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 ...

Preliminary evaluation of the materials in Egypt for Superpave implementation

Road Materials and Pavement Design, 2012
The Egyptian code of practice for the design of asphalt mixtures is based on Marshall mix design methodology. There is a significant shift to Superpave mix design worldwide and Egypt is one of the countries that is expected to follow this shift. For the transition to be smooth and easy for practitioners, an analysis was done to evaluate the compliance ...

SUPERPAVE: PROS AND CONS, OR HOW SUPERPAVE IS USEFUL TO US

Avtoshliakhovyk Ukrayiny, 2022
The main positions of the Superpave system regarding the principles and methods of predicting the durability of asphalt concrete in various environmental and transport conditions of their operating are considered. Arguments in favor or unacceptability of bitumen and asphalt concrete quality indicators provided by the system are presented. This concern:

Superpave and the Aggregate Industry

Journal of ASTM International, 2006
Abstract The Superior Performing Asphalt Pavement (Superpave) mix design system was developed under the Strategic Highway Research Program, which was completed in 1993. Superpave consists of new methodologies for evaluation and selection of hot mix asphalt (HMA) material constituents along with new laboratory compaction protocols. During

Coarse Superpave Mixture Sensitivity

Transportation Research Record: Journal of the Transportation Research Board, 2000
Asphalt-aggregate mixture sensitivity has long been recognized for its potential negative impact on performance if variables including the asphalt content (AC) and the percent that passes the 0.075-mm sieve (p0.075) are not carefully controlled during construction.

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.

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 ...

Fatigue Characteristics of Superpave and Hveem Mixtures

Journal of Transportation Engineering, 2005
A study was conducted to evaluate the fatigue characteristics of hot mix asphalt (HMA) mixtures designed using the Superpave volumetric method and Nevada's Hveem method. Fatigue characteristics were evaluated using the flexural beam fatigue test under the strain-controlled mode of loading.

Oregon's Superpave Implementation

1997
Oregon Department of Transportation (ODOT) has specified performance-based asphalts (PBAs) since 1991. Developed by the Pacific Coast Conference on Asphalt Specifications (PCCAS) in 1990, the PBA concept uses conventional test methods for classification and facilitates binder selection based on climatic conditions.

Colorado Begins Superpave Validation

1997
One of the first applications of Superpave technology in Colorado was at a high traffic intersection near Denver in 1994. The project was developed to demonstrate whether Superpave asphalt technology could solve a recurring problem of rutting in a very severe traffic environment.
