Memory functions in polymer modified asphalts

Journal of Applied Polymer Science, 2007
AbstractThe viscoelastic nonlinear behavior of several base and polymer modified asphalts (PMA) has been studied in step‐strain experiments. The polymers were poly(styrene‐b‐butadiene‐b‐styrene), poly(styrene‐b‐ethylene‐co‐butylene‐b‐styrene), poly(ethylene‐r‐vinylacetate) copolymers, and a linear low density poly(ethylene), which were chosen as ...

Polymer modified asphalt binders

Construction and Building Materials, 2007
Abstract This paper is a review of research that has been conducted on polymer modified binders over the last three decades. Polymer modification of asphalt binders has increasingly become the norm in designing optimally performing pavements, particularly in the United States, Canada, Europe and Australia.

Polymer Modified Asphalt Binders

1992
Description Peer-reviewed papers discus the use of elastomers such as styrene block copolymers, latex rubber, and various plastomers that include EVA and polyethylene. In 2 sections: laboratory studies of polymer modified asphalt binders for it mix asphalt; and emulsions and full scale field experiments which explore construction aspects

Creep Compliance of Polymer-Modified Asphalt, Asphalt Mastic, and Hot-Mix Asphalt

Transportation Research Record: Journal of the Transportation Research Board, 2003
The possibility of using commercial rheometers for comprehensive testing of asphalt binders, asphalt mastics, and hot-mix asphalts (HMA) is explored. Samples of one polymer-modified asphalt, its mix with fine mineral filler (mastic), and one HMA prepared with the same modified asphalt as binders were tested in the dynamic shear rheometer (DSR) and the

Highly Modified Asphalt Binder for Asphalt Crack Relief Mix

Transportation Research Record: Journal of the Transportation Research Board, 2017
Reflective cracking is a common issue with respect to rehabilitated asphalt pavements, especially when the rehabilitation is done by applying a hot-mix asphalt overlay on the existing damaged pavement. Several approaches can be adopted to delay reflective cracking.

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 ...

Long Lasting Asphalt Materials with Highly Modified Asphaltic Binder

2020
On mature road networks, there is a constant need for long-term pavement preservation solutions. In the 1980s, SBS polymer brought a breakthrough technology with superior performance for surface layer. In more recent years, highly modified asphaltic binder, HiMA, took a step further for structural layers with fatigue resistance.

Compound Modified Asphalt Performance Research

Advanced Materials Research, 2012
The scrap rubber powder and the waste plastic compound modified bituminous mixture are used in the first-class highway asphalt concrete pavement. They can not only reduce the environment pollution, but also enhance the operational performance of bituminous pavement. It has the economical, social and the environment three aspect remarkable benefit. This
