STUDIES OF PAVEMENT WEAR CAUSED BY STUDDED PASSENGER CAR TYRES ON STRAIGHT TEST TRACKS, THE "BROMMA TRACK"
A test track composed of eight straight test sections with different wearing courses was built on the domestic airport of Stockholm (Bromma Airport) during the autumn of 1968, and it was trafficked by an autopiloted wehicle provided with four studded tyres. The purpose was to determine the wear of different pavements caused by studded tyres under realistic conditions and to establish the relation between such wear and the wear measured in similar experiments in the road machine of the Road Research Institute. The tests were carried out during two winters, comprising in all 100,000 circuits. The wear was measured by geometric profiling, and on the same time a method based upon the measurement of radioactive radiation absorption was tried. The results showed the same ranking of the different pavements with respect to wear on the Bromma test track as in the road machine. They also showed that the wear resistance is favored by enrichment of large aggregate, especially in the surface, of the wearing course, by increased binder hardness and by tar precoating of the aggregate at high temperature. Teh manufacture of wearing courses including rolled-in coated chippings has some critical stages which can easily make the addition of the chippings useless. One small sample from an old Portland cement concrete pavement was also included and showed comparatively little wear.
