COLORED PAVEMENT HAS SOME BIG UNSOLVED PROBLEMS

COLORED STANDARDS AS WELL AS SPECIFICATIONS ARE NEEDED BEFORE COLORED CONCRETE PAVEMENT CAN BE UNIVERSALLY ACCEPTED. THE COST OF COLORED PAVEMENT OF SYNTHETIC RESIN IS MUCH GREATER THAN THAT OF COLORED PORTLAND CEMENT CONCRETE. COLORED PORTLAND CEMENT CONCRETE AVERAGES ONLY EIGHT DOLLARS A TON MORE THAN STANDARD CONCRETE. PIGMENTS ARE READILY AVAILABLE FOR CONCRETE, HOWEVER, SYNTHETIC RESINS REQUIRE MIXING OF A PIGMENT AND BINDER. CLEANLINESS IS THE KEY TO LAYING HOT-MIX COLORED PAVEMENT. THE PUG MILL AND THE PAVER MUST BE CLEANED BY SPRAYING AND RUNNING SEVERAL TONS OF CLEAN, DRY AGGREGATE THROUGH IT. THE TEMPERATURE IS ALSO IMPORTANT WHEN LAYING COLORED PAVEMENT. THE ROLLER MUST BE RIGHT BEHIND THE PAVER. PROBLEMS OF FADING ARE DISCUSSED AND COLORED AGGREGATE IS RECOMMENDED AS A SOLUTION. IN ADDITION TO FADING, COLORED PAVEMENT IS OBLITERATED BY SNOW, LOOKS BLACK OR WHITE WHEN WET AND AT NIGHT. HOWEVER, FOR EFFECTIVE TRAFFIC CONTROL, COLORED PAVEMENT IS STILL RECOMMENDED.
