Determining Reliability of an Asphalt Mix Design: Case of Marshall Method

Journal of Transportation Engineering, 2010
Asphalt mix design involves a number of tasks culminating in a laboratory estimation of suitable asphalt binder content which is recommended for bulk manufacture of the mix. Generally, the suitable binder content is that which on an average satisfy the specification limits.

Application of the Marshall Method to Hot Mix Design

1959
The primary purpose of this study was to determine the causes of extensive divergencies in test results obtained by different operators and different laboratories in the use of the Marshall test for hot mix design and to investigate discrepancies between laboratory-mixed and plant-mixed samples. The data and discussions presented are sufficient to draw

Prediction of Marshall Mix Design Parameters in Flexible Pavements Using Genetic Programming

Arabian Journal for Science and Engineering, 2020
The mix design of asphalt concrete is usually accomplished in the Iranian ministry of road and transportation according to the Marshall method. Marshall mix design parameters are a function of grading and properties of aggregates, amount and type of bitumen in asphalt mixtures.
