Preparation and Performance of SBR/SiO2‐Modified Emulsified Asphalt Mixtures Incorporating Recycled Aggregates

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
To address the technical bottlenecks associated with the poor overall performance of emulsified asphalt mixtures incorporating high‐proportion (84 wt%) recycled asphalt pavement (RAP) aggregates, this study proposes a synergistic modification strategy using styrene‐butadiene rubber (SBR) and nano‐silica (SiO2), coupled with the regulation of cement and

Evaluation of the Durability of a Waste Plastic–Enhanced Asphalt Road Pavement in Extreme Future London Weather Conditions

Advances in Materials Science and Engineering, Volume 2026, Issue 1, 2026.
Climate change is increasing the frequency and intensity of extreme weather events, posing challenges to the durability of asphalt road pavement systems. Incorporating waste plastics, such as polyethylene terephthalate (PET), into asphalt mixtures has been proposed as a potential approach to reduce bitumen demand and modify mechanical performance ...

DETERMINING THE RHEOLOGICAL PROPERTIES OF ASPHALT BINDER USING DYNAMIC SHEAR RHEOMETER (DSR) FOR SELECTED PAVEMENT STRETCHES

International Journal of Research in Engineering and Technology, 2013
This paper aims to study the rheological properties of the binder taken from four years old flexible p avement stretch. The stretch was divided into six different sections based on the th ickness of the surface course. Originally, 60/70 gr ade asphalt binder was used throughout the pavement stretch.
