沥青玛蹄脂碎石混合料(SMA)是近年在高级路面上面层广泛应用的一种新型沥青混凝土材料,并以其优良的抗车辙和抗滑性能闻名于世。通过临合高速SMA路面的铺筑,着重分析了在高海拔大温差地区铺筑SMA路面的适用性和施工要素。
Asphalt mastic asphalt (SMA) is a new kind of asphalt concrete material widely used in the top surface of advanced pavement in recent years, and is famous for its excellent anti-rutting and anti-skid performance. Through the paving of the high-speed SMA pavement of Linhe, emphatically analyzed the applicability and construction elements of paving SMA pavement in the area of high temperature and large temperature difference.
