THE POLISHING OF MINERAL AGGREGATE IN ROAD SURFACINGS /IN ENGLISH AND FINNISH/

TESTS CARRIED OUT BY USING THE ACCELERATED POLISHING MACHINE DEVELOPED BY THE ROAD RESEARCH LABORATORY, SHOWED THE POLISHED STONE VALUES OF AGGREGATE USED IN 1966 TO BE FAIRLY GOOD. THIS IS OF LITTLE IMPORTANCE IN FINLAND HOWEVER, AS THE USE OF STUDDED TIRES DURING WINTERS ROUGHENS THE SURFACE WHICH MAY HAVE BEEN SMOOTHED BY TRAFFIC DURING THE PREVIOUS SUMMERS. FROM THE TRAFFIC SAFETY POINT OF VIEW SURFACE ROUGHNESS REMAINS ABOUT THE SAME FROM YEAR TO YEAR. /RRL/
