摘要
本文在对国内外弹性层状体系统理论各种解法、沥青路面车辙深度各种算法及各种材料流变模型评定和研究的基础上,建议采以L aplace变换中的初值定理和终值定理求解的方法。文中结合室内试验和现场测定结果及有关参数(包括年平均有效气温MAAT_(eff)和沥青面层的有效温度T_(eff)沥青混合料的劲度S_(mlx)和瞬时回弹模量E、动态影响系数C_M)的确定,对沥青路面车辙深度的计算和预估提出了一种简易可行的方法,并备有可在IBM-PC机和国产长城机上应以的程序GHT88-1。
On the basis of the review of a variety of solutions for the viscoelastic layer system theory and the calculation methods for the rut depth in the asphalt pavements as well as various creep models a solution through the agency of both the initial value and the final value theorems in Laplace transform has been proposed in this paper, A simple and feasible method for predicting the rut depth in the asphalt pavement has been suggested incorporating the results of laboratory test and field measurements, the relevant parameters consist of the mean annual effective air temperatures, the effective temperatures for the sub-layers of the asphalt surface, the calculation and prediction of rut depth can be performed on the programme GHT88-1 on IBM-PC or domestic Great Wall computer, The stiffness and the resilient transient moduli of the asphalt mixtures as well as the dynamic effect correc tion factor.
