INTRODUCTION • The transport demand increase by over 5 times by the year 2021. • As per the study conducted by MORT&H, 15,766 km of Expressway is required by the end of year 2020. • Need to maintain the speed on these expressways, which gives good skid resistance and …
porous asphalt pavement design are: WATER QUALITY . Porous pavements are highly effective in reducing pollution in stormwater runoff from pavements. Cahill reports that, although sam- pling on porous pavement systems has been limited, the available data indicate a high removal rate for total suspended solids (TSS), metals, and oil and grease.

Porous asphalt pavements allow for land development plans that are more thoughtful, harmonious with natural processes, and sustainable. They conserve water, reduce runoff, and promote infiltration, which cleanses stormwater, replenishes aquifers, and protects streams. Porous asphalt pavements are being used successfully throughout the United ...

Aug 25, 2014· Porous asphalt pavements offer developers and planners a new tool in their toolbox for managing storm water. These pavements, used mostly for parking lots, allow water to drain through the pavement surface into a stone recharge bed and infiltrate into the soils below the pavement. Such pavements have been proving their worth since the mid-1970s ...

This guidance considers Pervious Concrete Pavement (PCP), Pervious Asphalt Pavement (PAP) (also known nationally as Porous Asphalt Pavement), and Permeable Interlocking Concrete Pavement (PICP). While pervious pavements have become very popular in the area of stormwater management, the true applicability to the highway environment is still unclear.

Porous asphalt is open-graded asphalt mixed with less sand and fine particles than conventional asphalt and is laid above crushed stone aggregate layer to allow for water infiltration, making it a Stormwater Management best practice by the US EPA. Water is able to permeate the asphalt due to increased void space of (approx. 16% compared to 2-3% for conventional asphalt).

Porous asphalt is an environmentally friendly tool for stormwater management. POROUS ASPHALT PAVEMENTS In the natural environment, rainfall sinks into soil, filters through it, and eventually finds its way to streams, ponds, lakes, and underground aquifers. The built environment, by way of contrast, seals the surface. Rainwater and
