• Abstract:
  One of the challenges that faces the winter maintainer is how much chemical to ; apply to the road under given conditions. Insufficient chemical can lead to the road ; surface becoming slick, and the road thus becoming unsafe. In all likelihood, additional ; applications will have to be made, requiring additional effort and use of resources. ; However, too much chemical can also be bad. While an excess of chemical will ensure ; (in most circumstances) that a safe road condition is achieved, it may also result in a ; substantial waste of chemical (with associated costs for this waste) and in ancillary ; damage to the road itself and to the surrounding environment. Ideally, one should apply ; what might be termed the “goldilocks” amount of chemical to the road: Not too much, ; and not too little, but just right.
