Modulus Parameter Analysis and Calculation of Steel Deck Asphalt Pavement Material

Abstract:

The numerical analysis model and analytic formula, concerning flexural-tensile composite modulus of steel deck paving materials, were established with five-point loading composite beams, in order to explore the modulus value of steel deck paving materials. Regarding the three typical asphalt pavement material such as SMA10, GA10 and EA10, the composite modulus of paving material was calculated by analyzing stepwise loading data, and a universal flexural-tensile composite modulus range is proposed: SMA10 is 500 ~ 550MPa, GA10 is 500 ~ 600MPa, EA10 is 650 ~ 700MPa. The results show good agreement between the modulus of the numerical analysis method and analytical formula method. The proposed analytical formulas can calculate the flexural-tensile composite modulus more easily according to the actual load conditions, and the modulus value played a significant role in guiding the design and mechanical analysis of steel deck pavement system.
