POROUS PAVEMENT AIDS IN THE CONSTRUCTION OF AN "ECOLOGICAL" PARKING LOT

THE UNIVERSITY OF DELAWARE, LOCATED IN NEWARK, IS NOW THE OWNER OF WHAT IS REPORTEDLY THE FIRST APPLICATION IN THE AREA OF A POROUS BITUMINOUS PAVEMENT, IN THE FORM OF A 140-FOOT X 240-FOOT PARKING LOT. IT IS THE INITIAL FIELD APPLICATION OF A MIX DESIGNED BY A DEVELOPMENT TEAM AT FRANKLIN INSTITUTE IN PHILADELPHIA TO ALLOW RAINWATER TO PERMEATE THROUGH THE TWO-AND-ONE-HALF-INCH MAT, RETURNING THE FLOW TO THE GROUNDWATER TABLE AND RELIEVING STORM SEWER LINES. THE MIX UTILIZED A PRE-COATED STONE TO INSURE AN OPEN-GRADE FOR SEEPAGE OF WATER, INTO THE STONE BASE AND FINALLY INTO THE SUBGRADE. PUT DOWN IN 10-FOOT WIDE PASSES, THE ONLY MINOR PROBLEM ENCOUNTERED WAS KEEPING THE GRADE SHAPED IN FRONT OF THE PAVER SINCE THERE WAS NO COMPACTION PRIOR TO PAVING. APPROXIMATELY 375 TONS OF MIX WERE PLACED IN ORDER TO GIVE THE FINAL TWO-AND-ONE-HALF INCH (COMPACTED) POROUS SURFACE. /DOT/
