Using a Polymer-Based Sealant Material to Make Crack Repair of Asphalt Pavement



One polymer-based sealant was used for crack repair in asphalt pavement. The properties of the sealant were introduced. Flexure bending tests and slant shear tests were conducted to evaluate the bonding performance of the repaired specimens at different temperatures. The results of the flexure bending test showed that there was satisfactory bonding performance between asphalt concrete and the sealant material, especially at low temperatures (0°C~5°C). The shear strengths of the repaired samples from the slant shear test were all greater than the controlled specimens, indicating that there was a sufficient bonding between the asphalt mixture and the sealant material. For the repaired specimens, brittle failure occurred at low temperatures, whereas viscoelastic failure at high temperatures occurred in the asphalt concrete substrates. Field application of the sealant showed the satisfactory bonding behavior between the sealant and the asphalt concrete substrates.
