The recycling of road and airport asphalt pavements requires greater reliability mix design in order to ensure proper rehabilitation effective reuse recycled concrete. Currently, internationally, the most procedures for concrete with RAP (Reclaimed Asphalt Pavement) refer guidelines developed by SuPerPave® Mixtures Expert Task Group. In this paper, according requirements European standard EN 13...

This doctoral thesis consists of a literature review, presented in two papers, and another six papers describing experimental studies of the influence of different kinds of wax and polyphosporic acid on bitumen and asphalt concrete mixture properties. The literature review should give an extensive description of the field of knowledge concerning wax in bitumen. Effects of wax in crude oil, bitu...

Abstract This research aims to assess the properties of Polymer Modified Bitumen (PMB) binder prepared with different types additives such as (Waste low density polyethylene (W-LDPE) and crumb rubbers (CR)and Styrene Butadiene (SBS)). Most these are sustainable materials since it is derived from old scrap materials. All above-mentioned (W-LDPE, CR SBS) were added percentages (2, 4, 6 percentage...

The bituminous pavement rehabilitation alternatives are mainly overlaying, recycling and reconstruction. In the recycling process the material from deteriorated pavement, known as reclaimed asphalt pavement (RAP), is partially or fully reused in fresh construction. Some of the advantages associated with pavement recycling are (i) less user delay (ii) conservation of energy (iii) preservation of...

Technology in transportation used available resources to make it safe, fast, suitable, easy, economic, and environmental transport people goods. Olive Husk became an problem as waste materials especially the Middle East where huge quantities are found. The objective of this research is investigate effect addition Ash (OHA) on properties asphalt concrete mixtures. Marshall Test was perform mixtu...

Bio-asphalt is a binder composed of bio-oil and petroleum asphalt under certain conditions. In this study, sludge (wt 10%) was added into matrix to prepare bio-asphalt for the first time. The effects on performance essence interaction between components were investigated using test, molecular dynamics (MD) simulation, density functional theory (DFT). Chemical analysis showed that ester compound...

Processing of the local Mubarek oil sludge with subsequent production a binder for foundation highways and roofing. Methods utilization were used to obtain binder. Innovative technology asphalt pavement by oxidation method has been developed. Investigations chemical composition roads elemental analysis dehydration its homogeneous state are presented.

To explore the applicability of steel slag porous asphalt mixture, interaction capability and microscopic interfacial mechanism between asphalt-binder aggregate-filler were investigated in this laboratory study. These objectives accomplished by comparing analyzing differences basalt aggregates interacting with asphalt-binder. The study methodology involved preparing mortar to evaluate penetrati...
