摘要：

Aggregate of natural crush stone in hot mix asphalt is applied to gap gradation mixed with the AC-20 binder, in accordance with Marshall mix design. Laboratory tests were conducted, and the single-factor variance analysis (ANOVA) is employed to estimate the significance of the gradation mixture properties. Based on permanent deformation tests and analytical results, sieve of 2.36 mm may be omitted for nominal maximum aggregate size (NMAS) of 12.5 mm, and sieve of 4.75 mm may be omitted for NMAS of 19 mm, in the case of the shortage of aggregate.
