Performance evaluation of Marshall and Superpave asphalt mix design methods: a volumetrics-analysis based approach

Australian Journal of Civil Engineering
This comparative study presents a detailed experimental investigation to analyse two significant asphalt mix design methods i.e. Marshall and Superpave on the basis of optimum bitumen content (OBC), volumetric properties incorporating air voids, voids in

Characterization of particle movement in Superpave gyratory compactor at meso-scale using SmartRock sensors

Construction and Building Materials, 2018
Compaction is one of the most critical steps in asphalt pavement construction that ultimately impacts pavement performance. In the laboratory, the Superpave gyratory compaction (SGC) method is widely accepted because it applies both shear and compression

Municipal Implementation of Superpave Technology

Transportation Research Record: Journal of the Transportation Research Board, 1999
The reconstruction of 30 km of County Road 2 by the county of Frontenac in 1996 provided the opportunity for municipal implementation of Superpave performance graded asphalt binder and volumetric mix design technology. The Superpave surface course asphalt mix was placed over a cold in-place recycled binder course pavement.

Acceleration of Superpave Mix Design: Solving Multi-Objective Optimization Problems Using Machine Learning and the Non-Dominated Sorting Genetic Algorithm-II

Transportation Research Record
The traditional asphalt mix design requires the preparation of many samples to test, which consumes much time and labor. Moreover, selecting aggregate gradation and asphalt content based on individual experience until a mixture’s properties meet a ...

Performance of Superpave Projects in Louisiana

Transportation Research Record: Journal of the Transportation Research Board, 2011
The Louisiana Department of Transportation and Development (Louisiana DOTD) initiated the implementation of the Superpave ® system by the end of the past decade. This study evaluated 8 to 10 years of field performance of 21 Louisiana Superpave projects, which included five Interstates, four U.

Optimization of Superpave Mixture Volumetric Properties

International Journal of Pavement Engineering, 2002
The Kansas Department of Transportation (KDOT) currently monitors up to 19 parameters for the Superpave mixtures under its Quality Control/Quality Assurance (QC/QA) program. Data from six Superpave projects of KDOT was analyzed in this study to find the optimum combination of volumetric parameters, air voids and Voids in Mineral Aggregates (VMA), for ...

Evaluation Of Superpave In Kentucky

1999
Approximately 93 percent of all pavements in the United States are surfaced with hot-mix asphalt (HMA). For many decades, most asphalt pavements were designed using the Marshall mix design method. In 1987, the Strategic Highway Research Program was established with 50 million dollars being allocated for asphalt pavement research.

Flat and Elongated Aggregates in Superpave Regime

Journal of Materials in Civil Engineering, 2000
Some states have recommended changing the definition of flat and elongated aggregates from 5:1 to 3:1 and an increase in the maximum allowable percentage of flat and elongated (F&E) particles to 20% or higher in the Superpave aggregate specification. Engineering justification and performance data are required to rationally establish the criteria for ...
