Comparative analysis of the three major domestic asphalt pavement design platforms
In order to analyze the characteristics of the three major domestic asphalt pavement design platforms,including DAOKEDAO,GoodPave and HPDS,and compare the accuracy and rationality of its calculation results,this paper selected the structure type recommended in China JTG D50-2017 Design Code for Highway Asphalt Pavement,and transformed the structure thickness dimensions,by relying on the load parameters of Zhanhua-Linyi expressway project as well as axial load spectrum meas-ured within one year of Beijing-Shanghai expressway.The study showed that the difference in stress response between DAOKED-AO and GoodPave was small with a difference rate of no more than 0.5%,while the difference in stress response of HPDS showed volatility.The difference between DAOKEDAO and GoodPave in structural permanent deformation design results remained basi-cally the same,but the re sults by HPDS was obviously small.The calculation results of the three platforms in road meter accept-ance and anti-freezing thickness remained basically the same.
