The double barrel (DB) is the essential functional part of continuous asphalt mixing equipment, which affects the mixing uniformity of asphalt mixture. To improve the mixing uniformity of the mixture, a double barrel with differential velocity (DBDV) was proposed. The structure of DBDV and its influence on the mixing uniformity of the mixture were described. The current double barrel is divided into single horizontal shaft DB and double horizontal shaft DBDV. The discrete element simulation is used to compare the mixing uniformity of two kinds of DB. The results show that the mixing uniformity of double horizontal shaft DBDV is better than that of the single horizontal shaft DB, proving the correctness and rationality of the above analysis.
