Asphalt Driveway Maintenance in Spring Season
Excerpt from Article on Thedailynewsonline.com
Read Full Post | Make a Comment ( None so far )Angie’s List, a Web site of consumer reviews on service companies, went to driveway sealing and repair experts for tips on keeping your driveway in top shape.
“The best way to protect your investment in your driveway is by sealing it every two to five years, depending on its condition,” said Angie’s List founder Angie Hicks. “That can help prevent staining, enhance its appearance and extend its lifespan.”
Asphalt driveways typically require more maintenance than concrete drives, but are less expensive to install and easier to repair. However, natural elements, such assun and rain, take a toll on asphalt driveways.
Cracks and holes can be filled and repaired more easily with asphalt, whereas damaged sections of concrete driveways typically must be replaced instead of repaired. Concrete drives can hold more weight, however, and offer more variety, including stamped patterns and different colors.

By: John Wentz
Since the days of ancient Rome there have been covered access chambers for utilities. In ancient Rome there were sewer grates that covered sewers while still allowing access to those that needed it. Modern asphalt manholes (also known as a maintenance holes, utility holes, inspection chambers or access chambers) is the top opening to an underground utility vault that serves as an access point for connecting or performing maintenance on underground utilities and other services such as sewers, telephone, electricity, storm drains and gas lines.
The top of the manhole is protected by a manhole cover (sometimes known as a biscuit or casting), a plug designed to prevent unauthorized access to the manhole. Manhole covers usually weigh more than 100 pounds (roughly 50 kg), partly because the weight keeps them in place when traffic passes over them, and partly because they are often made out of cast iron, sometimes with infills of concrete. This makes them inexpensive and strong but heavy. A manhole cover sits on metal base, with a smaller inset rim which fits the cover.
Manhole covers usually feature “pick holes,” in which a hook handle is inserted to lift them. Pick holes can be concealed for a more watertight lid, or can allow light to shine through. A manhole pick or hook is typically used to lift them, though other tools can be used as well.
Because of the variety of materials involved in manhole construction, asphalt manhole repair works best using polyurethane asphalt repair material . Cold mix or hot mix can be used but will not last because manholes often have asphalt and concrete and the asphalt repair materials will not bind to the metal.
Because of the uneven surfaces, water tends to collect around a manhole cover, so in order to promote adhesion, use a butane torch on the surface to dry it completely. Surround manhole with polyethylene to prevent anything from entering the hole or from sticking to the cover. If there is no plastic available, use masking tape.
Using polyurethane asphalt repair product, simply mix your materials and trowel it on. When repair is sufficiently smooth, toss topping sand by hand over repaired area to create a uniform look and feel. Your asphalt manhole can be ready for traffic in about an hour.
If there are any surrounding cracks or alligatored area, those should be filled in at the same time to prevent further breakdown. To fill the cracks, polyurethane crack repair material can be used to fill the cracks quickly and efficiently.
