the performance of asphaltic pavements during their service life is highly dependent on the mechanical properties of the asphaltic layers. therefore, in order to extend their service life, scientists and engineers are constantly trying to improve the mechanical properties of the asphaltic mixtures. one common method of improving the performance of asphaltic mixtures is using different types of ...

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...

Flexible pavement is the preferred type in construction of roads and highways. A huge amount non-renewable materials industrial products like Olive Husk Ash (OHA), aggregates, bitumen, cement, lime, other additives are used during maintenance system. Needless to say, extraction production these unmaintainable. Moreover, wastage materials, worsening environmental conditions, insufficient resourc...

This study investigated the impact of using modified bitumen binders and additives to enhance physical characteristics asphalt mixtures at high, medium, low temperatures. Both basic rheological bituminous were tested by adding Styrene-Butadiene-Styrene, a type thermoplastic elastomer, as chemical additive various fractions (3.5%, 4%, 4.5%), two kinds Bitumen: Kraton styrene block copolymers Eur...

The use of reclaimed asphalt pavement (RA) in new asphalt pavements can provide important economical savings, while reducing the negative environmental impact. The European research project PARAMIX aims to improve the techniques for hot mix recycling in plant and cold mix in situ recycling, so as to increase the amount of reclaimed asphalt and develop competitive road pavement rehabilitation te...

Conductive asphalt concrete with high thermal conductivity has been proposed to improve the solar energy collection and snow melting efficiencies of asphalt solar collector (ASC). This paper aims to provide some insight into choosing the basic materials for preparation of conductive asphalt concrete, as well as determining the evolution of thermal characteristics affected by environmental facto...
