USE OF INSULATING LAYER TO ATTENUATE FROST ACTION IN HIGHWAY PAVEMENTS

CONVENTIONAL METHODS OF TREATING THE DETRIMENTAL EFFECTS OF FROST ACTION ARE AIMED AT REPLACING OR ALTERING THE FROST -SUSCEPTIBLE SOILS AND/OR CONTROLLING THE WATER SUPPLY. THE USE OF A STYROFOAM INSULATING LAYER TO ATTENUATE FROST ACTION TO REDUCE THE EFFECT OF THE FREEZING TEMPERATURES HAS BEEN UNDER STUDY FOR THE PAST 5 YR. STYROFOAM INSULATING LAYERS HAVE SHOWN PROMISING RESULTS UNDER TEST IN A NEW FLEXIBLE PAVEMENT AT MIDLAND, MICH., IN A NEW RIGID PAVEMENT NEAR WEST UNION, IOWA, AND IN A MAINTENANCE TREATMENT OF SEVERE FROST HEAVE IN FLEXIBLE PAVEMENT NEAR MINNEAPOLIS, MINN. A RELATIVELY SMOOTH SUBGRADE SURFACE IS REQUIRED ON WHICH TO PLACE THE STYROFOAM BOARDS, AND AN 8-IN. THICK LIFT OF GRANULAR MATERIAL PLACED OVER THE STYROFOAM WILL SUPPORT CONSTRUCTION TRAFFIC. /AUTHOR/
