Based on the theory of three- dimensional isoparametric element and elastic layered system theory, using the large general finite element analysis software ANSYS, this article analyzed the load stress of the basalt fiber lean concrete base with asphalt pavement composite ( BFRLC + AC), deter- mined the critical load of pavement structure, and the reasonable length of BFRLC plate, studied the in- fluence of basalt fiber reinforced lean concrete base layer bottom stress by the different asphalt layer thickness,modulus of asphalt road surface, ...
