Given the specifications for an asphaltic concrete mixture and the results of a sieve analysis, determine the proportion of different aggregates to obtain the required gradation. Coarse aggregates: 60% Fine aggregates: 35% Filler: 5%
A sample of aggregate weighing of 3800g. 45.5% retaining on sieve No.4. and 48.5% it is retaining on sieve No 200. If bulk specific - gravities of coarse , fine and mineral filler aggregates are 2.59 , 2.66 , and 2.69 respectively, determine the optimum asphalt conten as a percentage of the total mix if results obtained using the Marshall method are shown in the table below. The specific gravity of the asphalt is 1.05. Given that the specifications required minimum Marshal Stability of ( 7kN ). Flow (2-4mm) and percent of air voids (3-5%).

The Superpave volumetric procedure has been widely implemented, with success- ful results. However, the method lacks a strength test to verify the suitability of the Superpave mixes. Research completed in NCHRP Project 9-19 developed "simple performance tests" for asphalt concrete (Witczak et al., 2002), currently called the Asphalt Mixture Performance Tester, AMPT, Figure 9.34. The AMPT is not currently a requirement for Superpave mix design, but implementation studies are underway. In addition, the test method was designed to capture the material properties needed for the Mechanistic Empirical Pavement Design System, MEPDS. The equipment and associated protocols of the AMPT tests are designed to cap- ture the viscoelastic behavior of asphalt concrete. Tests based on measurement of dynamic modulus (for both of permanent deformation and fatigue cracking), flow time (permanent deformation), and flow number (permanent deformation) were selected for further field validation. The three…
