摘要
为探求开放交通初期沥青路面结构在行车荷载作用下的力学响应,通过室内试验,获得了半刚性基层材料分别在10,20℃温度下,7,14,21,28,35 d的路用性能参数;利用KENPAVE软件计算出龄期、轴载、温度等因素作用下竖向位移、压应变、拉应力等指标的变化规律。实际检测表明:计算结果是正确的。
To explore the mechanical response of asphalt pavement structure under vehicle loads in the early period of highway open traffic, firstly, the road performance parameters of pavement material in 7, 14, 21,28, 35d at 10 ℃ and 20 ℃ were gained through laboratory experiments. Then the variation rule of vertical displacement, compressive strain and tensile stress under factors, such as age, axle load and temperature was calculated out by utilizing KENPAVE program. The correctness of the calculation results was verified by actual detection.
