The effect of sulfur and asphalt contents in SAS mixtures on Marshall Stability is shown in Figure 3 [15]. The stability values tend to increase with sulfur content but decrease with asphalt addition. It is interesting to note that without the sulfur and asphalt, sand mixes would have little or no stability. The data also indicate a wide variety of mix designs are possible whose stabilities are consistant with Asphalt Institute suggested values for conventional asphaltic mixes. 

The properties are consistent with those suggested by the Asphalt Institute [48] for light, medium and heavy traffic categories, except in the area of air void content, which can be adjusted through changes in aggregate grading and binder content. At S/A...

The U.S. Bureau of Mines participated in a field trial of sulfur-asphalt concrete pavement on U.S. Highway 93 near Boulder City, Nev. in January 1977. This test section is 2100 ft long. The aggregate-asphalt-sulfur (AAS) system was used to mix the ingredients. The sulfur and AC 40 asphalt cement were introduced into the pugmill as individual components. The sulfur comprised 27 w/o of the total binder. The aggregate used in the mixture was a crushed volcanic rock which conformed to the Asphalt Institute type IVb gradation. This test section is now in post-construction evaluation.

A more detailed listing of these ASTM methods is given at the end of this paper. The criteria suggested by the Asphalt Institute (5) and Shell (I, 2) for asphaltic concrete (A/C) under heavy, moderate, and light traffic conditions were used to evaluate these test results. Table III lists recommended test values (5) for conventional A/C mixes deemed necessary to withstand light, medium, or heavy traffic.

Equations 1.2 and 1.3 are proposed to be used by the Asphalt Institute of the United States (Asphalt Institute MS-1). They are applicable to materials classified as A-7, A-6, A-5, A-4 and finer A-2 soils (AASHTO designation) or CL, CH, ML, SC and SP (USCS), or in general for materials that are estimated to have a resilient modulus of 207 MPa or less. 

Bitumen (or asphalt), apart from being used in the production of bituminous mixtures for road construction, also has a wide range of applications, such as waterproofing, protective coatings and a range of industrial products (more than 250 Asphalt Institute MS-4 1989).
