The Effect of Resins on Rheological and ageing Characteristics of Bitumen for Pavement
Bitumen consists of thousands of hydrocarbon molecule types with each molecule contributes to the overall bitumen characteristics. Therefore, it is important to identify the influence of each chemical component of bitumen that altogether constructs the ...

Investigation of the Temperature Performance of Bitumen Modified with Egg Shell Waste
This study was conducted to improve the heat performance of bitumen. The effect of eggshells on the performance of bitumen was investigated. Eggshell waste was ground and mixed with bitumen at 1%, 2%, and 3% by weight.

Apparent Molecular Weight Distributions for Investigating Aging in Polymer-Modified Bitumen
The oxidative aging of bituminous binders affects the performance and durability of pavements. In the case of polymer-modified binders, aging involves both bitumen and polymers and has a strong impact on the whole architecture of the material.

Investigation of internal phases of linear SBS modified bitumen at the nanoscale using AFM PF-QNM
Currently, few studies explore the internal phases of styrene-butadiene-styrene (SBS) modified bitumen at the nanoscale, though the surface phases of SBS modified bitumen have been deeply understood through a lot of research.

Synthesis of functionalized polyolefins in a new continuous bench‐scale reactor apparatus
Abstract In‐reactor functionalized polyolefins (FPOs), produced by molecular catalysts, are a new class of polymer materials with applications ranging from high performance adhesives to bitumen compatibilization. In this work, we disclose a procedure for the synthesis of FPOs in a new Continuous Bench‐scale Reactor Apparatus (COBRA).

This study employs a simple solid‐phase alkali‐oxygen oxidation (SAO) method to extract inherent components (humic acids) from coal. We successfully extracted yellow, brown, and black humic acids by adjusting the amount of alkali. Among them, brown humic acid extraction created abundant ultra‐micropores and closed pores, greatly enhancing sodium ...

Separation and Recovery of Bitumen from Oil Sand by CO2 Desorption of Amine Solution
Bitumen extracted from oil sand has garnered increasing attention as an alternative energy source for fossil resources. Since oil sand consist of a mixture of bitumen (10-15 wt. %), water (4 wt. %), and sand (80 wt.
