THE EFFECT ON CONCRETE PAVEMENT OF STUDDED WINTER TIRES

A STUDY WAS CONDUCTED IN SWEDEN ON THE INFLUENCE OF STUDDED TIRES ON CONCRETE PAVEMENT SURFACES, INCLUDING ONE PRINCIPAL SERIES CONSISTING OF 14 DIFFERENT CONCRETE PAVEMENTS, MIXED AND PLACED ON THE TRACKS OF AN INDOOR ROAD TEST MACHINE AND ONE SUPPLEMENTARY SERIES, INCLUDING TWO CONCRETE PAVEMENT SPECIMENS TAKEN FROM ROADS OF CONSIDERABLE AGE. THE CURVES SHOWING THE AVERAGE DEPTH OF THE ABRADED WHEEL PATHS AND THE NUMBER OF WHEEL PASSAGES SHOW THAT THE WEAR RATE FOR ALL PAVEMENTS WAS RELATIVELY HIGH IN THE PRIME PHASE OF THE TESTS, BUT DECREASED LATER WHEN THE NUMBER OF COARSE AGGREGATE PIECES PROTRUDING ABOVE THE ABRADED SURFACE INCREASED. THE ENHANCED AMOUNT OF COARSE AGGREGATE RESULTED IN A VERY MARKED IMPROVEMENT OF THE ABRASION RESISTANCE. VIBRATORY PAVEMENT COMPACTION GAVE HIGHER WEAR RESISTANCE THAN HAND COMPACTION. THE CONCRETE WITH THE AIR-ENTRAINING AND WATER-REDUCING ADMIXTURE GAVE A PAVEMENT OF HIGHER DURABILITY AGAINST TRAFFIC WITH STUDDED TIRES THAN THE CONCRETE WITH AN ADMIXTURE OF MERELY AIR-ENTRAINING EFFECT. A MINIMIZED SEGREGATION ON COMPACTION RESULTS IN DECREASED ACCUMULATION OF MORTAR IN THE SURFACE AREA. SKID RESISTANCE DECREASED WHEN COARSE AGGREGATE BECAME MORE EXPOSED.
