INFLUENCE OF FACTORS ON THE WEAR CAUSED BY STUDDED PASSENGER CAR TIRES ON PAVEMENT OF DENSE ASPHALT CONCRETE HAB 16. A FACTORIAL STUDY WITH THE INSTITUTE'S ROAD SIMULATOR
A test run was carried out in a traffic simulator to study the influence of certain factors (content of particles of 8-17 mm; particle size distribution between 0.074 and 8 mm; filler quality; content of filler; content of bitumen; and compaction) on the wear caused by studded automobile tires on pavement of dense asphalt concrete HAb 16 (maximum particle size=16 mm). The results of the study indicate that the wear is reduced: by 15% when the content of particles 8-16 mm is increased from 30% to 45% and by an additional 15% when the content of the same particles is increased to 60%; by about 10% when the filler content is increased from 9% to 13%; and by about 10% by a certain change in particle size distribution. The results also show that resistance to studded tires is not directly influenced by a pavement richer in bitumen, and that the resistance is not influenced by filler quality.
