Removal of rubber, bitumen and other microplastic particles from stormwater by a gross pollutant trap - bioretention treatment train.

Water Research, 2021
Microplastic particles in stormwater pose significant threats to the environment. This study investigated how effective a stormwater treatment train was at removing rubber, bitumen and other microplastics (incl. fibers, fragments, and paint particles) in

The problem of the compatibility of bitumen sheets for the reconstruction and ehabilitation of roofs [PDF]

MATEC Web of Conferences, 2017
During the renovation of flat roofs, the waterproofing layer is often repaired locally rather than completely replaced. When making such repairs, it is very important to know whether the proposed bitumen sheets are compatible in order to prevent ...

Multi-scale characterization of lignin modified bitumen using experimental and molecular dynamics simulation methods

Construction and Building Materials, 2021
Lignin, as a major waste from biofuel and paper industries, could be utilized as a modifier to enhance the relevant performance of bitumen. However, the effects of lignin on the thermodynamics properties and molecular structure of bitumen are rarely ...

Influence of selected reactive oxygen species on the long-term aging of bitumen

Materials Structure, 2022
The aging of bitumen is a major contributor to the failure of asphalt pavements. Realistic and accurate laboratory aging methods can predict bitumen durability and guarantee the use of high-quality components in asphalt pavement.

Modeling percentages of cohesive and adhesive debonding in bitumen-aggregate interfaces using molecular dynamics approaches

Applications of Surface Science, 2022
When an asphalt mixture cracks, adhesive debonding occurs along bitumen-mineral interfaces and cohesive debonding occurs within bitumen films. At microscale, the two debonding processes can happen simultaneously but it is unknown for their percentages ...
