SUBSEALING AND LOAD TRANSFER RESTORATION

Presented are the evaluation results of slab subsealing and load transfer restoration using dowel bars and double vee shear devices of a jointed concrete pavement at a large truck terminal facility. Nondestructive deflection testing (NDT) procedures using the falling-weight deflectometer (FWD) were used before and after slab subsealing and installation of the load transfer devices to evaluate the efficiency of the slab subsealing and load transfer devices.
