STEEL REINFORCED ASPHALT OVERLAY

THE WISCONSIN STATE HIGHWAY COMMISSION HAS RESURFACED ABOUT 1 1/2 MILE OF OLD TWO-LAND CARRIAGEWAY WITH A 3-IN OVERLAY OF BITUMINOUS SURFACING REINFORCED WITH WELDED WIRE FABRIC, AS AN EXPERIMENT, ON AN OLD FLEXIBLE PAVEMENT WHICH HAD HEAVED AND FAULTED. THE NEW SURFACING WAS LAID IN TWO 1 1/2-IN COURSES WITH THE REINFORCEMENT IN BETWEEN, THE TRANSVERSE WIRE BEING IN CONTACT WITH THE UPPER SURFACE OF THE LOWER COURSE. THE REINFORCING MESH SHEETS WERE PLACED 3 IN FROM THE EDGE OF THE LOWER COURSE OF ONE LANE, EXTENDING TO 9 IN BEYOND THE CARRIAGEWAY CENTRE-LINE. NARROWER SHEETS WERE USED FOR THE SECOND LANE AND BUTTED ON TO THE SHEETS ALREADY LAID. CURLING OF THE MESH AT THE CENTER-LINE WAS OVERCOME BY BENDING THE SHEET ABOUT A FOOT FROM ITS EDGE. /RRL/
