Pavement design adopts the static index pavement design method; it has significant limitations for flexible asphalt pavement. This paper proposes asphalt mixture dynamic modulus determination method on the basis of existing research results at home and abroad. Dynamic modulus effect is studied on the mechanical properties of flexible base asphalt pavement, and the flexible base asphalt pavement performance is preestimated by the use of the dynamic modulus indicators in the paper.

Design Result

Asphalt layer modulus is one of the important mechanical parameters in pavement design. It will directly influence the design result and the mechanical properties of asphalt pavement structure. Using pavement design and analysis software, the effects of asphalt layer modulus on surface deflection, tensile stress at the bottom of base and sub-base course, stress at the the bottom of asphalt layer and service life of heavy load semi-rigid asphalt pavement structure were analyzed systematically. And the influencing laws were analyzed, too. The results indicate that the mechanical properties, deforming characteristics and service life of heavy load asphalt pavement were influnced significantly by asphalt layer modulus. With the increasing of asphalt layer modulus, the surface deflection, tensile stress at the bottom of base and sub-base course would significantly decrease, and service life of heavy load semi-rigid asphalt pavement structure would be improved.

Pavement Service Life

Calculation of structural course thickness is the primary task in pavement design. It will directly influence the mechanical properties, service life and the cost of pavement structure. Using BISAR3 of SHELL design method, the impacts of structural course thickness on the mechanical properties and service life of heavy load semi-rigid asphalt pavement structure were analyzed systematically. And the influencing laws of the thickness of surface course, base course and sub-base course on heavy load semi-rigid asphalt pavement service life were also discussed. According to the results of sensitivity analysis of structural course thickness and axle loads, a prediction model of service life of heavy load semi-rigid asphalt pavement was proposed. These achievements can contribute to determine the rational structural course thickness of semi-rigid asphalt pavement and ensure the service life of pavement consistent with the cost.
