Re-damage analysis and prevention of craks repairing for asphalt pavement

通过对再破损的产生原因分析能够掌握其防治与改善途径,针对沥青路面裂缝修补的填封修补再破损,根据其内涵确定了三种表现类型,并具体分析了各自可能产生的原因,结合裂缝填封的受力变形分析,提出了室内试验选材控制要求方面及防治裂缝填封再破损的技术措施。

To analyzing the causes of the damage is beneficial to prevent distresses of cracks repairing and improve the cracks repairing technique.The three types behaviors according to its meaning for the re-damage in pavement crack repairing is determined,and their possible causes is analyzed specifically. By analyzing the deformation of the crack repairing material under stress,the laboratory tests and their control requirements for repairing material is counseled,and the technical measures of distress prevention for cracks sealing or filling is proposed.
