Four Areas of Asphalt Maintenance

When looking at asphalt maintenance it can be divided into four areas. The primary cause of asphalt failing is the penetration of water into the asphalt base. Overtime, it will become brittle and dry with the aggregate beginning to wear away and cause cracks that will let water penetrate into the base of the pavement. When the water seeps into the crack it causes the base material to move and settle. This leads to the surface cracking in a pattern that is grid-like When the payment has reached this stage there are only two options, which are replace the old asphalt or patch repair it.

Patch repair

It deals with areas that are isolated. Using a backhoe and saw-cutting the pavement is removed. They can also use a grinding machine. Once the old asphalt is removed, it is replaced with new asphalt. The removal method determines the amount that is removed. The removal depth should be equal to one point five times the original thickness of the asphalt. You may also have to replace the base-rock to match the adjacent areas to allow for a base support that is uniform. The amount of removal should be extended twelve inches past the area that failed.

Asphalt overlay

This asphalt maintenance is affordable and provides a new wearing surface. When dealing with asphalt overlay there are certain factor you need to be aware of, which include:

• Overlay thickness-it should be a maximum of two point five inches with a minimum of one point five inches
• Smooth transitions-when you are considering where to grind the existing pavement down remember not to grind down the overlay section to match the existing structure. If you do this could weaken the overlays strength. They will grind the existing payment down to where they meet flush together to prevent this.

Inlay and pulverize in place

Both of these areas of asphalt maintenance are accomplished using a milling machine. During the process of inlay, it removes a depth of the existing asphalt, which is many times a previous overlay. This will let the contractors to put the asphalt back to the pre-inlay elevation. The method of pulverize-in-place will reduce all of the asphalt to particles that are base-rock size.

Seal coating

This is an important part for extending the life of the asphalt and it should not be overlooked. Seal coating is a mixture of mineral fibers, emulsified asphalt, and water along with other admixtures. This will seal the top layer of asphalt to prevent water from penetrating the pavement surface and protecting the top layer from wear from sun exposure and oxidation. It is what gives the asphalt its even black surface.

Porous Paving: An Attractive and Environmentally Friendly Alternative

Installing a new pavement around your home is an easy but effective way to increase the aesthetics of your house’s outside spaces and boost its property value. There’s a certain atmosphere of charm in a home with an attractive pavement-whether it’s made of cobblestone or flat rock. After all, nothing says old world suburban charm than a rocky pavement.

But have you considered the other pavement options available out there? Beyond the usual cobblestone and brick pavement, there’s also porous permeable pavement. It’s an equally attractive alternative to spruce up your hardscapes, and it comes with multiple innate properties that traditional pavement doesn’t have.

Porous Permeable Pavement

As its name suggests, porous pavement has small holes as part of its overall composition. While this might seem like it weakens the pavement, it actually does the contrary. One of the main draws of porous pavement is that the small holes provide a way of ‘naturally’ letting water drain through the pavement and directly to the soil.

The benefit is pretty obvious; while stone pavements are strong, they are not indestructible and can easily be weathered down through exposure to water for example. This also makes it relatively low maintenance, since there’s not that much water that needs clearing.

Beyond innate surface water management, it also reduces the amount of irrigation you need to do. This is especially true if you’ll be setting the pavement down on your garden. Because of its porous nature, the water goes through the soil really easily. This prevents unsightly and uneven grass and terrain. You’ll also be cutting back on your water usage, which is great for your wallet as well as for the environment. Basically, you’re going Green!

Finally, porous pavement is aesthetically very attractive to look at. It comes in a variety of styles and colours and prices, ranging from the traditional light asphalt to sand-coloured resin pavement.

A Green Alternative

Porous pavement is a green alternative. As mentioned before, its porous nature allows rain to penetrate the surface and flow beneath the ground naturally, and more importantly, can be instrumental in preventing dangerous flooding.

The reduction of storm system basins isn’t the only reason this type of paving is green. Porous pavement actually requires less energy to manufacture, which means less emissions, odour and smoke. It’s attractive and environmentally friendly – both during its manufacturing process and installation.
