Load Model and F Coefficient on Asphalt Pavement Deflection

摘要:

文章预览

Deflection is the important index of asphalt pavement design and the final acceptance. Using double circular load of Design Specification and four circular load of Benkelman test vehicle, the deflection was analyzed with four kinds of common pavement structures, the results show that the deflection of theoretical calculation was the Benkelman beam test 55%-75%, but Design Specification uses the F coefficient which less than 1 to correct the difference, the two have had the contradiction. The deflection of two and three axles load mode were analyzed, and compared with the axle load conversion coefficient C1. The result could provide the reference of axle load conversion and the correction coefficient for the pavement design.
