EVALUATION OF VERGLIMIT (A DE-ICING ADDITIVE IN PLANT MIXED BITUMINOUS SURFACE). FINAL REPORT

The proprietary product Verglimit claims to decrease the amount of materials and man-hours needed for snow and ice control while maintaining adequate safety levels. Verglimit consists of calcium chloride flakes encapsulated in linseed oil which are blended into the plant-mixed bituminous wearing surface. The manufacturer claims that exposed CaCl will attract moisture and form a solution which prohibits adhesion of snow and ice to the pavement. A Verglimit test section was constructed on U.S. Route 8 near Taylors Falls, Minnesota. The applied mix appeared to be tender and some compaction difficulties were experienced. Manufacturer's recommendations were closely followed and no other unexpected difficulties occurred. Evaluation of the test section consisted of deicing observations as well as other pavement performance characterizations. Portions of the Verglimit overlay experienced shoving and were milled and replaced. Significant deicing benefits were not obserced. No future Verglimit sections are planned.
