THE INFLUENCE OF TOPOGRAPHY ON THE DURATION OF ICE-FORMING CONDITIONS ON A ROAD SURFACE

STUDIES WERE MADE OF THE CLIMATIC AND ROAD SURFACE CONDITIONS AT SIX SITES ON HIGHWAYS IN SCOTLAND. IT WAS FOUND THAT THE TOPOGRAPHIC ENVIRONMENT MOST LIKELY TO FAVOUR ICE-FORMING CONDITIONS IS ONE IN WHICH THE ROAD IS SCREENED FROM THE SUN; THE MORE EXTENSIVE THE SCREENING, THE GREATER THE POTENTIAL DANGER. THE THEORETICAL RATE OF EVAPORATION OF WATER VARIED INVERSELY WITH THE TOTAL DURATION OF ICE-FORMING CONDITIONS AT EACH SITE. /HSL/
