The Effect of Resins on Rheological and ageing Characteristics of Bitumen for Pavement
MATEC Web of Conferences, 2019 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 ...

Apparent Molecular Weight Distributions for Investigating Aging in Polymer-Modified Bitumen
Advances in Polymer Technology, 2021 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
Journal of Traffic and Transportation Engineering (English ed. Online), 2023 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
AIChE Journal, EarlyView.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).

Carbon Energy, EarlyView.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 ...
