江苏宁通公路六合东至江都段旧水泥混凝土路面于 1998年采用沥青混凝土加铺改造 ,结合改造工程设计了 11段不同加铺方案进行试验观测。 5年来 ,通过对试验路构造深度、摩阻系数及裂缝检测与观察 ,分析了各方案的使用状况。
In 1998, the old cement concrete pavement on the road from Liuhe to Jiangdu in Jiangsu Ning-Tong Highway was retrofitted with asphalt concrete. In combination with retrofit engineering, 11 different pavement schemes were designed and tested. In the past five years, by analyzing the depth of construction, the friction coefficient and the crack detection and observation of the test road, the use of each program has been analyzed.
