沥青路面初期损坏分析

Analysis of Initial Damage of Bituminous Pavement

以福建省福州市城市道路的沥青路面为例,通过钻取产生初期损坏的沥青路面芯样,分析沥青混合料、路面结构、施工、荷载和环境等5个方面因素对沥青路面初期损坏的影响。阐明沥青路面初期损坏是由多个方面因素共同作用的结果,任何一个单方面因素都不能成为沥青路面初期损坏的决定因素。想要避免沥青路面初期损坏,必须全面分析,并制定切实可行的技术对策。

Take the Fujian Province Fuzhou urban road bituminous pavement as an example, through drilling the initial period damage bituminous pavement core type, thoroughly analyzed five influence aspect factors of the bituminous mixture, the pavement structure, the construction, the load and the environmental factor to the bituminous pavement initial period damage. It is considerded that the bituminous pavement initial period damage is a result which affects together by many aspect factor, any factor itself cannot become the determining factor to bituminous pavement initial period damage unilaterally. To avoid the bituminous pavement initial period damage, we must analyze comprehensively, and formulates the truly feasible technical countermeasure.
