Review of Lab-Accelerated Aging Techniques of Asphalt Mixes

open access: yesJournal of Engineering
Bitumen aging contributes to main pavement distress due to the changes in rheological, chemical, and physical characteristics of bitumen. Mainly, aging process can be divided into two categories, the first category namely short-term aging takes place ...

Analysis of possible use of pyrolytic products as binders in asphalt mixes

open access: yesGrađevinar, 2016
New binders are produced in order to reduce dependence on crude oil. This study aims to evaluate pyrolytic products and their blends with bitumen, as a possible substitution for bitumen.

Impacts of coal smoke on infant mortality: Evidence from industrializing Japan

open access: yesThe Economic History Review, EarlyView.
Abstract This study investigates the health consequences of coal smoke during Japan's early industrialization. Using fixed‐effects models and a prefecture‐level panel dataset on actual coal consumption and infant mortality from 1899 to 1910, this study finds that higher coal consumption was positively associated with infant mortality.

Optimal Hedging Strategies in the Low‐Sulphur Bunker Fuel Landscape

open access: yesEuropean Financial Management, EarlyView.
ABSTRACT The IMO2020 regulation for the green transition in shipping turned the industry into using two compliant bunker fuels: very low‐sulphur fuel oil (VLSFO) and low‐sulphur marine gas oil (LSMGO). VLSFO futures contracts introduced in late 2019 and other energy‐related futures contracts indicate that the VLSFO contracts trading on the Singapore ...

Influence of Polymer and Rubber Modification on Fatigue Crack Propagation in Asphalt Mixtures: A Cyclic SCB and Paris Law Investigation

open access: yesFatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT Fatigue cracking is a major distress limiting asphalt pavement service life, and Paris law–based fracture mechanics offers a more mechanistic understanding than conventional fatigue testing. However, systematic characterization across diverse modifiers, dosages, notch depths, and temperatures remains limited.

ENABLING PARTIAL UPGRADING IN ALBERTA: A REVIEW OF THE REGULATORY FRAMEWORK AND OPPORTUNITIES FOR IMPROVEMENT

open access: yesThe School of Public Policy Publications, 2019
One of the ways that Alberta can help alleviate its worsening bottleneck in oilexport pipelines is by partially upgrading oil sands bitumen before shipping it to market.

Early development of anoxia prior to the main euxinic phase of the Jenkyns Event on the margin of the Western Tethys (Sachrang Basin, Eastern Alps)

open access: yesSedimentology, EarlyView.
ABSTRACT Although the global expansion of oxygen‐depleted marine environments during the Early Toarcian Jenkyns Event (or Toarcian Oceanic Anoxic Event) is primarily inferred from successions in the NW European epicontinental basins, the timing of the expansion of anoxia in Tethyan basins, where hydrography potentially played a minor role, is poorly ...

Salt Range Formation of Pakistan Preserves Unique Record of Volcanic Fertilization During the Ediacaran Shuram Excursion

open access: yesTerra Nova, EarlyView.
ABSTRACT Thin, discontinuous, organic‐rich oil shale beds in the siliciclastic‐evaporitic Salt Range Formation (SRF) of Pakistan are of approximate Neoproterozoic to Cambrian age based on stratigraphic constraints. The beds are enriched (26–43 wt.% total organic carbon, TOC) in aliphatic organic matter (OM) of low thermal maturity despite their ...

Influence of rejuvenators on bitumen ageing in hot recycled asphalt mixtures

open access: yesJournal of Traffic and Transportation Engineering (English ed. Online), 2018
The use of reclaimed asphalt pavement (RAP) in new hot mix asphalt (HMA) by means of hot recycling techniques generates the advantage linked to the exploitation of both lytic and bituminous component, consequently leading to the decrease of both virgin ...
