Asphalt Cracks are ugly and once they begin, they extend quickly and expand to become serious damage. Asphalt cracks can be caused by vehicle compression, car tires, oil, fuel and solvent spills, water erosion and penetration, frost heaves and earthquakes. Even asphalt that is properly sealed can result in asphalt cracks. Whatever the cause, cracks must be dealt with quickly and efficiently. If damage becomes too large, or there are too many cracks, asphalt may have to be replaced.

Standard asphalt repair methods are time-consuming, require significant labor and don’t last long. Roklin’s asphalt crack repair products provide several options, ready for use on most any asphalt repair project. Using Roklin’s simple methods, there is no need for major preparation—no grinding, drilling, pressure washing or saw-cutting. Simply sweep or blow out the damaged area, mix your materials and apply for solid asphalt crack repair.

Hairline Cracks

Equipment: Concrete Welder cartridge, broom, scraper

Sealing cracks can be done simply using Concrete Welder, available in a cartridge format. Make sure the crack is clean and free of moisture. Use a broom or blower to clean out any loose materials. If there is moisture, you can use a torch to dry it thoroughly. Open cartridge and squeeze Concrete Welder directly into the crack. Use a scraper or straight-edge to smooth the material out. Wipe up any excess material and allow to dry for 30 minutes. Now the crack is filled and ready for use.

Large Asphalt Cracks

Equipment: FloMix kit, broom or blower, drill, paddle-mixer, trowel

For larger asphalt cracks, use FloMix to stabilize and fill any voids. The polymer-based repair works in areas where the cracks are deeper and wider, because the material flows down to fill the entire space.

With no saw-cut or demolition required, the preparation is quick and easy. As with all polymer repairs, make sure that the damaged area is clean and dry, with no loose debris. Place the aggregate provided in the FloMix package to fill in the deeper area of the crack, without going above the surface of the damaged area. Using FloMix bottle “a”, carefully pour contents into provided 5-gallon bucket over the special sand. Next, shake bottle “b” thoroughly and pour into sand mixture. Mix with a paddle-mixer, using a drill. When mixture is completely wet, pour FloMix onto cracks and use a trowel or lute to smooth material into cracks. When cracks are smoothed out, toss topping sand by hand over repaired area to create a smooth surface. In colder months or when there is little time for the repair, catalyst can be supplied as an additive to speed the reaction. The newly-filled cracks can be ready in less than an hour.
