EVALUATION OF CONCRETE CURBING

OWING TO THE CLOSING OF MOST OF MAINE'S GRANITE QUARRIES, WHICH HAD BEEN THE PRINCIPAL SOURCE OF CURBING, RESEARCH WAS UNDERTAKEN INTO THE USE OF TWO TYPES OF PCC---CAST-IN-PLACE AND PRECAST---WITH AND WITHOUT COATINGS (PG-1024 AND THIOPOXY 61) AS A SUBSTITUTE. THE THREE MAJOR CRITERIA FOR EVALUATION WERE APPEARANCE, DAMAGE, AND SAFETY. QUARTERLY RATINGS WERE MADE FROM SUMMER 1966 THROUGH LATE SPRING 1971. THE TWO CONCRETES EXHIBITED NO SIGNIFICANT DIFFERENCES IN DURABILITY, NOR DID COATINGS HAVE AN EFFECT; HOWEVER, AFTER BEING DAMAGED THE COATINGS LENT A MUCH WORSE APPEARANCE TO THE CURBINGS. IN ALL RESPECTS CONCRETE WAS FOUND INFERIOR TO GRANITE, AND IT IS RECOMMENDED THAT PCC NOT BE USED IN SUBSTITUTION OF GRANITE IN MAINE.
