摘要
应力吸收带可以有效地吸收新旧路面搭接处的应力,减弱半刚性基层反射裂缝向沥青面层的传递,最大限度地减少沥青路面裂缝,提高道路的使用寿命和使用质量,因此应该推广应力吸收带在旧路加宽中的应用。
Stress absorption zone can effectively absorb the stress in the lap joints between new and old pavements,weaken the transmission of semi-rigid reflection crack to asphalt pavement,furthest reduce the cracks in asphalt pavement and enhance the service life and quality of road.Therefore,the application of stress absorption zone should be promoted in widening old road.
