Evaluation of asphalt pavement maintenance using recycled asphalt pavement with asphalt binders

Construction and Building Materials, 2023
Road maintenance projects require innovative, economical, and environmental solutions. This study evaluated recycled asphalt pavement (RAP) as a greener aggregate alternative to natural aggregate for the maintenance of asphalt concrete in flexible pavements.

Asphalt Pavements with High Reclaimed Asphalt Pavement Content

Transportation Research Record: Journal of the Transportation Research Board, 2014
Today's sustainability-driven systems require a product or process to be environmentally beneficial as well as cost-effective. This study used life-cycle cost analysis (LCCA) and life-cycle assessment (LCA) to consider the economic and environmental feasibility of using a high content of reclaimed asphalt pavement (RAP) in asphalt mixtures.

Asphalt quality and strength of asphalt pavements

Chemistry and Technology of Fuels and Oils, 1977
The selection of an asphalt for paving mixtures is governed by the need to provide adequate resistance to shifting and cracking of the pavement. The cracking resistance of an asphalt pavement can be judged (for example) by the magnitude of its maximum deformation (before breaking) in comparison with the design-allowable flexure of the pavement at 0 ...

Pavement Performance of Asphalt Surface Course Containing Reclaimed Asphalt Pavement (RAP)

Journal of Testing and Evaluation, 2012
Abstract Reclaimed asphalt pavement (RAP) provides many advantages. The performance of a provincial road with an asphalt surface course containing RAP in Zhejiang, China was evaluated. The surface course was prepared by central plant hot mix recycling and virgin asphalt concrete. An AC-13 was chosen as gradation design in all mixes.

Pothole detection in asphalt pavement images

Advanced Engineering Informatics, 2011
Pavement condition assessment is essential when developing road network maintenance programs. In practice, the data collection process is to a large extent automated. However, pavement distress detection (cracks, potholes, etc.) is mostly performed manually, which is labor-intensive and time-consuming.

Degradation behaviors of asphalt by microorganisms in asphalt pavement structure

Bioresource Technology
Pseudomonas and Bacillus are dominant microorganisms to widely distributes in asphalt pavement structure. Microbial degradation leads to asphalt aging, and causes its performance deterioration, reducing the durability of asphalt pavement. To better understand the degradation behaviors of dominant microorganisms on asphalt, and reveals their microbial ...

Cold Recycling of Reclaimed Asphalt Pavements

2018
Pavement engineers have in front of them multiple challenges linked to addressing issues related to social development and society’s expanding needs. One of the most substantial of these issues is perhaps how to effectively rehabilitate and/or maintain the existing road network while preserving and sustaining limited natural resources.
