Rutting Analysis of 100 mm Diameter Polypropylene Modified Asphalt Specimens Using Gyratory and Marshall Compactors
(University Fed Sao Carlos, Dept Engenharia Materials, 2013)
Compaction technique used in Marshall design does not model the process of actual rolling procedures on site exactly. Carrying out laboratory compaction of dense bituminous mixtures with Superpave gyratory compactors is a ...
Rutting Prediction of Asphalt Mixtures Modified by Polypropylene Fibers via Repeated Creep Testing by Utilising Genetic Programming
(University Fed Sao Carlos, Dept Engenharia Materials, 2013)
A novel application of genetic programming (GP) for modelling and presenting closed form solutions to the rutting prediction for polypropylene (PP) modified asphalt mixtures is investigated. Various PP fibers have been ...
Optimal polypropylene fiber amount determination by using gyratory compaction, static creep and Marshall stability and flow analyses
(Elsevier Sci LTD, 2013)
Utilizing gyratory compaction technique for the preparation of asphalt specimens with 100 mm diameter moulds is an effective and realistic way of pavement laboratory testing. In fact, Marshall compaction is not a suitable ...
A new approach to neural trip distribution models: NETDIM
(Taylor & Francis LTD, 2009)
This paper develops and presents a new neural network approach to model trip distribution, which is one of the important phases of conventional four-step travel demand modelling. The trip distribution problem has been ...
Mechanical evaluation of asphalt-aggregate mixtures prepared with fly ash as a filler replacement
(Natl Research Council Canada-N R C Research Press, 2008)
The objective of this study is to investigate the effect of fly ash as a filler replacement on the mechanical properties of asphalt-aggregate mixtures. Utilization of fly ash, which is the by-product of coal-fired power ...
Number of design gyrations for 100 mm compacted asphalt mixtures modified with polypropylene
(Academic Publication Council, 2018)
There is no standard accepted by highway authorities on the compaction procedures of 100 mm diameter gyratory compactor specimens. In previous studies on gyratory compaction, the utilisation of either coring from 150 mm ...
Design Gyration Number Determination of 100mm-Diameter Asphalt Mixtures
(Springer International Publishing Ag, 2019)
At present, there is no accepted standard by highway authorities on the compaction procedures of 100mm-diameter gyratory compactor specimens. In previous studies on gyratory compaction, the method of either coring from ...
The effect of polypropylene fibers on asphalt performance
(Pergamon-Elsevier Science LTD, 2008)
Polypropylene fibers are extensively used in civil engineering applications for many years. These fibers are used in concrete as a three-dimensional secondary reinforcement. Due to adhesion between polypropylene fibers and ...
Modelling Marshall Design Test Results of Polypropylene Modified Asphalt by Genetic Programming Techniques
(Budapest University Technology Economics, 2015)
Determining Marshall design test results is time consuming. If the researchers can obtain stability and flow values by mechanical testing, rest of the calculations will just be mathematical manipulations. Marshall stability ...
Accumulated strain prediction of polypropylene modified marshall specimens in repeated creep test using artificial neural networks
(Pergamon-Elsevier Science LTD, 2009)
This study presents an application of artificial neural networks (ANN) for the prediction of repeated creep test results for polypropylene (PP) modified asphalt mixtures. Polypropylene fibers are used to modify the bituminous ...
