摘　　要：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, AC overlay on PCC pavement is constructed on Liuhedong ～ Jiangdu Section of Ning-Tong Highway in Jiangsu Province. At the same time, 11 trial pavement sections with different overlay design are constructed, experiments and inspections have been proceeded till now. By the analyses on texture depth, friction coefficient and cracking of the pavement, the performance of different trial pavement sections are estimated and some rules brought forward, which can be used for reference in similar situation.
