A quality asphalt surface can last 20 years or more. However, the material is vulnerable to cold temperatures and other elements that lead to damage and require maintenance.
Proper installation by a reputable paving contractor will minimize damage, but maintenance is essential. A few easy steps can help you keep your parking lot pristine for the long haul.
Porous asphalt is a specialized paving material that allows rainwater to drain through the surface rather than being forced down a storm sewer system. This enables the soil underneath to recharge and reduces the demands on local waterways and rivers.
One challenge with porous asphalt is that the pore spaces are small. This makes it easier for dirt and other debris to clog the pavement and slow water flow, so it needs to be regularly maintained.
Another challenge is cold climates. Road salt can migrate through the porous asphalt to groundwater, causing chlorides to enter the water supply. In addition, snow plow blades can catch block edges on porous surfaces and damage the surface.
It is essential to repair asphalt cracks as soon as possible. Not only are they unsightly, but they can also cause damage to cars and be a hazard to pedestrians.
Small surface cracks should be filled with rubberized emulsion crack filler and tamped down. Larger cracks should be cut out and removed before applying asphalt crack filler.
Once the area has been cleaned and the crack filler has been tamped down, the pavement must be let dry. This can be done naturally or using a blower to speed things up.
Over time, continued exposure to sunlight dries out the oils, tar, and bitumen in asphalt, which causes it to become brittle and crack. When the cracks are filled by asphalt paving near me, it prevents further damage to the surface and extends the lifespan of your blacktop. Cracks that are left untreated can develop into their less-desirable counterparts, potholes. This type of damage is more severe and usually requires a full-depth patching method.
Asphalt stamping is a decorative paving process that transforms ordinary asphalt into a style similar to brick, slate, or stone. It requires specialized heating equipment and tough coatings but allows for limitless creativity.
The asphalt surface is heated and then stamped with a template. Acrylic-based paint coatings are applied over the asphalt to offer various color options. The result is a beautiful and durable decorative finish that can be as subtle or eye-catching as you want.
Unlike individual brick pavers, asphalt has a continuous surface that inhibits weed growth, shifting, and erosion. It is also more flexible and repairable than brick surfaces and resists cracking.
Asphalt is more economical than concrete for large parking lots, streetscapes, and residential driveways. It can be installed over existing pavement, saving on paving costs. Unlike concrete, which requires expensive maintenance procedures to prevent cracking and chipping, asphalt is more resilient and can be repaired with simple re-heating and new coatings.
Crack filling is an excellent solution for asphalt surfaces needing temporary repairs. It can fix surface cracks, alligator cracks, and potholes.
Before crack filling, the pavement should be clean, dry, and debris-free. The surface should also be aerated. Then it’s time to get ready for the crack filler to be applied. It’s best to wait until several days of clear, dry weather are predicted for the area. Rain can harm the crack filler, causing it to wash away.
When cracks are filled and seal coated, they can be preserved for the life of the pavement. This is far less expensive than rehabilitating or reconstructing a distressed road. This is why crack sealing is one of the most critical maintenance operations. It is also a great way to add value and curb appeal.
