| Abstract: | After analysis and comparison of the bearing performance and anti-fatigue performance of the modulus and thickness in the different base courses of the pavement by the numerical calculation method, it is given that the enhancement of the base course modulus and the increment of the base course thickness can obviously improve the bearing performance of the pavement, enhance the fatigue service life of the pavement, and it is further pointed out that the enhancement of the base course modulus can be realized by changing the gradation of the base course. |
