| 摘 要： | 研究了江苏省沿江高速公路永久性路面试验段的路面使用性能和经济适用性.对试验段路面性能进行连续监测,对比了通车以后8年内含有富油抗疲劳层(RBL)的永久性路面、不含富油抗疲劳层的永久性路面与普通半刚性基层沥青路面的弯沉、裂缝和车辙状况及发展规律,并通过全寿命周期费用分析法(LCCA)对各路段进行经济评价.通过性能对比和LCCA分析发现:含富油抗疲劳层的沥青结构具有良好的抗裂缝性能,但是抗永久性变形能力不足;传统的半刚性基层沥青路面因在服务寿命内需要更频繁的养护而经济性不足.研究结果表明:不含富油抗疲劳层的永久性路面结构是本地较为适用的一种永久性路面结构.

| Abstract: | Pavement performance and economic efficiency are researched on the perpetual test pavement of Yijiang-Suzhou Express Highway in Jiangsu province, China. Test sections were continuously monitored. The conditions and developing laws of deflection, rutting and cracking are compared among the perpetual pavement with the rich binder layer （RBL）, the perpetual pavement without the RBL, and the conventional semi-rigid asphalt pavement in the past eight years after opening for traffic. Economical evaluation is conducted via life cycle cost analysis （LCCA）. Based on the performance comparison and LCCA analysis, sections with the RBL have good crack resistance, but they are not very satisfactory in the aspect of permanent deformation; the conventional semi-rigid asphalt pavement is the least economic one due to requiring more frequent maintenance. Research results show that the perpetual pavement without RBL is a more appropriate structure for the test site. |
