Also, NAPA offers two publications, Porous Asphalt Pavements for Stormwater Management (IS 131) and Structural Design Guidelines for Porous Asphalt Pavements (IS 140) IS 131 is a design guide that takes the reader from site design through maintenance for porous asphalt pavements, while IS 140 provides guidance on using the AASHTO 93 design.

Asphalt Products

“Asphalt for Ultra-Thin Layers (AUTL) is a hot mix asphalt road surface course laid on a bonding layer, at a nominal thickness between 10 mm and 20 mm with properties suitable for the intended use The method of bonding is an essential part of the process and the final product is a combination of the bonding system and the bituminous mixture”.
