis de aplicaci\u00f3n definitiva para cualquier proyecto debe confirmarse mediante pruebas de compactaci\u00f3n Proctor y UCS de mezclas de suelo + ligante espec\u00edficas del sitio antes del inicio del proyecto.

In addition, the THOR ST&#8217;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&#8217;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<div style=\"background: #fafafa; border-radius: 4px; padding: 15px 18px; border-left: 3px solid #ddd;\">\n<p style=\"font-weight: bold; color: #1a1a1a; margin: 0 0 6px 0;\">\u00bfQu\u00e9 mantenimiento requiere el DCW 2.2 despu\u00e9s de cada proyecto?<\/p>\n<p style=\"margin: 0; color: #555; font-size: clamp(13px,1.4vw+8px,15px);\">Despu\u00e9s de cada proyecto: vac\u00ede completamente la tolva; la cal o el cemento residual absorben la humedad y se endurecen, obstruyendo el mecanismo de rodillos. Limpie a fondo el interior de la tolva, los rodillos y el mecanismo de distribuci\u00f3n con aire comprimido y un cepillo; no utilice agua en los componentes internos (cemento + agua = reacci\u00f3n de fraguado). Inspeccione las superficies de los rodillos para detectar desgaste y dep\u00f3sitos. Compruebe la pantalla de control electr\u00f3nico y las conexiones de los cables. Lubrique todos los puntos de engrase seg\u00fan el programa de mantenimiento. El problema de mantenimiento m\u00e1s com\u00fan en los equipos de esparcimiento es el endurecimiento residual del aglutinante en el mecanismo de distribuci\u00f3n debido a una limpieza posterior al uso incompleta; evite esto limpiando a fondo al final de cada jornada laboral y antes de cualquier per\u00edodo de almacenamiento prolongado.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<p><!-- CUSTOMER REVIEWS --><\/p>\n<div style=\"margin-top: 40px;\">\n<h2 style=\"font-size: clamp(18px,2.5vw+10px,26px); background: linear-gradient(to right,#1a1a1a 0%,#2e2e2e 72%,#c86000 100%); color: #fff; padding: 14px 20px; border-radius: 4px; margin: 0 0 20px 0; line-height: 1.3;\">Opiniones de los clientes<\/h2>\n<div style=\"display: flex; flex-direction: column; gap: 12px;\">\n<div style=\"border: 1px solid #e8e8e8; border-radius: 4px; padding: 18px; background: #fff;\">\n<p style=\"font-weight: bold; color: #1a1a1a; margin: 0 0 2px 0;\">Yoo Sung-jin \u2014 Contratista de caminos rurales, Jecheon, Chungcheong del Norte (2025)<\/p>\n<p style=\"color: #f07c00; margin: 0 0 10px 0; font-size: 0.88em;\">\u2605\u2605\u2605\u2605\u2605<\/p>\n<p style=\"color: #444; margin: 0; font-size: clamp(13px,1.4vw+8px,15px);\">&#8220;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.&#8221;<\/p>\n<\/div>\n<div style=\"border: 1px solid #e8e8e8; border-radius: 4px; padding: 18px; background: #fafafa;\">\n<p style=\"font-weight: bold; color: #1a1a1a; margin: 0 0 2px 0;\">Kim Hyeon-taek \u2014 Contratista de carreteras, Wonju, Gangwon-do (2024\u20132025)<\/p>\n<p style=\"color: #f07c00; margin: 0 0 10px 0; font-size: 0.88em;\">\u2605\u2605\u2605\u2605\u2605<\/p>\n<p style=\"color: #444; margin: 0; font-size: clamp(13px,1.4vw+8px,15px);\">&#8220;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.&#8221;<\/p>\n<\/div>\n<div style=\"border: 1px solid #e8e8e8; border-radius: 4px; padding: 18px; background: #fff;\">\n<p style=\"font-weight: bold; color: #1a1a1a; margin: 0 0 2px 0;\">Choi Wan-su - Contratista de ingenier\u00eda civil, Naju, Jeolla del Sur (2025)<\/p>\n<p style=\"color: #f07c00; margin: 0 0 10px 0; font-size: 0.88em;\">\u2605\u2605\u2605\u2605\u2605<\/p>\n<p style=\"color: #444; margin: 0; font-size: clamp(13px,1.4vw+8px,15px);\">&#8220;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.

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.&#8221;<\/p>\n<\/div>\n<div style=\"border: 1px solid #e8e8e8; border-radius: 4px; padding: 18px; background: #fff;\">\n<p style=\"font-weight: bold; color: #1a1a1a; margin: 0 0 2px 0;\">Jeong Hyun-jo \u2014 Ingeniero de Caminos del Condado, Boryeong-si, Chungcheong del Sur (2025)<\/p>\n<p style=\"color: #f07c00; margin: 0 0 10px 0; font-size: 0.88em;\">\u2605\u2605\u2605\u2605\u2605<\/p>\n<p style=\"color: #444; margin: 0; font-size: clamp(13px,1.4vw+8px,15px);\">&#8220;As the supervising engineer on the Boryeong stabilization project, the DCW 2.2&#8217;s electronic application records were what we needed for the quality assurance documentation.

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.
