Application of Cantabrian and Binder Drainage Tests in Designing of Porous Asphalt Binder Content [PDF]

open access: yes, 2004
Traditional mix design methods which normally incorporate the Marshall test are not appropriate to design porous asphalt because of the insensitivity of the Marshall stability values to variations in binder content.

The impacts of neighbourhood traffic management [PDF]

open access: yes, 2012
A major traffic-related problem faced by residents is speeding, which not only causes safety concerns, but also noise issues. Traffic calming is a much favoured traffic management tool employed by road controlling authorities to primarily reduce ...

The Effect of Demineralization on Coal Functional Group Pyrolysis: Rank‐Dependent Dual Mechanisms of Structural Reorganization and Mineral Catalysis

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Coal pyrolysis, as a key thermochemical conversion process, is significantly influenced by inherent minerals, yet their role across different coal ranks remains inadequately understood. This study investigates the effect of acid‐washing (demineralization) on the thermal decomposition of six functional groups (aliphatic C–H, aromatic C–H/C=C, C=

Advanced Investigation of the Elimination of Methylene Blue From Wastewater Using Activated Carbon–Copper Oxide Nanowires: New Perspectives With Statistical Physical Modeling

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT In this study, the actual route of methylene blue (MB) dye adsorption by using fabricated polyfunctional activated carbon–copper oxide nanowires (AC@CuO‐NWs) from bulky wastewater bodies has been investigated. To better understand the exact pathway of the adsorption process, a prominent statistical physics formalism or grand canonical ...

Carbon‐Supported Dual‐Nickel Atom Catalysts With Stabilized Ni─N3 Active Sites for Efficient CO2 Electroreduction

open access: yesCarbon Energy, EarlyView.
Dual‐nickel atom catalysts (Ni‐DACs) are developed to stabilize unsaturated Ni─N3 atomic sites by constructing N3Ni─NiN3 dual‐atom structures from coal. Benefiting from the modulated electronic structure that optimizes intermediate adsorption, Ni‐DACs outperform Ni‐SACs in CO2 electroreduction, achieving a max FECO of 98.6% at −0.8 V vs RHE and a TOF ...

The modification of bituminous materials using tall oil pitch : a thesis presented in partial fulfilment of the requirements for the degree of Master of Technology in Chemical Technology at Massey University, New Zealand [PDF]

open access: yes, 2003
There are economic, occupational safety and health, and environmental advantages in using tall oil pitch (TOP) as a bitumen extender. However, before bitumen modified with TOP can be used commercially in New Zealand, it must meet the requirements of the ...

Supercritical water deasphalting and desulphurization of heavy fuel oil with comprehensive molecular‐level analysis and techno‐economic analysis

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Supercritical water deasphalting. Abstract The removal of sulphur from heavy fuel oil (HFO) is essential to address environmental concerns and comply with the stringent regulations imposed by the International Maritime Organization (IMO) in 2020. Previously, the acceptable limit for sulphur was 3.5 wt.%, but it was recently changed to 0.5 wt.%.
