    <subfield code="a">&lt;p&gt;Hot Asphalt Mixtures (HMA) is composite of mineral aggregates, asphalt binder, and air voids. Mineral aggregate is covered about 95 percent of the total mixture. In asphalt pavement production, aggregate gradation is specified in a large percent passing range to use locally available material and to be economical. This large gap of the aggregate gradation specification range alters the performance of the asphalt concrete by change the aggregate surface area. The aggregate surface area has a critical role in the hot mix asphalt performance by altering the coated asphalt film thickness on the aggregate surface and this controls overall mixture properties. Various studies have shown that the variation aggregate surface area has a significant effect on the performance of asphalt concrete pavements by using Marshall Test methods. This study was mainly evaluated the effect of aggregate surface area on the mixture volumetric properties and moisture damage. Different aggregate surface areas were determined in the blending aggregate gradation percent passing specification range by multiplying empirical surface area factor. Using 3.12m2/kg, 4.58m2/kg, 6.19m2/kg, 7.93m2/kg, and 9.64m2/kg aggregate surface areas a number of trial mixes have been prepared using the Marshal Mix design method. The stability, flow, volumetric properties, and moisture resistance of the hot mix asphalt were discussed.&lt;/p&gt;</subfield>
