ABSTRACT
Porous Asphalt is currently gaining in prominence in the UK after recent legislation that will help in enhancing its use to a level comparable to that in other European countries. Apart from its obvious advantages of improving safety on major roads, porous asphalt has also been found to aid in the reduction of noise levels and of vehicle operating costs. Its disadvantages have been attributed to inadequate structural support, inadequate durability and premature loss of porosity due to clogging of the voids.
