摘要
GTM的设计思路提出解决目前汽车触地压强不断上升的途径,应用GTM可减少沥青路面在重载交通下出现车辙、推移等剪切破坏。试验证明,沥青路面的表现与GTM的设计指标存在良好的相关性,因此GTM具有很好的推广价值。
The design thoughts of gyratory testing machine （GTM）solves the problem that the pressure of car giving to road rise constantly and the application of GTM can reduce the destroy of bitumen pavement under overload vehicle, such as rutting, move and other shear destroy. The test experiment shows that there are good relationship between road performance and gyratory testing machine design index, so, GTM has much value to popularize.
