asphalt equipment superpave

In this blog post, we’ll discuss the impact of Superpave from the perspective of mix design, construction materials testing, and resources for laboratory equipment. Superpave Mix Design Superpave is an asphalt mix design method that has its roots in a report released back in 1984 by the Transportation Research Board (TRB) , America's Highways ...

Gilson’s asphalt testing equipment meets ASTM and AASHTO test standards for Marshall and Superpave mix design, binder, and pavement quality. Asphaltic concrete, or just asphalt, is the most widely used construction material for paving roadways. Demands on roadways from increased traffic volumes and axle loads are high and steadily increasing.

Mar 20, 2007 · THE SUPERPAVE CENTERS. Five Superpave Regional Centers will provide the technical leadership and assistance to ensure that the promise of more durable asphalt pavements becomes a reality. The centers will evaluate Superpave equipment and methodologies and work with highway agencies and industry to put them into practice.

What is Superpave mix?

Superpave limited was formed by Danny Gokool and Cecil Chin in May 2000. The main objective for forming Superpave limited was to service the small asphalt contractors in Trinidad and Tobago. The Superpave mix design method consists of 7 basic steps: Aggregate selection. Asphalt binder selection. Sample preparation (including compaction).

Under the Strategic Highway Research Program (SHRP), an initiative was undertaken to improve materials selection and mixture design by developing: 1. A new mix design method that accounts for traffic loading and environmental conditions. 2. A new method of asphalt binder evaluation. 3. New methods of mixture analysis.When SHRP was completed in 1993 it introduced these three developments and called them the Superior Performing Asphalt Pavement System (Superpave). Although the new methods of mi...

The Superpave Shear Tester (SST) (Figure 1) is used to characterize a HMAmixture’s resistance to permanent deformation (rut resistance). This characterization can be used as a performance test for HMA mixtures designed using Superpave mix design or other mix design procedures. The SST machine can perform several different tests to characterized HMA samples. The most common SST tests, the repeated shear at constant height (RSCH) and the frequency sweep at constant height (FSCH) tests subject a sh

SUPERPAVE Gyratory Compactor (SGC): Simulates the kneading action of rollers used to compact asphalt concrete pavements by applying a vertical load to an asphalt mixture while gyrating a mold tilted at a specified angle. SGC is the equipment most commonly used in volumetric mixture design.

blacktop or Superpave. Hot mix asphalt is composed of aggregate bound together into a solid mass by asphalt cement. The aggregates total ninety-three (93) to ninety-seven (97) percent by weight of the total mixture and are mixed with three (3) to seven (7) percent asphalt cement. It is manufactured in a central mixing plant where the asphalt ...

The need to understand the mechanical properties and relation between the material and the damage that occurs during the service life of road pavement (low temperature cracking, fatigue cracks and rutting deformations) was the motivation behind the development of a new classification system known as Superpave: Superpave is an acronym for Superior Performing Asphalt Pavements.

Superpave asphalt mix design (Superior Performing Asphalt Pavements), originally was accredited by the Transportation Research Board (TRB) back in 1984 and received additional governmental funding in 1991 through ISTEA. This methodology was meant to address the different and unique climate and traffic situations in various parts of the country.

Superpave Standards. All Greer Industries Asphalt operations are set up to meet Superpave mix designs. Our aggregate is also manufactured to Superpave specifications for size and structure so you can be assured that our asphalt will always meet the requirements of Federally funded highway construction.
