Management and preventive maintenance countermeasures of airport asphalt pavement;

Types of airport asphalt pavement structure,damage pattern,development trend of pavement design method are detailed as well as design indexes choosing,and new large aircraft oriented airport asphalt pavement design method and indexes are discussed,and Results show that fatigue crack,rut and low temperature crack are major damage patterns for pavement structure design.

Based on the practical construction experience of the repaving works of an international airport in Shanghai, the article sums up the main construction technological process of repaving the asphalt pavement under the condition of the non-suspending air service at night and the emergent handling scheme.

This paper calculates the loading stress and surface deflection of flight strip thin layer asphalt pavement with the finite element of three-dimensional isoparametric element,analyzes the effects of the subgrade resilient modulus,the base resilient modulus,and thickness in the completely continuous interface condition.
