The Marshall method is a holistic approach to asphalt pavement mix design. Through a series of steps, it is able to establish the ideal asphalt content for a mix that will provide maximum strength and stability for its load. Through Marshall testing, engineers are able to: Select mineral aggregate and binder materials.

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.

Marshall stability and flow test values, density, and air voids in the mix and the mineral aggregate are all used for evaluation of trial mixtures of lab-mixed, lab-compacted (LMLC) asphalt mixtures. Marshall stability and flow tests can also monitor the production of the asphalt mixture using plant mix, laboratory-compacted (PMLC) samples.

Mix testing equipment includes the quartermaster sampler splitter and a variety of heavy duty lab mixers. A splitter divides the larger asphalt mix samples required in Superpave specifications. The hopper accepts samples up to 120lb of any mix with aggregate between 9.5 to 37.5mm. In addition, it quarters the samples into four equal parts.

This guide reviews the way asphalt mixture can be specified, with particular emphasis on the test methods used to measure performance.

BMD testing shows that the optimal asphalt content for cracking resistance may not always precisely match volumetric, recipe-based mix designs. This affirms the need for effective mixture performance tests like the IDEAL-CT, although there remains some resistance to this test because of its use of ambient temperatures, despite the IDEAL-CT's ...

Volumetrics in Asphalt Mixtures The question often arises about controlling asphalt mixtures during the mixture design process and during production. Many people who are reviewing these ... Instead, proper sampling and testing should be done to determine the cause of the variations and, if necessary to establish a new job-mix design. The ...

Mixture characterization tests are used to describe fundamental mixture parameters such as density and asphalt binder content. The three primary mixture characterization tests discussed here are: Bulk specific gravity. Theoretical maximum specific gravity. Asphalt content/gradation.

5.1 This test method may be used to generate information concerning the potential characteristics of handling, placing, compaction, and performance of an asphalt cold mix. 5.2 Workability is one of the main factors that influences the suitability and ultimately the performance of asphalt cold mix suitability for use as a roadway patching material.

Hot Mix Asphalt (HMA) mixer is used to mix aggregates and asphalt binder to prepare asphalt mixtures. The mixer spreads an even layer of binder on each aggregate. All laboratory mixture test on HMA requires this mixer in order to prepare the laboratory specimens for testing.
