Orthogonal Analysis on Responses Indexes of Asphalt Pavement
The asphalt layer thickness, base thickness, the modulus of the asphalt layer, base modulus and subgrade modulus are selected as the responses indexes of asphalt. The level of each factor corresponding parameters and test results table are established by orthogonal analysis for four-level table of five factors. This paper took the Shell Designing Software BISAR 3.0 as calculation tool to get the three-dimensional response results of the different kinds of asphalt pavement. Based on results, the course bottom tensile strain of the asphalt layer, subgrade compressive strain and maximum shear stress of asphalt pavement are analyzed by intuitive analysis, variance analysis, and sensitivity analysis. It is found that the sensitivity analysis is a more accurate analysis of the factors of the factor in the level of assessment indicators. Response to the degree of influence of various factors on the pavement mechanics, pavement structure design and material design should be selected according to road type of damage specifications. In accordance with the sensitivity analysis of the impact of factors based on balanced other design specifications.
