The increasing rate of traffic every day requires the roads to be made more stable. In order improve low and high temperature properties bituminous mixtures forming coating layer flexible pavements, binder in mixture is often modified with various polymers. most commonly used polymer modification styrene-butadiene-styrene (SBS). However, SBS, which very successful improving mechanical mixtures,...

Polymer-modified bitumen is used to combat different pavement distresses and to increase the life span of pavement. Unmodified bitumen cannot perform better with the range extreme minimum and maximum pavement temperatures. The polymers commonly used to modify the bitumen are ethylene vinyl acetate (EVA) styrene butadiene styrene (SBS). The aim this study to compare the performance of EVA modifi...

Abstract The durability, fatigue resistance, and low-temperature behavior of asphalt layers are greatly affected by the properties bitumen. Therefore, composition bitumen is frequently modified to improve performance mixtures. Sty-rene-butadiene-styrene (SBS) has been most often used additive recently. Researchers trying cohesive adhesive binders such polymer-based additives. In this study, 160...

Ten nitrate-selective electrodes based upon rubbery membranes containing various betaine salts as sensors covalently bound to a cross-linked polystyrene-block-polybutadiene-block-polystyrene (SBS) polymer have been produced. The membranes were robust, highly selective, and effective over a pH range of 2-8. The best nitrate-selective electrode fabricated contained 10% m/m dicumyl peroxide, 40% 2...

Thermoplastic elastomer/carbon nanotube composites are studied for sensor applications due to their excellent mechanical and electrical properties. Piezoresisitive properties of tri-block copolymer styrene-butadiene-styrene (SBS)/ carbon nanotubes (CNT) prepared by solution casting have been investigated. Young modulus of the SBS/CNT composites increases with the amount of CNT filler content pr...

Cohesion properties of the binder matrix within asphalt mixes and adhesion characteristics of the asphalt binder and aggregate particles are the two major mechanisms resisting against cracking in asphalt mixes. This study is focused on estimating crack resistance of asphalt mixes at intermediate temperatures through evaluation of cohesion and adhesion properties of binder-aggregate systems usin...

The durability of asphalt pavement is associated with the properties and performance binder. This work-study intended to understand impact blending Styrene-Butadiene-Styrene (SBS) conventional concrete mixtures calculating Optimum Asphalt Content (OAC) for mixture also; compare between SBS modified mixture. Two different kinds penetration grades, A.C. (40-50) (60-70), were improved 2.5 3.5% pol...

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...

Reusing reclaimed asphalt pavement material guarantees a substantial optimization of non-renewable resources, emissions reduction, and decreasing landfill space, along with the economic benefits associated saving costs purchasing transporting new aggregate binder for concrete mixture production. This study aims to investigate influence aged from on virgin binder’s rheological properties. Theref...

To obtain road bitumen with improved temperature and fatigue resistance, polymers and/or rubbers could be added to it. A particularly suitable polymer for modification is styrene-butadiene-styrene (SBS) copolymer but limited information available about the ageing behaviour of modified binders. In this work, two neat bitumens, different penetration grades, SBS-modified containing SBS amounts, we...
