Abstract

The effects of the de-icing agent Calcium Magnesium Acetate (CMA) on the magnitude and duration of skid resistance changes of a range of road surface types were examined through an on-road test programme on New Zealand state highways, during the winter of 2004. This involved a baseline survey of skid resistance on sites were CMA had been used in previous years, followed by a more focused series of skid resistance measurements made with different skid testers. These skid testers included an instrumented car, the British Pendulum Tester, and the GripTester. Tests were conducted under various conditions, with and without CMA. Road surface types included fine and coarse chipseal, open graded porous asphalt (OGPA), asphaltic concrete and slurry seal. Comparisons were made between the different skid testers for the different surfaces, and different road surface conditions, both with and without CMA. Some potential implications for management of the use of CMA were examined. (Author/publisher)
