PERFORMANCE EVALUATION OF HOT AND COLD POUR CRACK SEALING TREATMENTS ON ASPHALT SURFACED PAVEMENTS

This is the second report from the Center for Transportation Research on the Project 4061. It presents the results, findings, conclusions, and recommendations based on the field surveys of the test sections for the second year of a 3-year study. This study comes as an attempt to determine the feasibility of using both hot pour and cold pour sealants. This will be achieved by comparing the long-term performance of both hot and cold pour sealing materials. For the purpose of the study, seven sealing materials were selected; four hot pour sealants designated as H1, H2, H3, and H4 and three cold pour sealants designated as C1, C2, and C3. These materials were applied on eight pavement maintenance sections for testing purposes in five districts in Texas. The investigation on test sections was based on AASHTO P20-94, "Standard Practice for Evaluating the Performance of Crack Sealing Treatment on Asphalt Surfaced Pavements." Three investigation visits were conducted; the first one about three months after the construction (Summer 2001), the second one about one year after the construction (Winter 2002), and the third one which was completed approximately 18 months after the construction (Summer 2002). The visits indicated relatively excellent performance for the hot pour sealants in the majority of the test sections. On the other hand, cold pour sealants showed drastic decline in their performance with time.
