常温液态压敏改性沥青薄层罩面技术

（一）技术简介—Technology survey
DS-CLFT冷拌冷铺薄层罩面技术是一种采用液态压敏改性沥青，配以开级配骨架空隙结构，在常温条件下运输、储存和拌合摊铺施工的施工工艺—DS-CLFT cold mixing and spreading thin layer overlaying technology is construction technology that uses liquid pressure sensitive modified asphalt, adds skeleton gap structure, and makes transport, storage, mixing and spreading construction under normal temperature.
（二）应用范围—Application range：
1、沥青路面的预防性养护和轻微病害的纠正性养护—Preventive maintenance of asphalt road surface and corrective maintenance of slight damage
2、新建道路的表面磨耗层—Surface wearing layer of new road
3、水泥路面"白改黑"—"White-and-black" of cement road surface
4、车辙修补—Track repair
（三）常温液态压敏改性沥青薄层罩面技术技术优势—Technical advantage
1、有效防止剥落，粘结防水层无需专门施工，修复轻微车辙，改善路面平整度— Avoid dropping effectively, no special construction of bonding waterproof layer is required, repair slight track, and improve road surface flatness
2、降低噪音，减少路面行车水雾，增强路面抗滑性能—Reduce noise, decrease road surface driving fog, and improve road surface skidding resistance
3、常温拌合，延长施工季节，降低道路养护费用—Mix under normal temperature, prolong construction season, and reduce road maintenance cost
