Korean geotechnical laboratories (\ud1a0\uc9c8\uc2dc\ud5d8\uc18c) are available in major cities and university-affiliated research centers. In some cases, the county agricultural technology center (\ub18d\uc5c5\uae30\uc220\uc13c\ud130) or the Korea Rural Community Corporation (\ud55c\uad6d\ub18d\uc5b4\ucd0c\uacf5\uc0ac) can facilitate soil testing for rural road projects in their program areas.

Korean projects that have been in service for 18\u201324 months post-treatment show maintenance-free performance on most reported sites. Long-term performance beyond this timeframe is consistent with the international FDR literature showing 10\u201320 year service lives for well-constructed stabilized base layers under the traffic loads typical of Korean rural roads. As with any road base, performance is contingent on drainage \u2014 water ingress from surface or subsurface sources is the primary mechanism of base deterioration for both FDR and conventional construction, and surface maintenance to prevent water infiltration extends the service life of both methods.<\/p>\n<\/details>\n<details style=\"padding: 16px 0;\">\n<summary style=\"font-weight: bold; color: #1a1a1a; cursor: pointer; font-size: clamp(14px,1.6vw+8px,16px);\">What happens if it rains during the THOR ST treatment operation?<\/summary>\n<p style=\"margin: 12px 0 0 0; color: #555;\">Light rain during the THOR ST milling pass has limited effect \u2014 the binder has already been distributed by the DCW 2.2 immediately before the rotor incorporates it into the soil, and the mixing action continues during the pass regardless of light precipitation. Heavy rain that produces surface runoff before compaction is a problem: it can wash binder material from the treated surface and dilute the binder-soil mix beyond the design water content, reducing final strength. If heavy rain begins during treatment, stop the milling operation, grade and compact the completed section immediately to minimise rain exposure, and re-assess the treated but un-compacted section for binder loss before completing compaction. Plan treatment operations around dry weather forecasts of at least 24 hours \u2014 see checklist item 8 above.<\/p>\n<\/details>\n<\/div>\n<p><!-- CTA --><\/p>\n<div style=\"background: linear-gradient(135deg,#1a1a1a 0%,#2e2e2e 100%); color: #fff; padding: 4%; border-radius: 6px; margin-top: 56px; text-align: center; box-sizing: border-box;\">\n<p style=\"font-size: clamp(17px,2.3vw+9px,26px); font-weight: bold; margin: 0 0 12px 0; color: #f07c00;\">Ready to Calculate Your Project ROI?
