The graphical abstract illustrates a circular waste to value pathway in which coal fly ash is upgraded by isolating unburned carbon and converting it into functional carbon materials. Through carbonization and activation, UC‐derived carbon is transformed into high surface area electrodes for supercapacitors, supporting sustainable energy storage and ...

Asphalt pavement surface course with recycled rubber
After the end of their use in road traffic, car tires can be used in road construction as an addition to bitumen mixtures. By adding recycled rubber, bitumen properties are improved and better behaviour of placed asphalt is achieved (lower sensitivity to

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.%.

A novel multiphase composite was developed to prevent premature failure of waterproofing layers in pig houses. The system, comprising polyurethane, asphalt, and calcium carbonate, achieves a 1.35 MPa bonding strength and resists corrosion via a synergistic crosslinking, buffering, and passivation mechanism.

COMPARATIVE STUDY OF THE EFFECTS OF MODIFIED ASPHALT PAVEMENT USING NANO AND POLYMERS [PDF]
The global demand for bitumen has increased dramatically recently in spite of its complex production process, which has led scientists to use additives such as polymer materials or nanomaterials to develop bitumen's rheological and mechanical properties.

Relaxation Modulus of SMA with Polymer Modified and Highly Polymer Modified Bitumen
Abstract The article presents the test results of the relaxation modulus of SMA. The samples of SMA mixture were made using polymer modified bitumen PMB 45 / 80-55 (PMB-N) and highly polymer modified bitumen PMB 45 / 80-80 (PMB-HM). Determination of the relaxation modulus were made using DT-CY test (direct tensile test) at 10 °C, 20 °C and 40 °C.

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.

SELECTED PROPERTIES OF POLYMER-MODIFIED BITUMENS
The article presents an analysis of research results on bitumens modified with waste polymers polypropylene (PP) and polyethylene terephthalate (PET). The bitumens were modified under conditions consistent with the Plackett-Burman experimental design by appropriately selecting the mixing process variables. The results of basic tests are presented.

Influence of mineral fillers on the rheological response of polymer-modified bitumens and mastics
The rheological properties of the bituminous components (bitumen and bituminous mastic) within asphalt mixtures contribute significantly to the major distresses of flexible pavements (i.e. rutting, fatigue and low temperature cracking).
