摘要
在调查了解国内外许多旧路改造实践工程的前提下,提出采用钢筋马钉锚固相邻水泥混凝土板来进行沥青混凝土罩面改造的方法,增强加铺改造后路面的整体防止反射裂缝效果。为确定可行性,采用国际著名的通用有限元软件ANSYS对其温度应力和荷载应力进行了计算和分析。计算结果表明该法对防止或减缓旧水泥混凝土路面上沥青混凝土罩面层的反射裂缝是有效的。
On the premise of research on old cement concrete overlay engineering home and abroad,this paper put forward the method of anchoring the adjacent concrete slab by rivets in order to improve anti-cracking ability of asphalt pavement overlay.This paper used ANSYS to calculate and analysis temperature stress and load stress,the results certified that this method is effective on prevention or mitigation of reflective cracking in asphalt overlay on old cement concrete pavement.
