Hydrogen‐powered aviation offers a transformative pathway to zero‐emission flight by eliminating in‐flight CO2 emissions. Key considerations include propulsion systems (fuel cells and hydrogen combustion), cryogenic storage and insulation challenges, infrastructure and cost barriers, and supply‐chain constraints.

Factors influencing the strength of foamed bitumen stabilised mix [PDF]
Recycling of asphalt pavements has increased significantly since 1970 and in Malaysia the use of foamed bitumen as stabilizing agent was first introduced in year 2001.

Evaluation of factors influencing strength of foamed bitumen stabilised mix [PDF]
Over recycling of asphalt pavements involves mixing of existing pavement material with stabilizing agent such as foamed bitumen, bitumen emulsion, cement or lime and placed on the milled pavement and compacted.

Warm Mix Asphalt (WMA) evaluated using different stiffness modulus measuring methods [PDF]
This study evaluates and compares the results of two distinct stiffness measurement methods – Direct Cyclic Compression test (DCC) and Indirect Tensile test (IT-CY) – applied to warm mix asphalts (WMA) reinforced with basalt fibres intended for the ...

Foamed Bitumen Characterization Techniques
In soil stabilization and pavement recycling, the expansion ratio and half-life parametershave been considered to defne foamed bitumen quality relatively well. However, when applyingfoamed bitumen technology in the production of warm mixtures, these properties are determinedto be insufcient to characterize the foam and guarantee complete aggregate ...

ABSTRACT Under low reagent dosage, the flotation performance of diesel as a collector was enhanced, and the synergistic mechanism of diesel blended with oleic acid and CTAB was investigated. Results showed that compared to pure diesel, the oleic acid blended system (Blend A) increased clean coal yield by 81.52% to 92.24%, while the CTAB blended system (

Stiffness Evolution of Granular Materials Stabilized with Foamed Bitumen and Cement
From the literature, it is possible to find two trends regarding the stiffness evolution of foamed bitumen stabilized recycled mixtures. The first trend indicates that once the foamed bitumen mix reaches a constant value because of the curing process ...

Direct Ink Writing 3D Printing of Recyclable and Thermally Stable Vitrimers
Vitrimers hold great promise in additive manufacturing as defect‐insensitive, repairable, and recyclable feedstocks. A thin‐film additively manufactured process is developed for a high‐performance vitrimer that is difficult to process traditionally.
