利用专门的道路设计程序,对半刚性基层沥青路面进行结构力学计算。通过沥青路面内的应力大小和分布分析,得到层底拉应力随结构力学参数(各材料层厚度、模量及结构形式)变化规律,据此提出避免沥青面层疲劳开裂和半刚性基层反射裂缝的沥青路面合理结构,并指出基于抗裂的沥青路面材料组合设计方向。研究结果对半刚性基层沥青路面结构组合设计具有理论参考价值。
利用專門的道路設計程序,對半剛性基層瀝青路麵進行結構力學計算。通過瀝青路麵內的應力大小和分佈分析,得到層底拉應力隨結構力學參數(各材料層厚度、模量及結構形式)變化規律,據此提齣避免瀝青麵層疲勞開裂和半剛性基層反射裂縫的瀝青路麵閤理結構,併指齣基于抗裂的瀝青路麵材料組閤設計方嚮。研究結果對半剛性基層瀝青路麵結構組閤設計具有理論參攷價值。

In this paper, a special road design program is used to analyze the stress value and distribution of the semi rigid asphalt pavement under normal tire pressure. Based on calculating analysis, some conclusions are obtained, such as the change law of the stress in layer bottom caused by the altering of construction mechanics parameters, the rational as- phalt pavement construction based on the change law which could avoid the fatigue cracking and reflection cracking and the design direction of anti-cracking asphalt pavement' s material composition. The research resuhs would have theoretical reference value for the structural design of semi-rigid asphalt pavement.
