Abstract
Buton Rock Asphalt, as a natural asphalt modifier, can be easily dissolved in matrix bitumen, which improves high temperature performance water stability performance and anti-aging performance of asphalt mixture greatly, and lead to the simple production process and easy promotion. However dry mixing process is taken into use in practice which means adding aggregates and BRA firstly, and then adding hot matrix bitumen and mineral power. Considering different adhesions of different parts in mixture to bitumen and characteristics of BRA, six kinds of new mixing sequences were tried and air void, high temperature performance, low temperature performance and water stability performance of mixture were compared to propose a kind of sequence which is easy and of which the mixture has better performance than the mixture of common process. In this sequence, aggregates and matrix bitumen are added first, and then BRA and mineral power are added.
