| 摘 要： | 通过激光断面综合测试仪，对路面性能指标——平整度、横向力摩擦系数和表面回弹弯沉值进行测试，发现平整度、横向力摩擦系数都在可接受范围内，特别是回弹弯沉代表值没有出现显著下降，其对理论研究及工程实践具有一定的参考价值。

| Abstract: | ing deflection roughness and ing deflection Pavement performance indexes like roughness, sideway friction coefficient and reboundare tested through comprehensive tester of the laser cross-ection. The results show that sideway friction coefficient are within the scope of acceptation. Especially the reboundrepresentative value has not decreased obviously. It is of great significance to the theoretical research and engineering practice. |
