Evaluating Clogging in Porous Pavement Systems
(2007 – current)
In Australia, porous pavements are rarely used, mainly due to perceptions that they are prone to clogging. This laboratory based project looks at the effectiveness of 3 common types of porous pavements in reducing stormwater volume and improving outflow stormwater quality. This research will feed into the project Could Porous Pavements be Part of the Urban Water Solution?
The three pavement types are the traditional monolithic porous asphalt, the popular modular Hydrapave (known as Formpave in the UK), and Permapave, a new type of monolithic pavement developed in Australia. These systems have been compared to deliver new insights into the nature of clogging in porous pavements and consequently, the treatment performance of these systems under Australian conditions. This was achieved by simulating dry and wet weather periods under typical Melbourne and Brisbane climate conditions. Recommendations regarding the porous pavement design will also be developed.
