Porous Asphalt is an inventive road construction technology. It allows water to penetrate through the asphalt layer in the presence of air voids. This type of pavement can decrease the traffic noise and slippiness of the road surface [11].
Permeable pavement is a pavement type with a porous surface that is composed of concrete, open pore pavers or asphalt with an underlying stone reservoir. Also considered as green pavement, it allows water to run through it rather than accumulate on it or run off of it. The precipitation and water get stored in the reservoir from where it slowly …

Porous Pavement: The Cons. More expensive – in many cases a porous pavement may be more expensive to install, as it needs a specialist team using specialised equipment. The raw materials may also be more expensive – in particular, the binders. The preparation of the sub-base can also be a large part of the expense.

If a fully porous construction is desired, a porous surface course should be accompanied by an open graded binder course and by base i. Proprietary forms of surface course, designed to remain porous, are available and these are often known as 'Tennis Court Toppings'. They are based on a 6mm Porous Asphalt complying with the requirements of
Porous asphalt pavement refers to the compacted mix of modified asphalt, aggregate, and additives. C.

Porous asphalt, concrete and block paving either allow the water through the material or around the edges of the blocks, however they have to be built on a porous sub-base. Surfaces such as these are very durable and require a minimal amount of maintenance and the bonus is you will still have the look and feel of a normal paved area.
Porous Asphalt: The choker layer for porous asphalt pavement consists of 1 inch of washed No. 57 stone. PICP: The bedding layer for open-jointed pavement blocks should consist of 2 inches of washed No.8 stone. This layer is compacted after pavers are placed on it and their joints are filled with aggregate. Step 9.
