“…These results are in accordance with those of several authors such as Gorkem and Sengoz [2], Attaelmanan et al [3] and Sangita et al [4]. These authors found that the modification of the bituminous mconcretes by different modifiers improved resistance to indirect tensile ITS.…”

Abstract. The aim of this work is to contribute to the improvement of the mechanical properties of bituminous concrete by modification of bituminous concrete. In this study, we present the results of the indirect tensile strength "ITS" of modified bituminous concrete by the combination of two modifiers, one is a plastomer EVA (Ethylene Vinyl Acetate) and the other is a industrial waste from the shoe soles grinding NBR (Nitrile Butadiene Rubber) as crumb rubber. To modify the bitumen a wet process was used. The results show that the modification of bitumen by EVA-NBR combination increases their resistance to the indirect traction "ITS" compared to the bituminous concrete control. The mixture of 5% [50% EVA+ 50% NBR] is given the best result among the other associations.

“…The modification can be effected in two ways [1], the first being the modification of bitumen (wet method) [2][3], and the second consists in the direct addition of the modifier during the mixing operation of the bituminous concrete (dry process) [4].…”

“…Besides, below a certain threshold, said "temperature of cessation", any also remarkable effort in terms of energy transferred with the roller does not improve appreciably the density of the layer, but it is useful only for making more attractive the surface appearance (Attaelmanan et al 2011;Sanchez-Alonso et al 2011). Of course, this study has especially deepened the role of the temperature, the characteristics of the roll, its speed and the number of passes, assuming constant other important variables (such as gradation, bitumen content, aggregate shape, bitumen/filler ratio) that can influence the compaction.…”

Compaction of Open-Graded HMAs Evaluated by a Fuzzy Clustering Technique

et al. 2015

The aim of this paper is the proposal of an expeditious procedure to be used during the execution of an asphalt layer for improving the compaction task. This procedure, based on a fuzzy clustering technique, starts from the knowledge of some information recorded by ordinary measuring instruments and provides an aid to the decision-maker on the number of roller passes needed to achieve a specific density at a certain temperature. This result can be deduced with great rapidity during the paving operations on site without waiting for the time spent in the core extraction and in the subsequent laboratory analysis. In this way it is possible to identify more precisely which aspects of the execution have to be corrected for performing the best compaction.

“…Hinishoglu and Agar (2004) reported the use of high density polyethylene waste as bitumen modifier and they concluded that the mixtures containing this material provide better resistance against permanent deformations. The viability of using high density polyethylene as a modifier for asphalt paving bitumen was also investigated by Attaelmanan et al (2011) showing that the performance of the modified asphalt mixtures is better than the conventional ones with a reduced moisture and temperature susceptibility. Analogous results are reported by Zoorob and Suparma (2000).…”

A Comparative Study of Bituminous Mixtures with Recycled Polyethylene Added by Dry and Wet Processes

2015

The use of "silo bags" is a common technique developed in Argentina for the low cost on farm storage of grains and nowadays, they are extensively used in different countries all around the world. They are big plastic bags made of three layers of polyethylene where different types of dry grains can be stored in a hermetic ambient. After several uses the silo bags are damaged and must be replaced. These materials are hardly biodegradable and they occupy an important volume in landfills. This paper presents a comparative laboratory study about the influence of different percentages of recycled polyethylene from silo bags added by dry and wet processes on a bituminous mixture compared to two other mixtures containing conventional bitumen and polymer modified bitumen. The obtained results are presented and discussed showing that the reuse of recycled polyethylene from silo bags in bituminous mixtures is an environmental friendly alternative.
