Testing and Evaluation of Asphalt Pavement Structural Performance

Test and evaluation of pavement structural performance is important to asphalt pavement maintenance management.Based on the test,we can judge the pavement condition and the rate of deterioration,and make decision whether rehabilitation is needed.The paper discussed the popular technique and equipments for deflection test,analyzed the method and index for pavement structural performance evaluation,presented the modified computational method,set up index conversion model,and recommended the rating standard for corresponding index.
