Effect of Asphalt Rejuvenating Agent on Aged Reclaimed

Unlike the softening techniques, the rejuvenating agent restores the chemical structure of aged asphalt by providing lost aromatic constituents and reduces the overall viscosity of the binder. Different types of commercial rejuvenators (CRs) have been recommended for higher percentages of RAP, especially for more than 30% [ 5

Environment-Friendly Construction Materials. Construction materials are the most widely used materials for civil infrastructure in our daily lives. However, from an environmental point of view, they consume a huge amount of natural resources and generate the majority of greenhouse gasses. Therefore, many new and novel technologies for designing

Asphalt compositions comprising reclaimed asphalt and an ester-functional rejuvenating agent derived from tall oil are disclosed. Rejuvenated binder compositions are also included. The rejuvenating agents restore to reclaimed asphalt desirable properties of asphalt. Reduced glass-transition onset temperatures and improved creep stiffness in the rejuvenated binders translate to improved

Effects of Recycling Process on Performance-Related Properties of Recycled Asphalt Mixtures Before and After Ageing Dissertation zur Erlangung eines Doktorgrades

The Guide to Pavement Technology Part 4B: Asphalt provides an introduction to the nature of asphalt as a material and its application in road pavements.. Asphalt is widely used in the construction and surfacing of roads in Australasia. The properties of asphalt are complex and its performance requirements vary considerably with the application.

rejuvenating agent having an adverse effect on the new bitumen, reclaimed asphalt pavement (RAP) was firstly treated by the rejuvenating agent, and the effect of rejuvenating time on the pavement properties of CRMB was investigated. Results indicate that the addition of a rejuvenating agent

Waste engine oil (WEO) as a rejuvenating agent is used to restore aged asphalt of different aging degree and the effect of WEO on the reclaimed properties is investigated. The results indicate that WEO can make the properties of aged asphalt restore. The mixing amount of WEO increases with the aging degree. For the asphalt sample which aged for 5h, 2% of mixing amount can make the penetration

Blending between aged and new binders can be affected by the chemistry of the asphalt binder. • FAM test can capture the difference between binder grades. • RAP/RAS content and use of a rejuvenating agent were statistically significant factors that affect the shear stiffness of FAM mixes. 24

Project Objectives. The purpose of this research is to perform a systematic study of the observed RAP rejuvenating properties that the soy-based dust control agent exhibited during our field trials. The tests will be conducted in the asphalt research lab at NDSU and will include fresh asphalt as a standard for comparison.
