Good asphalt maintenance is a must in order to extend the life of your driveway or parking lot and to keep it looking new. We use a formulated sealer mixture consisting of emulsified asphalt, sand, clay and mineral fillers. We apply the sealcoat by hand using a squeegee to protect and preserve the integrity of the pavement. Surfaces that remain unprotected will develop hairline cracks which allows the elements to penetrate the surface of the driveway or parking lot. This will lead to the premature failure of your asphalt. You are able to extend the life of your asphalt substantially with a pavement maintenance program.
Water is one of the most damaging elements to your asphalt surface. When frozen, water expands in size and becomes one of the strongest forces in nature. This problem is extremely prevalent in the Portland Metro area due to our climate. The problem with water collecting in the pores and cracks of asphalt is that the surface freezes first, forcing the ice to move downward. This, in turn, will cause deep cracking of the asphalt down to the gravel base which will soften and damage the integrity of the base leading to further deterioration of the asphalt surface. If water is continually allowed to penetrate the surface of the asphalt, the effect of the freeze and thaw cycle will destroy the asphalt in a short period of time.
Sealcoat fills the naturally porous surface of asphalt, protecting it from the damaging effects of water, gasoline, oil, diesel, salt, cleaning products and chemicals.
Sealcoating will also restore the elasticity to the surface of the asphalt. Asphalt is elastic by nature since it expands and contracts from the heat of the sun. Asphalt, being black in color, absorbs heat from the sun very efficiently. If the asphalt is left unprotected, the heat will dry out the blacktop and cause it to become brittle. This will lead to cracking and “alligatoring” followed by premature failure of the asphalt. After the asphalt has failed, the only option is to replace which is costly compared to preventative maintenance.
Weeds tend to grow through cracks and breaks in the asphalt. At JAM Sealcoating Inc, we clean and fill in all cracks using a hot rubberized crack filler before sealcoating. This keeps the vegetation from growing back. Moss and weeds have a difficult time growing through a sealed surface. Call today to request a free pavement maintenance estimate in Portland.
