In the improved process from about 20 to about 80 percent tar sand is mixed with from about 80 to about 20 percent aggregate and from about 1 to less than about 5 percent liquid asphalt cement in a drum mixer to form an admixture, heating the admixture to a first elevated temperature (e.g., 250° and 400° F.) for a set period of time (e.g., 40 to about 90 seconds); and discharging the heated admixture at a second elevated temperature (e.g., from about 150° to about 350° F.) to produce asphaltic concrete. Preferably, the aggregate has a gradation of 10 to 25 percent passing a #4 sieve, and the admixture has substantially no added fines.
