Asphalt Crack Repair
CHICAGO’S ASPHALT CRACK REPAIR SPECIALISTS
When it comes to asphalt it’s easy to let proper maintenance slip through the cracks, and before long your asphalt will be besieged by cracks. By then, repairs can be costly or, worse, you may have to replace all the asphalt.
Every owner/manager in the Chicagoland area, area needs an asphalt preventive maintenance plan that includes asphalt crack sealing.
Depending on the initial construction and climate conditions, a crack sealing and maintenance plan can help asphalt last 10 to 15 years before major replacement is necessary.
The cost associated with an asphalt crack sealing plan is a fraction of the replacement cost. Surface cracks are often the first visible signs of underlying problems. Small cracks expand to form larger problem areas that have an “alligatored” appearance. Once this type of deterioration occurs, it is usually necessary to dig out the bad asphalt and install new sub-base and asphalt. Look for long cracks to appear where the seams were during initial construction These are the weakest areas in the asphalt mat.
Cracks should be filled as soon as possible to avoid water infiltration and expansion. There are many types of crack sealants on the market, but Done-Rite recommends a hot, pourable, rubberized, crack-fill material that meets Department of Transportation, State of Illinois Specifications and A.S.H.T.A specifications. It will have better results penetrating the crack and will be less likely to fail because of its ability to expand and contract with the extreme weather conditions in Chicago, IL.
Done-Rite Inc. Offers Two Crack Preparation Methods:
CRACK SEALING OPTION A
Rout, Blow and Fill
Technicians rout existing asphalt cracks to a width and depth of 1/2 inch or more. Routing equipment will have the ability to cut a flat vertical face on each side of the crack wall. They then thoroughly clean out dirt, loose debris and foreign material with pressurized air. The next step is to fill the cracks with rubberized hot-pour crack sealant. Filled cracks will be relieved of excess sealant to form a band of asphalt crack sealant which extends approximately one inch on each side of the filled crack.
