摘要
轮胎接地压力测试方法主要是压力传感器法.对沥青路面结构力学特性的研究来说,已有的轮胎接地压力测试装置及测试结果有一定的特点和局限性.基于这些考虑,开发了一套轮胎接地压力静态测试仪.该测试仪是一种单点测试法,并将压力传感器置入沥青混凝土,很好地模拟了实际路面结构的受力特性.实际测量结果表明该仪器准确可靠.
The main measuring method of tire contact pressure is using stress sensor.However,these devices have some characteristic and limitation respectively to the research of mechanics response for asphalt pavement structure.So the authors have developed a static measuring device for tire contact pressure.Each datum from this device is gained by single stress sensor which is buried into asphalt concrete that can simulate the mechan- ics characteristic of asphalt pavement.Some test results prove that this device is credible.
