摘要
由半刚性基层收缩开裂引起的反射裂缝已经日益成为我国沥青路面主要的破坏形式。论文通过对我国半刚性基层沥青路面的过去、现在和未来,即发展历史、现状和趋势的分析研究,论述了半刚性基层沥青路面反射裂缝形成的原因,提出了灌缝、超薄抗滑表层和纤维沥青混凝土的处治方式。结果表明,半刚性基层沥青路面随着施工工艺和处治方式的改进,使用寿命会更长。
Caused by shrinkage cracking semi-rigid base and the reflective crack has increasingly become the main form of damage of asphalt pavement in our country. This article through to our country the semi-rigid base asphalt surface analysis and study of the past, present and future, describes the reason for the formation of semi-rigid base asphalt pavement reflection crack, puts forward the crack seal, ultra-thin against sliding surface and fiber asphalt concrete way of treatment. The results show that the semi-rigid base asphalt pavement as the improvement of construction technology and the way of treatment, would have a longer service life.
