BRA is cheaper than ordinary asphalt, and the limestone mineral can replace part of the ore, with a very high cost perfor-mance. This paper, through the indoor experiment and test road engineering verification, proposes the mix proportion of material design and key construction technology of BRA modified asphalt pavement to improve the project performance of asphalt pavement, prolong the service life and reduce the life cycle cost.
