摘要
针对沥青碎石柔性基层作为高等级公路的应力消减层和排水层,综述了沥青碎石混合料的力学性能与抗永久变形能力、抗疲劳性能、空隙率与排水性能及水稳性的关系的研究现状,并提出了一些认识。
Targeting at using asphalt debris flexible base course as stress elimination layer and water drainage layer for high-grade highway, this paper introduces current study on mechanical property of asphalt debris mixture, its relationship with anti permanent deformation, anti - fatigue performance, void percentage, water drainage performance and water stability, etc. and gives some know how.
