IDENTIFICATION AND DETECTION OF A VOID UNDER HIGHWAY CEMENT CONCRETE PAVEMENT SLABS BASED ON FINITE ELEMENT ANALYSIS

For a city, the construction of a road is related to the development of economy, and the construction of a road includes maintenance of the road. Cement roads have been popularized in road construction due to their low construction cost and high strength, but at the same time, road problems have ari...
