Improved Crack Sealant Application Methods

The Performing Agency shall determine the routing standard for Texas pavement by performing a comprehensive review of all known literature for routing as it pertains to crack sealing, as well as those factors impacting sealant performance. Surveys will yield data for Texas' methods, as well as other states' practices and preferences. The installation and monitoring of five test sites will provide data from installation through normal use over two years. The data gathered by the research team will be assessed against current knowledge on: the performance of sealed cracks under various traffic, climate, and existing pavement conditions; the performance of sealant under various cracks routing configurations; and the effects of these methods on pavement roughness, user perception, and estimated future maintenance and rehabilitation costs. The research team will present all of this information in a comprehensive final report, along with a simple comparison chart of sealant types and methods highlighting short- and long- term costs and benefits of routing prior to crack sealing.
