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...

Abstract At the end of their service life, asphalt pavements exhibit distresses such as cracking and ravelling due to aged bituminous binder. The recycling process reclaimed should compensate for deteriorated binder properties. main objective this study is compare two common strategies: use a softer rejuvenator. Three percentages, 0%, 40% 70% were evaluated. All blends prepared with similar pen...

This study aims to investigate the adhesion properties and moisture damage resistance between castor oil-based bio-asphalt (COBA) aggregates under action of thermal oxidation. Different dosages bio-oil (5%, 10%, 15%) were used prepare COBA by mixing it with petroleum asphalt. The short-term long-term aging simulated rolling thin-film oven test (RTFOT) over 85 min 385 min, respectively. boiling ...

The adhesion of mineral aggregates to asphalt binder is an essential point that attributes the quality and performance mixture. Moreover, considerable problem pavement could come from lack bonding between materials. Generally, depends on source or type aggregate binder. This study investigated adherence coverage palm oil mill sludge (POMS) modified with granite aggregate. Base penetration grade...

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...

Asphalt mastic, which consists of an asphalt binder and a mineral filler, provides critical adhesion viscoelasticity to mixture. The rheological response the mastic is mainly derived from its binder. In this study, simple laboratory test method proposed estimate relationship mastic. Two modified binders (3.5% 4.0% styrene–butadiene–styrene (SBS) by mass) were blended with limestone filler at si...

Warm-Mix-Asphalt (WMA) allows aggregates to be coated with asphalt binder at a temperature lower than the Hot-Mix-Asphalt (HMA) temperatures by using additives that make mixtures more workable and viscosity reduced. Due cost environmental advantages of WMA, it is now frequently employed in pavement. WMA two percentages zeolite (0.3% 0.5%) used this research. The optimum content has value compar...
