沥青路面结构应力吸收层变形机理与功能层设计
$38.21
本书从工程实际出发,对应力吸收层的选取、变形分析、结构动力学分析和路用性能进行了阐述,重点讨论了应力吸收层的变形机理。应力吸收层是一种复杂的沥青功能层,主要由细集料、矿物填料和高弹性聚合物改性沥青胶结料组成,能随着基层的变形而变形,从而起到减缓和防治反射裂缝的作用。我国在应力吸收层的应用研究方面已取得一定的进展,但多数都是针对不同材料进行的研究,对结构应力和变形机理分析的内容相对较少,欠缺对环境和各种内部因素变化带来影响的考虑。因此,加强对应力吸收层结构行为及路用性能的研究就显得极为重要,这不仅可为广大工程建设者提供理论基础,同时也为应力吸收层的性能发挥及合理应用提供依据。
