New High Temperature Pavement Joint Sealants

We propose to develop and test a new, non-silicone polymer product to resist short term heat exposures in the range of 700°F or higher. This formulation shall be equal to or better than silicones or polysulfides in chemical resistance to both jet fuels, and hydraulic fluids. The material will be weather resistant and will maintain flexibility in all climates. The joint sealant will be designed and formulated for long term use on concrete pavements exposed to thermal cycling, sunlight UV exposure, wind, rain, snow, high humidity, air oxidation, microbial organisms, marine climates and hot dusty conditions. The advantages of aromatic polyurea are as follows: 1. Quick gel time and cure as short as 30 seconds 2. Quick installation time 3. Prior experience in airfield joint protection 4. Can be installed at low or high ambient temperatures 5. Weather resistant 6. Proven technology
