Nordic Road Administration Researches Residual Salt

Posted on October 3, 2013 by nradmin
The purpose is to develop a model for residual salt to be implemented. The model will be capable of calculating the residual salt in real time or predicting the development of residual salt on the road after spreading, by taking traffic, road and weather parameters into consideration. Defining the...
