We do it all from residential driveways to commercial parking lots. Here's a little history on asphalt and what we do. What is Asphalt? Asphalt is a combination of approximately 95% sand, rock or gravel-mixed with approximately 5% asphalt cement, a product of crude oil. This mixture is heated and mixed together in an asphalt plant at around 300°F, and hauled to an asphalt paving crew. The HMA is fed into an asphalt paver placed in a continuous, smooth ribbon behind the paver where it is rolled and compacted into place. This continuous flow of material and the flexible nature of asphalt pavements provide the traveling public with the smooth ride they have come to expect. The ability to turn traffic onto a newly paved roadway with no “curing” time means fewer delays, less construction, and safer roads. Asphalt Magic will beat any asphalt company in San Antonio's price! No Job to Big or Small Homeowners often wonder if seal coating their asphalt driveway or walkway is really necessary if the asphalt appears to be in good condition. To prolong the life of your driveway, however,seal coating maintenance is needed every three to four years. Warning Unsealed asphalt driveways or walkways will crack when water seeps underneath the surface and freezes. Ultraviolet light rays also break down the asphalt by loosening the bond between the different components of asphalt, causing your walkway to become brittle and break. Benefits Seal coating shields your asphalt from those damaging ultraviolet rays and prevents water from penetrating the asphalt. Seal coating also helps your asphalt maintain its black color. Time Frame A new asphalt driveway must be sealed within its first year, typically 90 days or longer after installation. After that, seal coat every three to four years when the old coat wears down. Tip "Ask the Builder" advises that you'll know it's time to re-do the seal coat on your asphalt when it begins to turn from all black to gray. Types There are several kinds of seal coating products, including blacktop sealer, refined coal tar sealer and acrylic polymer sealer. "Ask the Builder" recommends refined coal tar sealers for home use, since they're moderately priced and last a long time.
