摘要
由沥青和沥青混合料的劲度模量的常规数学公式,建立劲度模量和路面温度变化的线性关系,并考虑路面温度场的变化规律,根据Hills累计温度应力理论,用积分求出各面层的温度应力,编制沥青混合料温度应力的通用程序,在输入沥青和沥青混合料的几个常规指标后,便可直接得出沥青面层的温度应力,并和相应的TSRST试验数据作对比,结果相符。
The linear relationship between the stiffness modulus and the temperature changes of the road was established according to the conventional mathematical formula of the stiffness modulus of asphalt and asphalt mixture. Based on the surface of the road surface temperature field, the surface temperature stress was solved by integral according to Hills cumulative thermal stress theory. Then, a current program for the temperature stress of asphalt mixture was worked out. This program can output the asphalt surface temperature stress directly after several conventional indicators of asphalt and asphalt mixture are input. The results adapt to the corresponding TSRST Test data by comparison.
