Asphalt is a versatile pavement material that can be used in different circumstances and capacities including to pave roads, tennis courts, driveways, parking lots, racetracks, airport runways, and golf cart paths.
Different jobs will require different mix or type of asphalt. Mixed asphalt can accommodate different size leads, reduce splash and spray when it is raining, absorb noise and even treat water runoff. Below are some tips to help you choose the right type of asphalt for paving jobs.
Hot Mix Asphalt
This is one of the best asphalt for driveways. This is due to the fact that construction and design features are suitable and give it a finished appearance which complements the home. It is easy to repair, strong and durable, withstands freezing and thawing, relatively inexpensive, is not affected by salt in the winter and requires low maintenance.
Warm Mix Asphalt
Warm mix asphalt uses technologies which enable the asphalt paving at significantly lower temperatures. This reduces greenhouse gases, saves fuel and extends the paving season. It also enables better compaction of paving when laid.
Porous asphalt enables water to drain through the surface and into a recharge bed before draining into the soil below the pavement.
This pavement is mostly used for parking lots as it enhances the management of storm water and also improves the quality of ground water. Just like the other types of asphalts, porous asphalt is designed for different situations and circumstances.
Noise pollution is one of the most intrusive types of pollution. Stone mix asphalt can help reduce road noise by about 50%. This is a cost-effective and more practical solution than noise barrier walls. This is ideal for roads built through existing residential communities and homeowners are forced to adapt to the noise.
Perpetual pavement is based on a multi-layer paving process to help prolong the lifespan of roadways. The base is strong and flexible to prevent cracks in the bottom of the pavement, a strong permanent middle layer is added and a driving surface that will last for many years will also be added.
The driving surface is replaced periodically. Only the top layer is usually removed and replaced hence reducing the work time and long term costs significantly. Besides, asphalt is recyclable meaning it will reduce the cost and also help preserve the environment.
With the advancement in technology, more and more types of asphalt will continue being discovered in future. The more the types of asphalts, the better the options to choose from.
