STUDDED TIRE PAVEMENT WEAR REDUCTION AND REPAIR

THE PURPOSE OF THE PROJECT WAS FOURFOLD: TO DETERMINE PAVEMENT WEAR CAUSED BY STUDDED TIRES; TO EVALUATE THE RESISTANCE OF DIFFERENT PAVEMENT MATERIALS AND TEXTURES USED IN THE STATES OF WASHINGTON AND IDAHO TO WEAR CAUSED BY TIRE STUDS; TO TEST PAVEMENT MATERIALS AND OVERLAYS TO REDUCE TIRE STUD DAMAGE; AND TO STUDY THE EFFECT OF STUDDED TRUCK TIRES ON PAVEMENTS. THE FINDINGS INDICATE THAT SOME PAVEMENT MATERIALS ARE MORE RESISTANT TO THE EFFECT OF STUDDED TIRES THAN OTHERS. ALL TYPES OF STUDDED TIRES TESTED CAUSED SOME PAVEMENT WEAR AND THIS AFFECTED THE SKID RESISTANCE VALUES. THE NEW TYPES OF STUDS REDUCED WEAR OF VARIOUS PAVEMENT MATERIALS. STUDDED TRUCK TIRE WEAR WAS LESS THAN EXPECTED DUE TO EQUIPMENT PROBLEMS.
