In this paper, we use big gap drainage asphalt mixture to improve asphalt pavement per-formance. To ensure the distribution of test, the optimum dose of asphalt and the dose of admix-ture, we make a indoor test. Meanwhile, we verified that this mixture has excellent drainage per-formance, which will play a guiding role in the practical application of the big gap drainage as-phalt mixture.
