摘要
沥青路面裂缝破坏按几何形状头分为龟裂、块裂、纵裂、横向裂缝、反射裂缝、滑移裂缝;按裂缝列成分为荷载型缝与非荷载型裂缝。沥青面层出现裂缝如得不到及时治理,路面裂缝造成的沥青路面损坏,已成为沥青路面早期破损的主要类型,本文对沥青裂缝的类型,裂缝原因分析、裂缝对路道的损坏,以及如何防止出现沥青路面裂缝进行了较为详细的论述。
Destyor of asphait pavement crack falls into fissuration,block crack,longitudinal crack,reflection crack,sliding crack in terms of geometric configuration and falls into loading crack and non-loading crack in terms of formation of crack,in case the crack on asphalt covering cannot be controlled in good time,new crack will occur arouud the oid one under the action pf rainwater and heavy loading,which will result in biock fragmentation of pavement finally,Destroy resulting from crack of asphalt pavement has been the main type of early destroy of asphalt payement,The text makes an analysis on type,cause,damage of crack to road of asphalt pavement crack and how to prevent asphalt pavement from occurring cracks in detail.
