Accelerated Life Modeling of Superpave Mixtures
T&DI Congress 2014, 2014This study focused on reducing duration of the Hamburg wheel-tracking device (HWTD) test. Four fine-graded Superpave mixtures with 12.5-mm Nominal Maximum Aggregate Size (NMAS) were selected for this study. The average number of wheel passes to a 20-mm rut depth in the HWTD tests was used to build accelerated life models with a Weibull distribution ...

Modeling and Analysis of the Structure of Superpave Gyratory Compactor
Advanced Materials Research, 2009Superpave Gyratory Compactor (SGC) is used to design high quality mix asphalt specimen. In this research the structure of the SGC was analyzed, and the methods used in the Stewart mechanism are adopted. Based on the hypothesis that the parts made up of the mechanism are rigid body, no deformation exists in the connecting rods. Equations are deduced and

Investigation of the Gyration Angle of Superpave Gyratory Compactors
Journal of Materials in Civil Engineering, 2004The superior performing asphalt pavement (Superpave) hot mix asphalt (HMA) mix design system was a principal development of the Strategic Highway Research Program (SHRP). In the Superpave mix design system, the Superpave gyratory compactor (SGC) was developed as a laboratory HMA compactor, targeted at better simulating the field compaction of HMA mixes.

Superpave grading for high traffic volumetric criteria
2013 IEEE Business Engineering and Industrial Applications Colloquium (BEIAC), 2013The Superpave mix design system is a comprehensive method of designing paving mixes determined by the traffic, climate, and structural section of a particular pavement site. The first project of the Superpave mix design in Malaysia was in 1996. The application was in the technical specifications for runway and taxiway pavement for Kuala Lumpur ...

Applicability of Superpave to Modified Asphalts: A Mixture Study
Transportation Research Record: Journal of the Transportation Research Board, 1998Superpave binder and mixture specifications are currently being reviewed for their applicability to modified asphalts. This study was designed to evaluate a series of modified binders with the same Superpave performance grade (PG 76-22). The experiment was based on the following hypothesis: The performance characteristics for a given asphalt mixture ...
