Aggregate Production for Superpave HMA Purdue Aggregate Production for Superpave HMA by Ervin L Dukatz, Jr • Vulcan the characteristics that were determined by the Aggregate ETG to be important sand attributes needed to make stable HMA mixes What we have done in Texas is to note that the limestone manufactured sand particles are angular, cubical and thus meet the intent of the FAA
for hot mix asphalt (HMA) design have been devised, which first attempted to evaluate various properties of bituminous mixtures. Some of the more widely known of these design procedures are the Marshall, Hveem, Superpave, Texas and University of Nottingham methods (O'Flaherty et al., 2002). Marshall method

Production of Hot-Mix Asphalt with PMB Compactability . Aug 30, 2015In order to determine the production temperatures according to the Superpave and HSRV-E methodologies, the dynamic viscosity of the binder was measured using a rotating spindle apparatus at several temperatures, 130 to 190 C with 5 C interval, and at 3 to 5 different shear rate values for each temperature value.
Abstract. The validity of the Superpave fine aggregate angularity (FAA) requirement is questioned by both the owner agencies and the paving and aggregate industries. The FAA test is based on the assumption that more fractured faces will result in higher void content in the loosely compacted sample; however, this assumption is not always true.
CTR Programs. The Superpave Asphalt Technology Program is currently engaged in several important projects that extend its leadership position in Superpave research and implementation. Significant projects include research on Toner Modified Asphalt, the Effect of Crushed Aggregate Percent on Performance of HMA Mixtures, the Correlation of Field ...
Therefore, Superpave mix designs usually draw upon several different aggregate stockpiles and blend them together in a ratio that will produce an acceptable final blended gradation. It is quite common to find a Superpave mix design that uses 3 or 4 different aggregate stockpiles (Figure 1).
Superpave Mixtures 1. DESCRIPTION Construct a hot-mix asphalt (HMA) pavement layer composed of a compacted, Superpave (SP) mixture of aggregate and asphalt binder mixed hot in a mixing plant. Payment adjustments will apply to HMA placed under this specification unless the HMA is deemed exempt in accordance with Section 3077.4.9.4., "Exempt
Sensitivity of HMA Performance to Texas A&M University. Therefore, these properties need to be carefully measured and monitored in HMA production. In the current Superpave system, technicians determine coarse aggregate angularity by manually counting the number of fractured faces (ASTM D 5821) (American Society for Testing. More
