The special feature of such mixtures lies primarily in that they are made at a temperature of 95 ° C and a later start work at 70-90 ° C which reduces energy consumption during manufacture, between 40-50%, and a decrease in the emission of greenhouse gases in the same order. Further included in this article results of tests performed on formulations applying these new techniques, and comparing the data for the same formulation made according to the traditional way of hot mix.
