The two principle means of conserving fuel are identified as the stopping of fuel wastage, and the improvement of drying techniques to get more production from the fuel. Substantial savings can be made by eliminating cutbacks where possible. Emulsions or hot asphalt cement can be used satisfactorily in any application where cutbacks have been used except for prime coats on untreated bases. The use of cutbacks is primarily in the hands of the specifying agencies but a vigourous effort against this, plus the use of other asphalts where there is an alternate would save some 200 to 300 million gallons of potential fuel. Salvage operations are discussed which utilize used motor oil and other waste products. Methods are reviewed of improving the efficiency of drying (and so reducing the quantity of fuel used). A 1 percent reduction of the moisture content of the aggregate going into the dryer can save 10 percent of the fuel needed to heat and dry the aggregate. Reduction of the average volume of air used in heating and drying, reduction of the mixing temperature and the insulation of the bag collector housing will aid in fuel conservation.
