Evaluation of waste cooling oil and European Rock Asphalt modified asphalt with laboratory tests and economic cost comparison

, 2021
The recycling of waste cooking oil (WCO) has attracted increasing interest while most research is connected to fuel and bio-lubricant production. The study aims to extend the possibility of applying WCO in asphalt modification to achieve environmental ...

High-viscosity modified asphalt mixtures for double-layer porous asphalt pavement: Design optimization and evaluation metrics

, 2021
Porous asphalt mixture has been extensively exploited as a surfacing layer on highways because it contributes to controlling pavement runoff, enhancing driving safety, mitigating urban-heat island, and reducing tire-pavement noise.

Rheological, healing and microstructural properties of unmodified and crumb rubber modified asphalt incorporated with graphene/carbon black composite

Construction and Building Materials, 2021
Graphene, featuring excellent mechanical, electrical, thermal, and optical properties, has received increasing attention in asphalt modification. However, high production costs and poor dispersibility used in asphalt binders have limited its large-scale ...

Composite Asphalt Binders: Effect of Modified RPE on Asphalt

Journal of Materials in Civil Engineering, 2000
This study prepared and characterized recycled polyethylene (RPE) modified asphalts. The RPE was modified with different copolymers before incorporating into the asphalt. A special morphology was found for this system. The RPE particles are highly swollen by asphalt. This morphology is attributed to physical interactions.

Outdoor aging of road asphalt and SBS modified asphalt

Frontiers of Chemical Science and Engineering, 2010
The process of performance degradation of road asphalt (RA) is regarded as aging. At present, better understanding of the thermal-oxidative aging of asphalt is achieved and the corresponding method to evaluate this process is developed; meanwhile, photo-oxidative aging (aging in an atmospheric environment, which is referred to as “outdoor aging” in ...

Development on recycling, aging simulation and regeneration methods of reclaimed styrene-butadiene-styrene modified asphalt

, 2021
To develop the recycling, aging simulation and regeneration methods of reclaimed styrene-butadiene-styrene (SBS) modified asphalt, the centrifugation method of reclaimed asphalt pavement (RAP) was first optimized.

Rheology of asphalts modified with glycidylmethacrylate functionalized polymers

Journal of Colloid and Interface Science, 2004
Asphalt is known to be a colloidal suspension in which asphaltenes are covered by a stabilizing phase of polar resins and form complex micelles that are dispersed in the oily maltenic phase. In order to enhance its mechanical properties (e.g., in road paving), asphalts are often loaded with polymeric materials, thereby obtaining blends that can have ...

Paving Asphalts with Modifying Additives

Chemistry and Technology of Fuels and Oils, 2003
The possibility of increasing the quality of paving asphalts by modifying them with an inexpensive, nontraditional additive — Kashpir slate softener with a significant content of resins and asphaltenes — is demonstrated. In the concentration of under 7 wt.

Microscopic performance of modified asphalt based on aging

, 2021
In order to clarify the effect of modified asphalt after thermal aging (aging for short) on asphalt pavement performance, five groups of asphalt samples were selected as research materials: matrix asphalt group, styrene-butadiene-styrene (SBS) group ...
