In this paper , it also analyses the disadvantages of methods in present pavement specification . by means of parallel field test experimentation , and gives the correlativities between test methods of specification and new pattern test methods , such as road surface profiler , ground penetrate rada test system , friction test vehicle , falling weight deflectometer . based on these correlativities , their test and quality control standards are formed
本文还分析了路面现行检测方法存在的问题，通过现场不同方法的对比检测，建立了激光平整度测试车、探地雷达测试系统、摩擦系数测试车和落锤式弯沉仪( fwd )等新型检测方法和规范测试方法间的相关关系，从而提出新型检测的质量控制标准。
