The purpose of this paper is to evaluate the influencing factors of load transmission capacity of cement concrete slab joints in rigid-flexible composite pavement,so as to improve pavement performance and prolong service life.Through finite element simulation,the effects of modulus change,asphalt layer thickness,elastic modulus and thickness change on the load transmission capacity of cement concrete slab joints are investigated.Research has found that proper adjustment of these parameters can significantly improve the load transmission efficiency of joints.Based on the experimental data,the joint load transmission performance control index suitable for rigid-flexible composite pavement is proposed,which provides a new standard for pavement detection and maintenance,helps to optimize pavement design and construction,and ensures driving safety.
