Evaluation of waste toner asphalt containing crude palm oil from Congo: Rheological properties, compatibility, self-healing and aging characteristic

Case Studies in Construction Materials
This study investigates the impact of bio-based additives on waste toner-modified asphalt binder (WTMA) properties. Congo crude palm oil (CCPO) and waste banknote toner (WT) were chosen as modifiers.

The determination of the flexural creep stiffness of asphalt binder using bending beam rheometer

KSCE Journal of Civil Engineering, 1997
Rutting, fatigue cracking, and thermal cracking are the major types of distresses in asphalt pavement. These distresses are highly affected by the characteristics of asphalt binder (asphalt+additive). Binder properties play a key role in controlling low temperature cracking. The major objective of this paper is to determine the flexural creep stiffness

Ammonium Salts as Curing Agents to Obtain Ionic Epoxy Resins With a Thermoplastic‐to‐Thermoset Transition

Advanced Materials, Volume 38, Issue 51, 11 September 2026.
Ionic epoxy networks are prepared using ammonium salts as hardeners, leading to a two‐stage curing process with a thermoplastic‐like intermediate. This uncommon behavior enables extrusion and fabrication of thermoplastic prepregs that can be cured into thermoset composites.

Modeling of Tensile Creep and Recovery of Polymer Modified Asphalt Binders at Low Temperatures

Applied Rheology, 2015
The creep and recovery of asphalt modified with Elvaloy 4170 and polyphosphoric acid were studied at low temperatures, by inductive phenomenological methods. Two models of the tensile compliance function were investigated.

Investigation of Rheological Characteristics of Powdered Activated Carbon Modified Bitumen for Use in Self-Healing Mechanism of Asphalt Concrete [PDF]

Journal of Rehabilitation in Civil Engineering
Asphalt pavement is used in road construction with the aim of withstanding loads and heavy traffic. Increasing axial loads and heavy vehicle traffic lead to failures, including rutting, thermal cracking, and fatigue cracking.
