经济型SMA混合料是一种新型的沥青混合料结构,与普通沥青混凝土路面相比,具有更好的抗车辙、抗裂、抗滑、水稳定性及耐久性等优点。通过对经济型SMA路面长期检测表明,经济型SMA路面抗车辙、抗滑性、抗裂性、水稳定性和耐久性等性能较普通沥青混凝土路面都有很大的提高,但施工控制较普通沥青混凝土路面也有更高的要求。结合工程实例,对承德地区的经济型SMA路面施工经验进行了总结,供大家在以后的施工当中借鉴。
Economical SMA mixture is a new type of asphalt mixture structure, which has better anti-rutting, anti-cracking, anti-skid, water stability and durability compared with ordinary asphalt concrete pavement. Through the long-term testing of economical SMA pavement, the performance of anti-rut, anti-sliding, anti-cracking, water stability and durability of economical SMA pavement has been greatly improved compared with common asphalt concrete pavement, Asphalt concrete pavement also have higher requirements. Combined with the engineering example, the construction experience of economical SMA pavement in Chengde area was summarized for reference in future construction.
