Experimental evaluation of anti-stripping additives on porous asphalt mixtures [PDF]

open access: yes, 2015
The open structure of porous asphalt mix influences its strength and durability against air, water and clogging materials. These factors cause loss of adhesion between binder-aggregate interface and loss of cohesion within the binder film.

Leveraging Life Cycle Assessment for Informing Packaging Eco‐Design and Eco‐Modulation

open access: yesSustainable Development, EarlyView.
ABSTRACT Eco‐modulation is designed to promote the adoption of eco‐design. However, in practice, its application is mostly concentrated on end‐of‐life (EoL) optimization. This study addresses the gap by proposing a framework to assess product–packaging systems as integrated units throughout the full life cycle.

Digital Roots or Digital Routes? Broadband Expansion and the Rural‐Urban Migration in China

open access: yesPopulation and Development Review, EarlyView.
Abstract This study investigates how broadband internet affects rural–urban migration in China using the Universal Broadband and Telecommunication Services pilot program launched in 2015 as a quasi‐experimental setting. Analyzing China Household Finance Survey data (2013–2021) with difference‐in‐differences estimation, we find that improved internet ...

Influence of cationic asphalt emulsion on the water transportation behavior and durability of cement mortar

open access: yesCase Studies in Construction Materials, 2022
Cement asphalt mortar (CAM) could be considered as the cement mortar modified by asphalt emulsion, which would alter the microstructure of cement mortar and thus exert significant influence on the mechanical properties and durability of CAM.

Asphalt Cement Containing AC-13, HR-522, Final Report, 1988 [PDF]

open access: yes, 1988
Stopping and turning maneuvers on high traffic volume asphalt cement concrete surfaced roads and streets often cause distortion of the pavement. Distortion may show up as excessive rutting in the wheel path, shoving of the pavement and/or rippling of

Terrestrial Analogs to Titan for Geophysical Research

open access: yesReviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Saturn's moon Titan exhibits remarkable parallels to the Earth in many geophysical and geological processes not found elsewhere in the solar system at the present day. These include a nitrogen atmosphere with a condensible gas—methane—replacing the Earth's water, leading to an active meteorology with rainfall and surface manifestations ...
