Marshall Stability and Flow Test is basically one portion of the process beside Void ratios and Density calculations as other processes. Marshall Stability Test gives an idea about the sustainability and strength of the asphalt mix of various proportions under the dynamic loading of the traffic.As per the standard procedure for the Marshall Stability test, the sample is first prepared having specific amount of aggregate of specific gradation along with some suitable amount of bitumen or binder content as stated. Marshall Stability and flow values along with density, air voids in the total mix, voids in mineral aggregates or voids filled with asphalt or both filled with asphalt are used for laboratory mix design and evaluation of asphalt mixtures. In addition, Marshall Stability and flow can be used to monitor the plant process of producing asphalt mixtures.
Marshall Stability and flow may also be used to relatively evaluate different mixes and the effect of conditioning such as with water.Marshall Stability Apparatus. The Marshall Stability and flow test results are applicable to dense-graded asphalt mixtures with maximum size aggregate upto 1 in. For the purpose of mix design, Marshall Stability and flow test results should consist of the average of a minimum of three specimens at each increment of binder content range is generally selected on the basis of experience and historical testing data of the component materials, but may involve trial and error to include the desirable range of mix properties.
- Sample in accordance to ASTM C117 (ASTM 2004) using the plain water washing method. Once OBC is obtained, Marshall specimen of different thickness was fabricated. The thickness selected was 35, 50 and 65 mm, at an allowable limit of ±1 mm. Initially, the specimen was prepared using 1200 g of aggregates, compacted at both.
