Aging of asphalt binder in hot pavement rehabilitation ...

2018-10-30  The thermal history of an asphalt mixture, already from the initial mixing and placement processes, influences its mechanical performances and durability, since its reduction to thin film and high mixing temperatures (primary aging or short term-aging) and pavement in-service oxidation (secondary aging or long-term aging) accelerate the aging processes of asphalt binder, which tend to lose cohesion and ductility through a general stiffening .

Early Preventive Maintenance Extends Asphalt Pavement

2017-3-21  Early Preventive Maintenance. Extends Asphalt Pavement Life. What Was the Need? As asphalt pavements age, the asphalt cement that binds . the aggregate oxidizes, making the pavements more brittle and susceptible to cracking and other deterioration. To help mitigate this process, MnDOT periodically conducts preventive maintenance using surface treatments.

2018-10-2  Investigation of Aging Behavior of Biorejuvenated Asphalt with Chemical and Micromechanical Methods (Received 30 December 2017; accepted 3 May 2018) ... Considering the increased application of high reclaimed asphalt pavement (high RAP) content mixtures, the biorejuvenator attracts increasing attention during the pavement maintenance and ...

Evaluation of Binder Aging and Its Influence in Aging

Evaluation of Binder Aging and Its Influence in Aging of Hot Mix Asphalt Concrete. Asphalt binders oxidize in pavements, even well below the pavement surface. This oxidation is ongoing throughout the life of the pavement and leads to ever-increasing binder embrittlement and reduced pavement durability.

Asphalt Maintenance – Corrective Asphalt Materials

Asphalt is made up of two components - asphaltenes and maltenes. The asphaltenes are the bonding agent that make the asphalt hard while the maltenes give it its stickiness. When asphalt loses its maltenes, the road surface becomes dry and brittle. This leads to raveling, pitting, cracks, potholes and other signs of aging.
