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 ...
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 ...
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 ...
Repeated Creep Behavior of Polypropylene Fiber-Reinforced Bituminous Mixtures
(Asce-Amer Soc Civil Engineers, 2009)
In recent years, research has been devoted to the control of permanent deformations in flexible pavements. In order to prevent rutting, fatigue, and low-temperature cracking, different types of polymer modifiers have been ...
Determination of the Optimal Polypropylene Fiber Addition to the Dense Bituminous Mixtures By the Aid of Mechanical and Optical Means
(Vilnius Gediminas Tech University, 2012)
Polypropylene fibers are completely native modifiers and they do not have any dependence on abroad in case of technology. When viewed from this point, the modification of bituminous binders with polypropylene fibers is a ...
A Recommended Neural Trip Distribution Model
(Hong Kong Universityersity Science &Technology, 2005)
In this study, it is aimed to develop an approach for the trip distribution element which is one of the important phases of four-step travel demand modelling. The trip distribution problem using back-propagation artificial ...
Prediction of Marshall test results for polypropylene modified dense bituminous mixtures using neural networks
(Pergamon-Elsevier Science LTD, 2010)
This study presents an application of neural networks (NN) for the prediction of Marshall test results for polypropylene (PP) modified asphalt mixtures. PP fibers are used to modify the bituminous binder in order to improve ...
