复合增效型沥青混凝土薄层罩面在旧水泥混凝土路面上的应用

Application of composite synergistic asphalt concrete thin top layer on old cement concrete pavement

对于旧水泥混凝土路面最适合的改造措施是加铺沥青混凝土面层。复合增效型沥青混凝土CSA-10摊铺厚度仅2.5 cm,使用高强度改性沥青,复合增效剂和温拌剂,并结合相应的施工工艺,保证了沥青混凝土薄层罩面的压实度以及与旧水泥混凝土板块的粘结性。2.5 cm的复合增效型沥青混凝土CSA-10薄层罩面技术作为旧水泥混凝土路面的改造措施,性能良好,造价经济,节能减排,值得推广应用。

Paving asphalt concrete overlay on the old cement concrete pavement is a common and most effective measure to improve the pavement performance and extend the pavement life . The paving thickness of composite synergistic asphalt concrete CSA-10 is 2.5 cm . The additives of high strength modified asphalt , composite synergistic agent and warm mix agent are used to ensure the compaction degree of asphalt concrete thin top layer and the viscosity between the old cement concrete pavement and the asphalt concrete thin top layer , combined with the corresponding construction technology. 2.5 cm CSA-10 asphalt concrete thin top layer technology is worth to popularizing and applying because of its excellent performance , lower cost and energy saving and emission reduction .
