摘要
本文进一步讨论半刚性路面容许弯沉值,并论证沥青面层和半刚性粒料基层的合适厚度。根据室内梁式试件的疲劳试验结果,提出了沥青面层和半刚性材料的疲劳寿命预估方程和拉应力检验方程。
The paper discusses the permissible rebound deflection set for a semi-rigid pavement and the appropriate thicknesses of bituminous surfacing and semi-rigid granular roadbase. Based on the fatigue test results inlaboratory, the equations for estimating the fatigue life of bituminoussurfacing, semi-rigid roadbase and subbase as well as the equations forexamining the flexural tensile stress are suggested.
