    and "Simple Performance Testers for Superpave Mix Design". It is necessary to note that a recent study conducted at the National Center for Asphalt Technology (NCAT), "Performance Tests for Hot Mix Asphalt", was initiated to compare available tests and select the best test .   Four of the eight mixtures will be placed at two thicknesses. The research will be used to validate proposed changes to the Superpave binder specification and will provide additional validation data for assessment of the proposed simple performance test and Pavement Design .

      The repeated-load test is performed with the asphalt mixture performance tester (AMPT). The algorithm currently used in the AMPT to determine flow number was found to be extremely sensitive to noise in the data and identifies erroneous flow number results, especially for modified mixes. Simple Performance Tester for Superpave Mix Design. • Phase IV in progress to procure four additional SPTs according to revised specification and develop ruggedness test plan • One new SPT capable of measuring dynamic modulus master curve for pavement structural design Advanced Asphalt Technologies, LLC.

      Flow tests (flow number and flow time) are explicatory indices for the evaluation of the rutting potential of asphalt mixtures. This study investigates the rutting susceptibility of various asphalt mixtures subjected to static and dynamic creep tests. Four wearing course gradations were selected; and asphalt mixture’s specimens were fabricated using Superpave gyratory compactor.

TRB’s National Cooperative Highway Research Program (NCHRP) Report -- Simple Performance Tester for Superpave Mix Design: First-Article Development and Evaluation presents the findings of a research project to develop a practical, economical simple performance tester for use in routine Superpave mix design and possibly in the characterization of hot-mix asphalt materials for pavement structural design.

sonnel responsible for design and production of hot mix asphalt. The Superpave volumetric mix design procedure (AASHTO MP2 and PP28) developed in the Asphalt Research Program (–) of the Strategic Highway Research Program (SHRP) does not include a simple, mechanical “proof” test analo.

Superpave Level-I mix design, however, entirely depends on the volumetric properties of the mixture, without evaluating the potential performance of mixtures.

In order to cope with the increasing demand for a simple performance test, extensive research has been conducted recently across the U.S. and new test methods and/or testing equipment.

The simple performance test will be used in conjunction with the Superpave volumetric mixture design. This test is intended to add an additional level of reliability to assure design mixes are able to resist the applied trafficking with minimal permanent deformation (rutting).

The objectives of this research were to (1) design, procure, and evaluate simple performance testers for use in Superpave mix design and in HMA materials characterization for pavement structural design and (2) evaluate and refine the indirect tensile test (IDT) procedures proposed for use as the simple performance test for low-temperature cracking and as the materials characterization test.

SIMPLE PERFORMANCE TEST FOR SUPERPAVE MIX DESIGN. This report presents the findings of a research task to identify a simple test for confirming key performance characteristics of Superpave volumetric mix designs. In this initial phase of the work, candidate tests for permanent deformation, fatigue cracking, and low-temperature cracking were.

Quality control and quality assurance (QC/QA) specifications typically define the asphalt mixtures by how close the as-built mixture meets the requirements of the as-designed mix. A common QC/QA specification for asphalt pavement construction is based on controlling the volumetric properties of compacted asphalt mixtures such as air voids, asphalt content, and aggregate gradation.

A Practical Look at the Simple Performance Tests: Louisiana's Experience (With Discussion) The Superpave volumetric mix design procedure developed during the Asphalt Research Program of the Strategic Highway Research Program did not include a mechanical “proof” test similar to the ones commonly used in the Marshall mix design or Hveem mix design such as the Marshall stability and.

state. The original intention of Superpave had been to test trial mix designs with performance tests in a similar way to the Marshall and Hveem methods. Devices such as the Simple Shear Tester (SST) and Simple Performance Tester (SPT, now AMPT) were attempts at the performance tests.The current method of determining the moisture susceptibility of asphalt concrete mixtures is American Association of State Highway and Transportation Officials (AASHTO) T AASHTO T is based on the Marshall mix design method, however the current state of the practice for an asphalt concrete mixture design is the Superpave mix design method.
