As discussed above, the main contributing factor for the premature failures in this section was poor base/subgrade support. When coupled with heavy truck traffic volume and water intrusion from nearby embankment, the conventional FDR would not address the reoccurring failures. To improve the performance of FDR in JCP with poor base/subgrade support, an innovative FDR with two layers of steel reinforcements and tie bars to adjacent JCPs were proposed and implemented by the responsible district.

Some of the conventional Full-Depth Repairs (FDR) in Jointed Concrete Pavement (JCP) suffered recurring failures in less than one year. Under very heavy truck trafficking, tie bars were ruptured, and the slabs were settled for as much as 100 mm. This indicates the conventional method of slab replacement does not address the underlying problem. Falling Weight Deflectometer (FWD) and Dynamic Cone Penetrometer (DCP) were utilized to determine Load Transfer Efficiency (LTE) and base/subgrade support conditions, respectively. After one month of the ...
