Study on Mechanical Responses of Typical Asphalt Pavement Structure

Article Preview

Abstract:

Semi rigid asphalt pavement, flexible base asphalt and composite base asphalt pavement are the main structure forms of asphalt pavement. The mechanical distributions are different in those structures. Based on elastic layer system, this paper took the Shell designing software BISAR3.0 as calculation tool to get the tensile strain of three kinds of models, the distribution of main mechanical response were compared with each other using the ORIGIN8.0. Then a comprehensive analysis was made based on the mechanical response distributions of the three structures. The results show that: flexible tensile strain and vertical strain in the bottom of asphalt layers of semi rigid base structure is the smallest, as it shows better performance. It proves that the design specification adopting now is not suitable for semi rigid base pavement
