REFLECTION CRACKING N BITUMINOUS OVERLAYS

NINE DIFFERENT TREATMENTS TO THE PAVEMENT WERE INCLUDED IN THE DESIGN OF AN INTERSTATE PROJECT IN COLORADO TO FIND A METHOD OF REDUCING OR ELIMINATING REFLECTION CRACKING THROUGH BITUMINOUS OVERLAYS. EACH TREATMENT IS REPRESENTED BY TWO 1,000-FOOT-LONG SECTIONS; TWO STANDARD SECTIONS WILL BE USED AS A BASIS FOR COMPARISONS. THE NONE TREATMENTS USED TO REDUCE REFLECTIVE CRACKING ARE: (1) ASPHALT REJUVENATING AGENT; (2) POLYPROPYLENE FABRIC; (3) ASPHALT EMULSION SLURRY; (4) SQUEEGEE SEAL; (5) HEATER BLADE SACRIFIER, (6) PLANT MIX SEAL; (7) HAND POURED CRACK FILLING; (8) RUBBERIZED ASPHALT CEMENT; AND (9) RUBBER EMULSION. PRE-AND-POST CONSTRUCTION EVALUATIONS AS WELL AS DESCRIPTION OF THE CONSTRUCTION METODS ARE INCLUDED. ON COMPLETION OF THIS STUDY, THE MOST FAVORABLE SYSTEM FOR REDUCING REFLECTIVE CRACKING CAN BE IMMEDIATELY IMPLEMENTABLE. /FHWA/
