Porous Asphalt

What are Porous Pavers

Pavers are building substances which are used to pave areas. And among those pavers a particular type is porous pavers which are nothing but pavers having tiny holes in them. These holes are useful in order to drain out runoff water or rain water. There are few porous pavers which have open grids. You can plant different types of vegetation and grasses in those grids. The regular kinds of pavers are known for reflecting heat and thus rising temperature. But porous pavers are eco—friendly because of their ability of absorbing heat. Thus they actually lower the rising temperature. And they also filter as well as cool the water which they drain out.

Three types of porous pavers

There are various kinds of porous pavers available in the market. Among them three major types are—porous concrete, porous stone pavers and of course porous asphalt pavers. All three of these pavers are sturdy enough which further makes them capable to stand heavy horizontal, vertical and rotational loads.

 

What is porous asphalt

As we have already known that porous asphalt is a particular type of porous pavers, it is more or less same as any other asphalt pavers. The main difference between any kind of asphalt pavers and a porous one is that the later one is mixed keeping the smallest aggregate away. In the general type of asphalt pavers the small aggregate makes its place into the tiniest cracks and gaps of the asphalt. Therefore it seals the asphalt and water can not penetrate it. If those small components are excluded the water can easily drain into the porous asphalt and can make its way out too. This prevents the pooling of water. For this attribute porous asphalt is popular in constructing roads. Roads constructed by porous asphalt are quite safe for traffic during the snow and rain.

 

Where is porous asphalt used

Porous asphalts are used in building driveways, parking lots, pathways and busy lanes. This type of pavers is used along the embankments and river sides. There it is used as an effective method of preventing soil erosion. Porous asphalt is an excellent eco—friendly option for landscaping because it provides ground cover that can be planted in those areas which might have looked wasted and bare otherwise. Porous asphalt can also be placed around plants and trees as it does not affect the growth of the plants.

 

Installing porous asphalt

The installation of these pavers is quite simple. The primary thing one needs to remember while doing so is to make sure the presence of a proper base under the porous asphalt pavers. Being porous this asphalt is capable of draining water quickly, so the soil under it has to have the same ability. If the base is not capable of draining water then porous asphalt will be of no use.

 

How to clean

It is easy to clean these pavers by regular street cleaning devices, i.e. either a vacuum or a sweep.
