碎石封层技术在公路工程中的应用探讨

The Appcication of Chip seal Technology in Highway Engineering

碎石封层技术是一种在喷洒沥青类结合料后立即撤布一定粒径的粗集料,经碾压而形成薄封层的技术,可以有效提高路面的防水性能,减缓沥青老化的速度,提高路面的粗糙度和抗滑能力,使行车更加安全。碎石封层可作为开展预防性养护的突破口,全面提升青海地区的公路状况和养护水平。

Crushed stone seal technology is a kind of binder spray asphalt must be removed immediately after cloth grain size of coarse aggregate,after rolling to form a thin layer sealing technology,can effectively improve the waterproof performance of pavement,reduce the speed of the asphalt aging,improve the road surface roughness and the anti- sliding ability,make driving safer. Crushed stone seal layer can be used as a breakthrough point to carry out preventive maintenance,fully improve the road condition and maintenance of qinghai region.
