CONTROL OF ROAD SNOW AND ICE BY SALT AND ELECTRICAL ROAD HEATING

THE NORMAL TREATMENT FOR CONTROL AND REMOVAL OF SNOW AND ICE FROM ROADS IN THE UNITED KINGDOM IS THE APPLICATION OF SODIUM CHLORIDE, USUALLY IN THE FORM OF ROCK SALT. THE EFFICIENCY OF THIS METHOD DEPENDS ON WHETHER SALTING-LORRY CREWS GET INTO ACTION AT THE CORRECT MOMENT; IN ADDITION, RELIABLE ICE WARNING DEVICES ARE NEEDED. PRESENT SALTING PRACTICE AND WORK BEING DONE TO DEVELOP SUITABLE ICE WARNING EQUIPMENT IS REVIEWED. IT ALSO GIVES AN ACCOUNT OF THE DEVELOPMENT OF AN INHIBITOR TO THE CORROSION OF STEEL IN AUTOMOBILE BODIES CAUSED BY SODIUM CHLORIDE. THE COST OF THIS CORROSION IN THE UNITED KINGDOM IS MANY TIMES GREATER THAN THE COST OF ADDING A CORROSION INHIBITOR, IF A SUITABLE ONE CAN BE FOUND. A FEASIBLE, ALTHOUGH EXPENSIVE, ALTERNATIVE TO USING SALT IS TO EMPLOY ELECTRICAL ROAD HEATING. WORK DONE AT THE ROAD RESEARCH LABORATORY ON THE DESIGN AND SPECIFICATION OF THESE SYSTEMS IS PRESENTED AND ALSO SOME PRACTICAL EXPERIENCE IS GIVEN ON THEIR USE IN THE UNITED KINGDOM. /AUTHOR/
