What is the Marshall Test? The Marshall method of asphalt mix design is widely practiced in construction materials laboratories to select and proportion aggregate and asphalt materials for pavement construction.
Apr 27, 2017 · Marshal test is extensively used in routine test programs for the paving jobs. The stability of the mix is defined as a maximum load carried by a compacted specimen at a standard test temperature of 600 °C.
Jun 11, 2021 · The Marshall stability test is a part of the mix design procedure for bituminous pavements. Following are the objectives of performing the stability test: To anticipate the performance of a bituminous mix prepared using Marshall’s method of mix design. To determine the stability and flow values of hardened bituminous mix samples.
Test Procedure of Marshall Stability Test - Flow Test on Bitumen. The apparatus for the Marshall Stability test consists of the following: 1. Specimen mould assembly comprising mould cylinders 10.16cm diameter by 6.35cm height, base plate and extension collars. 2. Specimen extractor for extracting the compacted specimen from the mould.
SCOPE. 1.1 This method describes a procedure for the preparation of Marshall test specimens used in the design of bituminous mixtures, as well as specimens from field samples required for the determination of Marshall properties of dense and open-graded bituminous pavement mixtures. RELEVANT DOCUMENTS. 2.1 ASTM D6926-10. 2.2 Asphalt Institute MS-2.
11.6 PROCEDURE In the Marshall test method of mix design three compacted samples are prepared for each binder content. At least four binder contents are to be tested to get the optimum binder content. All the compacted specimens are subject to the following tests: • Bulk density determination. • Stability and flow test.
The basic Marshall test consists essentially of crushing a cylinder of bituminous material between two semi-circular test heads and recording the maximum load achieved (i.e. the stability) and the deflection at which the maximum load occurs (i.e. the flow).
