DEVELOPMENT OF THE SAFE APPLICATION AND USAGE OF CALCIUM MAGNESIUM ACETATE AS AN ANTI-ICING AGENT UNDER NEW ZEALAND CONDITIONS

The objective of this paper is to share Transit New Zealand's (Transit's) experience of using calcium magnesium acetate (CMA) as an anti-icing agent and the results of the test program into the effect CMA has on skid resistance. The principle method of addressing ice hazards on New Zealand roads is by applying mineral grit o the road surface. However, grit build-up on the road surface tends to create its own safety hazards, and has been known to be a contributing factor in loss of control crashes. Furthermore, New Zealand motorists have become increasingly concerned about the damage loose grit on the road surface has on vehicles and windscreens, etc. Therefore, Transit decided to look at alternative methods of managing ice hazards and this paper describes the new methods.
