WIRE MESH REINFORCEMENT OF BITUMINOUS OVERLAYS

RESULTS ARE PRESENTED OF AN INVESTIGATION INITIATED TO EVALUATE THE EFFECTIVENESS OF WELDED WIRE MESH IN PREVENTING OR RETARDING REFLECTION CRACKING IN ASPHALTIC SURFACE COURSES OF COMPOSITE PAVEMENTS AND IN ASPHALTIC OVERLAYS OF OLD CONCRETE PAVEMENTS. THE EFFECTIVENESS OF THE MESH WAS EVALUATED IN TERMS OF THE PERCENT OF UNDERLYING JOINTS OR CRACKS WHICH REFLECTED THROUGH COMPARATIVE REINFORCED AND PLAIN OVERLAYS. INSTALLATIONS OF WIRE MESH IN THE OVERLAYS OF THREE GROUPS OF PAVEMENTS WERE INVESTIGATED' /1/ FOUR NEW COMPOSITE PAVEMENTS IN WHICH 5-FT WIDE MESH STRIPS WERE PLACED OVER THE LONGITUDINAL AND CONSTRUCTION JOINTS OF THEIR CONTINUOUSLY CONSTRUCTED PLAIN CONCRETE BASES, /2/ FOUR OLD CONCRETE PAVEMENTS IN WHICH 5 OR 8-FT WIDE MESH STRIPS WERE PLACED OVER THE LONGITUDINAL JOINTS FORMED BY THE OLD PAVEMENTS AND WIDENING STRIPS, AND /3/ FIVE OLD CONCRETE PAVEMENTS IN WHICH MESH STRIPS OF DIFFERENT WIDTHS AND STYLES WERE PLACED OVER THE TRANSVERSE EXPANSION JOINTS OF SELECTED SECTIONS. THESE INSTALLATIONS WERE OBSERVED OVER SERVICE PERIODS RANGING FROM TWO TO TEN YEARS AND THE FOLLOWING CONCLUSIONS DRAWN' /1/ WIRE-MESH STRIPS WERE INEFFECTIVE IN PREVENTING REFLECTION CRACKING IN COMPOSITE PAVEMENTS AND MAY HAVE CONTRIBUTED TO MULTIPLE CRACKING OF THE ASPHALTIC SURFACING, /2/ WIRE-MESH DID NOT PREVENT REFLECTION CRACKING OF LONGITUDINAL JOINT ASSOCIATED WITH THE WIDENING OF OLD PAVEMENTS, AND /3/ WIRE-MESH STRIPS TENDED TO RETARD THE DEVELOPMENT OF REFLECTION CRACKING OVER TRANSVERSE EXPANSION JOINTS SPACED AT 80 FEET OR LESS IN OLD CONCRETE PAVEMENTS.
