施工期荷载对半刚性沥青路面结构损伤的影响

Influence of Construction Period Loads on Semi-rigid Asphalt Pavement Structure Damage

半刚性沥青路面早期破坏的因素较多。当前虽采取一定的措施来防止早期破坏的发生,但仍未完全解决早期破坏现象。施工期荷载较重可能在施工过程中对结构产生影响,进而影响结构发生早期破坏;因此研究施工期荷载对结构的影响具有一定的意义。通过壳牌路面设计应力分析软件的计算,研究了施工期荷载对半刚性沥青路面结构损伤的理论影响。

There are many causes on early damage of semi-rigid asphalt pavement.Some measures are take to prevent early damage,but not yet fully resolve the phenomenon of the early damage. Heavy loads during construction period may have an impact on the structure,thereby affecting early damage of the structure. So,it has a certain significance to study the influence of construction period loads on semi-rigid asphalt pavement structure.Theoretical study on the influence of construction period loads on semi-rigid asphalt pavement structure damage based on the calculation of stress analysis by Shell Pavement Design Software is presented.
