For instance, mix design for pavement in the Nevada desert with warm temperatures and light traffic would not fare well ...Apr 07, 2018 · Properties investigated were, Stability and Flow of Marshall, unit weight, voids in mineral aggregate, air voids, and voids filled with asphalt. The results indicated that optimum asphalt content (OAC) and characteristics of Marshall are significant variation different due to aggregate gradation and asphalt type. In the 1950s and 1960s, the Asphalt Institute was the de facto keeper of the Marshall standard and published it in "MS-2, A Manual of Mix Design Methods for Asphalt Concrete." Although ASTM was the main home of the Marshall method (D-1889), the method was a reflection of MS-2.The original Marshall method is applicable only to hot mix asphalt paving mixtures containing aggregates with maximum sizes of 25 mm or less. A modified Marshall method has been developed for aggregates with maximum sizes up to 38 mm. Procedures for 6-inch diameter specimen are given by ASTM D5581.optimum asphalt content , and the evaluation of hot asphalt mixture properties by using Asphalt institute specification(1997). Objectives of the study The objectives of this study are the following : 1- Determination of the optimum asphalt content for seven specimens of hot asphalt mixture by using Marshall mix design method.ANN for the prediction of the volumetric properties of the asphalt mix [28]. In 2017, Ivica and Ivan proposed an ANN for the prediction of the air voids and the asphalt content of asphalt mixes in Croatia [29]. In 2018, Baldo et al. used the ANN technique for the prediction of the mechanical properties of asphalt mixes (stability and ow) [9].The properties of asphalt mix and Marshall Criteria Flakiness, % 15.8 15.3 n/a Property Result Marshall Criteria Abrasion loss, % 20.8 n/a Design Asphalt Content, % 5.5 4.5-6.5 Sand equivalent, % n/a 92 n/a Stability, Kg 1652 1000 min.

The asphalt cement use varies from 4.5% to 6.5% and having penetration grades of 80/100. The mix were compare in term of Marshall Properties such as stability and flow; and volumetric properties are mixture density, Voids Filled with Asphalt (VFA), Voids in Mineral Aggregate (VMA), and Voids in Total Mix (VTM).A total of 180 asphalt concrete samples of 4 in diameter were prepared in the laboratory with different dosages of CR and SCBA. The Marshall stability, Marshall flow and indirect tensile properties of the specimens were investigated in the laboratory. orlando drop tower wiki -fc
