NON-CHEMICAL METHODS OF SNOW AND ICE CONTROL ON HIGHWAY STRUCTURES

SURVEYS OF HIGHWAY CONNECTED AGENCIES AND AN EXTENSIVE LITERATURE SEARCH OF MAINTENANCE RESEARCH IN THE U. S., GREAT BRITAIN, AND EUROPE WERE CONDUCTED TO COMPILE A REVIEW OF EXISTING NONCHEMICAL METHODS OF SNOW REMOVAL AND ICE CONTROL OF CONCRETE SURFACES. DETAILS OF PERMANENT INSTALLATIONS, THE WATER PIPE AND ELECTRICAL HEATING ELEMENT CUSTOMARILY INSTALLED IN CONCRETE SLABS, ARE GIVEN. POTENTIAL APPLICATIONS OF ELECTRICAL AND GAS-FIRED INFRARED HEATERS ARE DISCUSSED. OTHER METHODS INVESTIGATED INCLUDED COVERED BRIDGES, ELECTRICALLY CONDUCTIVE ROAD SURFACES, SNOW MELTING PITS, AND BRIDGE DECK INSULATION. PERMANENT INSTALLATIONS, ALTHOUGH MORE EXPENSIVE, ARE NORMALLY MORE SUITABLE THAN PORTABLE EQUIPMENT. PORTABLE DEVICES ARE LIMITED IN THEIR ABILITY TO REMOVE SNOW, AND HAVE NOT PROVEN SATISFACTORY DURING FIELD TESTS. IN ADDITION, SNOW REMOVAL BY PORTABLE EQUIPMENT IS LIMITED TO PERIODIC MAINTENANCE, WHICH DOES NOT PROVIDE FOR SAFE AND ADEQUATE TRACTION AT ALL TIMES.
