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. Browse by Category. 9. In the Superpave method, this step can be broken up into 4 substeps: Prepare several initial samples, usually two at the proposed design asphalt content, two at 0.5 percent below the design asphalt content and two at 0.5 percent above the design asphalt content. 1.1 This method is used to design Asphaltic Concrete mixes using 4-inch diameter Marshall apparatus. This is because the Asphalt Institute design method requires complex calculations of the horizontal strains induced in the pavement system under load. 3.4. The reason could be that the Asphalt institute method gave conservative design based on empirical equations. Shop › Product Catalog. The average monthly temperature data for the three locations is given in Table 2 [5]. 20 – 25% Cracking 2. a ), and the effective binder content(P. be In this mix design method, asphalt binder content is selected at 4.0 percent air voids as in the traditional Superpave mix design system, then in production, the asphalt binder content is increased to an amount that will correspond to a “regressed” 3.5 percent air voids.
