US12 Joint Leveling Evaluation

Transverse cracking in asphalt is almost unavoidable due to South Dakota's ever changing climate. Bitterly cold winters lead to thermal cracking through the contraction of the asphalt concrete. Moisture is another major enemy of asphalt concrete that causes further deterioration of the adjacent area near the crack. The South Dakota Department of Transportation (SDDOT) has an aggressive crack routing and sealing program to help minimize the moisture ingress but sometimes these cracks may undergo significant subsidence in the asphalt concrete pavement adjacent to the cracks even with the sealing. The depressions that form result in an unacceptably rough ride die to dips at each crack. To potentially solve this problem on US12 near Selby, SD, four test sections using three different materials and two different processes will be constructed. Deery Level and Go, Deery Recessed Repair, and Crafco PloyPatch will be used to fill and level the depressions. The products will be tested in milled and non-milled sections, which will provide ample opportunity for testing and evaluating of their effectiveness. The Deery and Crafco products are similar forms of hot pour mastic material containing aggregate. This research will evaluate the products and will help to determine whether either product will be successful. The objectives of this research project is to: (1) evaluate the effectiveness of joint leveling mastic materials as a maintenance practice; (2) determine the degree of ride quality improvement from the joint leveling applications; and (3) determine the economical benefit of joint leveling as a maintenance practice.
