The Hawaii Asphalt Paving Industry (HAPI) September newsletter discussed an aspect of the Kalakaua project covered in AsphaltPro‘s January 2025 issue that delved into additional pavement maintenance steps. HAPI shared:
Rapid Repair™ System by HAPI member Tensar was used on the project. It is a repair system intended for the reinforcement of jointed superstructures, single cracks and small localized areas.
The PG100 pavement patches are made up of a fiberglass reinforcement bonded to a polymer-modified layer of asphalt. The PG100 pavement patches are specifically designed for the manual repair of small areas and can be installed directly on milled surfaces after the application of a tack coat. The Rapid Repair PG100 pavement patches slow and reduce reflective cracks by turning crack stresses horizontally to dissipate stress. The pavement patches can also be used for covering trenches, base repair patches, and lane widening.
The Tensar website explains best practices for its process:
Step 1. Ensure the surface is clean, dry and free of dust.
Step 2. Use a tack coat or primer on heavily oxidized areas, milled surfaces and concrete surfaces.
Step 3. Lay the pavement patch over the area of repair and roll over it with a rubber tire to adhere the patch to the surface.
Step 4. Cover with a minimum of 1.5 inches (4 cm) of hot mix asphalt.
