INFLUENCE OF METEOROLOGIC FACTORS ON FROST DAMAGE IN ROADS

RELATIONSHIPS OF WEATHER PATTERNS AND FROST DAMAGE MAKE IT POSSIBLE FOR THE DEPARTMENT OF ROADS TO HAVE AN IDEA OF HOW EXTENSIVE NECESSARY TRAFFIC RESTRICTIONS WILL BE, TO MAKE CORRESPONDING PREPARATION, AND TO PLAN MEASURES FOR MEASURES FOR MAINTENANCE AND RESTORATION OF THE ROADS. THE INVESTIGATION OF THE DECISIVE WEATHER FACTORS OF PRECIPITAT- ION AND RESULTING GROUND MOISTURE AND THE TEMPERATURE PATTERN, PRODUCED THE FOLLOWING' /1/ THE PRECIPITATION BEFORE FREEZING, DURING INTERVENING THAW PERIODS, AND DURING THE FINAL SPRING THAW, HAS NO INFLUENCE ON THE DEGREE OF FROST ENDANGERING, /2/ THE MOISTURE CONTENTS OF FROST- SUSCEPTIBLE SUBSOILS BEFORE THE START OF THE FROST PERIODS ARE DIFFERENT FOR VARIOUS SOIL TYPES BUT ARE NEARLY EQUAL EACH YEAR FOR INDIVIDUAL SOILS, /3/ A CONNECTION WAS ESTABLISHED BETWEEN TEMPERATURE PATTERN AND DEGREE OF FROST ENDANGERING, /4/ FROST HEAVE DAMAGE CONSTITUTES ONLY A SMALL PART OF THE TOTAL FROST DAMAGE BECAUSE MORE PREDOMINANT FAILURES ARE CAUSED BY TRAFFIC DURING THE THAW, /5/ A CRITERION WAS DEVELOPED BY MEANS OF WHICH THE DEGREE OF FROST ENDANGERING DURING THE THAW CAN BE PREDICTED ACCORDING TO THE TEMPERATURE PATTERN, /6/ DELIBERATIONS ABOUT THE INFLUENCE OF WEATHER PATTERNS PRODUCED SOME CONCLUSIONS ABOUT FROSTPROOFING MEASURES IN NEW ROAD CONSTRUCTION AND IMPROVEMENT OF OLD ROADS.
