STUDY OF EFFECTS OF GROOVING ON PAVEMENT DETERIORATION INSPECTION OF GROOVED AIRFIELD PAVEMENTS

A STUDY WAS MADE ON THE DETERIORATION EFFECTS OF DELIBERATE GROOVING ON AIRFIELD PAVEMENTS. GROOVING IS DONE TO REDUCE HYDROPLANING AND SKIDDING. GROOVED PAVEMENTS WERE INSPECTED AT FOUR CIVILIAN AND ONE MILITARY AIRFIELD. THE INSPECTION INCLUDED PORTLAND CEMENT CONCRETE (PCC) RUNWAYS AT FOUR AIRFIELDS AND ASPHALTIC CONCRETE (AC) RUNWAYS AT TWO AIRFIELDS, ALL OF WHICH HAD BEEN GROOVED WITHIN 2 YEARS BEFORE THE INSPECTION. GROOVES IN ALL PCC RUNWAYS WERE IN EXCELLENT CONDITION WITH NO EVIDENCE OF DETERIORATION EXCEPT IN ONE CASE WHERE NUMEROUS SMALL POPOUTS AND WEATHEROUTS HAVE OCCURRED. GROOVING HAD APPARENTLY CONTRIBUTED TO AN INCREASE IN THESE DEFECTS. THE AC RUNWAYS SHOWED MINOR GROOVE DETERIORATION IN SOME AREAS, AND SOME OBLITERATION OF THE GROOVES IN ONE TOUCHDOWN AREA. RUBBER DEPOSITS IN GROOVES HAVE OCCURRED IN BOTH PCC AND AC PAVEMENTS, BUT NO REMOVAL OF THE RUBBER HAS BEEN REQUIRED. GROOVING HAS NOT AT PRESENT RESULTED IN ANY SIGNIFICANT DETERIORATION OF EITHER PCC OR AC RUNWAY PAVEMENTS. SOME CLOSING OF GROOVES IN TOUCHDOWN AREAS OF AC SURFACES CAN BE EXPECTED, BUT THIS IS NOT CONSIDERED TO BE ACTUAL PAVEMENT DETERIORATION. WHERE PCC PAVEMENTS HAVE PREVIOUS POPOUTS OR OTHER SURFACE DEFECTS, GROOVING CAN BE EXPECTED TO INCREASE THESE DEFECTS. PCC AND AC RUNWAY PAVEMENTS SHOULD CONTINUE TO BE INSPECTED PERIODICALLY TO DETERMINE THE LONG-TIME EFFECTS OF GROOVING. /AUTHOR/
