水泥稳定碎石基层反射裂缝防治措施

结合湖北山区高速公路建设实践,针对山区高速公路水泥稳定碎石半刚性基层的沥青路面结构的特点,分析路面反射裂缝的机理,提出防治反射裂缝的技术措施,得出了在工程实践中应用骨架密实级配的基层和使用土工格栅可有效减少和延缓反射裂缝产生和发展.

Countermeasures to Reflective Cracking of Cement Stabilized Macadam Base

Combined with the highway construction practice in Hubei mountain districts, and in accordance with asphalt pavement structure characteristics as to the half-rigid base of cement stabilized macadam in mountain highway, this article analyzes the mechanism of pavement reflection cracking, proposes some technical measures to combat reflective cracking, and at last it comes to the conclusion that the application of framework-grading base and the use of geogrid in practical engineering can effectively reduce and delay the emergence and development of reflective cracking.
