PAVEBRITE COLORED PAVEMENT INSTALLATION ON THE SUNSHINE STATE PARKWAY
SKID TESTS WERE PERFORMED TO DETERMINE THE EFFECTIVENESS OF PAVEBRITE COLORED PAVEMENT TO CHANNELIZE TRAFFIC SAFELY. PAVEBRITE IS A BINDER USED IN PLACE OF ASPHALT CEMENT FOR FLEXIBLE PAVEMENT SURFACE COURSES. THE BINDER IS CAPABLE OF BEING MIXED WITH PIGMENTS TO PRODUCE A VARIETY OF COLORS. ALL OF THE TEST INSTALLATIONS WERE IN DECELERATION LANES OF THE INTERCHANGES. THE EXISTING ASPHALT CONCRETE SURFACE WAS PREPARED BY APPLYING A SCRATCH COAT OF TYPE 1 ASPHALTIC CONCRETE WITH A THICKNESS OF APPROXIMATELY ONE QUARTER OF AN INCH TO PROVIDE A BOND BETWEEN THE EXISTING PAVEMENT AND THE COLORED MATERIAL. THE COLORED MATERIAL CONSISTED OF A 1/2 INCH THICK ORANGE COLORED SURFACE. ALL CONSTRUCTION JOINTS WERE CUT WITH A CONCRETE SAW AND PAINTED WITH AN EPOXY BONDING AGENT AND THE AREA TO BE SURFACED WAS ALSO LIGHTLY TACKED WITH THE BONDING AGENT. RAPID COOLING OF THE MIX MUST BE PREVENTED WHILE THE MIX IS BEING PLACED. IT WAS DETERMINED THAT AN EXCEPTIONALLY HOT SCREED PRODUCED A BETTER TEXTURED MAT, AND THAN CLEAN EQUIPMENT IS REQUIRED TO PREVENT COLOR CONTAMINATION IN THE PAVEMENT. HIGH SKID RESISTANCE OBSERVED ON THOSE TESTS IS ATTRIBUTED TO THE MATRIX (SYNTHETIC RESINS) CHARACTERISTICS RATHER THAN THAT OF THE AGGREGATE. IT IS COMMENTED THAT COLORED PAVEMENT ALONE MAY NOT BE SUFFICIENT TO CHANNELIZE TRAFFIC AND THAT IT SHOULD ALSO BE STRIPED.
