国道109线橡皮山段沥青混凝土路面冷再生技术应用

State Road 109 Line Eraser’s Hill Section of Asphalt Concrete Road Surface Cold Reclamation Technology

沥青混凝土路面由于其在重交通量及地质不良等情况的影响下,以及其本身结构设计的原因,容易产生网裂、推移、坑槽等病害.采用一般的处理方法,是将原路面挖除,重新进行结构层的铺筑.国道109线橡皮山段冷再生技术的应用充分利用老路面结构材料,掺加骨料、石灰等材料,一次再生、摊铺、碾压成型,做为新路面基层加以利用,节省了投资,加快了施工进度,病害整治成效显著.

Asphalt concrete pavement due to heavy traffic volume, and geology in the adverse impact of such conditions, as well as its own reason for mechanical design, easy to produce net crack, passes, pits and other diseases. The general approach adopted is the original road excavation, re-paving the structural layer. State Road 109, Line Eraser’s Hill section of the application of cold recycling technology take full advantage of the old pavement structure, material, admixing aggregate, lime and other materials, a regeneration, paving, rolling forming, as a new road pavement, grass-roots level to use, saving the investment and speed up the construction schedule, Disease Treatment with remarkable results.
