摘要
Abstract
As a large gap structure pavement,drainage asphalt pavement has excellent drainage noise reduction func-tion and skid resistance performance.But,its mechanical response still need be cleared in service.The finite ele-ment model of drainage asphalt pavement is established by ABAQUS software under the coupling effect of tempera-ture-mobility load.The temperature distribution of different structural layers and the response characteristics of transverse,longitudinal and vertical stress and strain are analyzed.The results show that the heat transfer coefficient of porous structure of drainage asphalt pavement is lower,which hinders the transmission of temperature and causes the slower rise of internal temperature;Under load,the pavement undergoes alternating tension and compression,and the stress change under the rear axle is the most obvious.The stress change of the steering axle is weaker.And the stress of the asphalt layer within the wheel contact range gradually changes from compressive stress to tensile stress outward;The tensile stress at the bottom of the asphalt layer is significantly higher than that of other structural layers.The strain gradually changes from compressive strain to tensile strain with the increase of depth.Tensile fail-ure is easy to occur under repeated loads,and the strain at the bottom of the base reaches the maximum values.The research results can provide a theoretical basis for the construction and optimization of drainage asphalt pavement of expressway under construction.关键词
