Pavement cracks develop due to expansion and contraction caused by temperature fluctuation. These cracks allow water to penetrate the pavement base and sub-base materials, causing pavement elements to lose structural integrity. If not repaired or prevented this cracking effect will grow, leading to deformation of the pavement, pot holes, and ultimately the degradation of asphalt and concrete surfaces.
Cracksealing is preventive maintenance against water from further damaging roads. The use of hot and cold-applied sealants minimizes water penetration, sub-surface ice formation and traffic erosion. Most importantly, cracksealing lengthens the life of roadways, parking lots and patios made of asphalt or concrete. According to several of the country’s DOTs, with timely preventive cracksealing the useful life of highway pavements can be extended up to 10 years in comparison to other temporary surface treatments such as chip seals, micro paving, thin overlays and slurry seals. As an added benefit, cracksealing is executed at one-sixth the cost of conventional pavement rehabilitation or reconstruction.
Keep in mind, cracksealing is preventative maintenance, not reconstruction. When a roadway or parking lot is "alligatored" or has incurred more extensive damage than a few cracks, the area must be cut out and replaced or patched.
Benefits of Crack Sealing
Saves You Money - For pennies on the dollar, you can avoid costly asphalt replacement with crack sealing performed by the professionals at Camelback Paving, Inc. The cost of replacement can be 20 – 30 times more expensive than a single maintenance procedure.
Prolongs Pavement Life - Routine Maintenance (proper crack sealing and sealcoating) can double the life of your asphalt. Crack sealing is the SINGLE MOST IMPORTANT STEP you can take to prolong the life of your asphalt.
Slows Oxidation - Left untreated, cracks allow water into and beneath the base which leads to pavement failure. Water is the number one enemy of asphalt.
Prevents Water Penetration - Weather-proofing agents repel water – the number one enemy of asphalt. Asphalt is naturally porous; left unsealed, water will pentrate through the pores and cracks and disturb the base – eventually leading to failure of the pavement.
Improves Appearance - First impressions of your home or place of business are greatly enhanced with a deep, rich, satiny black finish.
Crack Sealing Facts
Small cracks allow moisture into asphalt.
Water expands and contracts with temperature causing larger cracks.
Larger cracks allow more water penetration to weaken base.
Weaknesses in base accelerate asphalt failure.
Small cracks always become big cracks.
Big cracks soon become potholes.
Cracks ¼” and larger can be sealed with specially formulated hot rubber sealant.
