41 Hot Pour Mastic/Patch ($$) Mastic seal is a type of thick, viscous asphalt material that is used to repair larger cracks, alligator cracking, cupping cracks, raveling, shoving, utility cuts, micro trenches, shallow depressions, rumble strips, potholes and depressions. Mastic can be used in both asphalt and concrete pavements. It is a blend of asphalt binder, fibers and aggregates that form a flexible and adhesive compound capable of filling and sealing irregularities in pavement surfaces. The characteristics and benefits of mastic include: • Preparation: Mastic can be used for ongoing pavement issues that come up at any time of the year. Mastic should also be installed at the same time as crack seal to prepare roads before any surface treatments planned for the summer. • Durability: The material is designed to be highly durable and flexible, which allows it to accommodate the movements of the pavement and the changes in temperature without cracking. • Adhesion: Mastic seal adheres well to the pavement surface, providing a strong bond that helps to prevent water infiltration and further deterioration of the pavement. • Load Bearing: It can withstand heavy traffic loads, making it appropriate for use in both low- and high-volume traffic areas. • Ease of Application: Mastic can be applied relatively quickly and does not require the removal of the existing pavement. • Smooth Transition: When applied properly, it creates a smooth transition between the existing pavement and the repair area, which can improve ride quality. • Waterproofing: By sealing cracks and joints, mastic helps to prevent water infiltration, which is a leading cause of pavement deterioration. • Longevity: Repairs made with mastic tend to last longer than those made with more traditional patching materials, leading to longer intervals between maintenance. Hot pour mastic/patch is typically applied using specialized equipment that heats the material to the required application temperature. It is then poured into the prepared area and leveled to match the surrounding pavement surface. It is a highly effective pavement preservation method for addressing intermediate to large-scale distresses that are beyond the capabilities of crack sealants but not yet severe enough to warrant complete pavement replacement.
