INVESTIGATION OF POROUS PAVEMENTS FOR URBAN RUNOFF CONTROL

LABORATORY STUDIES DEMONSTRATED THE TECHNOLOGICAL AND ECONOMIC FEASIBILITY OF OPEN-GRADED ASPHALT CONCRETE AS POROUS PAVEMENTS TO CONSERVE WATER, TO REDUCE LOADS ON COMBINED SEWERS AND TREATMENT PLANTS, AND TO MITIGATE URBAN RUNOFF AS A DESTRUCTIVE ENVIRONMENTAL FACTOR. LABORATORY STUDIES OF CANDIDATE MATERIALS REVEALED A POROUS ASPHALTIC CONCRETE CONTAINING 5.5% ASPHALT BY WEIGHT AND AGGREGATE GRADED TO ALLOW A WATER FLOW OF 76" PER HOUR TO BE THE OPTIMAL POROUS ROAD MATERIAL. MATERIALS TESTING FOR STABILITY, DURABILITY, AND FREEZE-THAW SUSCEPTIBILITY PROVED THIS MATERIAL SUITABLE FOR USE IN ROAD CONSTRUCTION. MAJOR DESIGN PARAMETERS CONSIDERED WERE THE LOAD-BEARING CAPACITY AND PERMEABILITY OF THE SUBGRADE, EXPECTED MAXIMUM PRECIPITATION AND DEPTH OF FROST PENETRATION.
