Graphene-Enhanced Recycled Asphalt Pavements

2019
100% Italian innovation: a new graphene-enhanced super-modifier (GESM) developed by Iterchimica Srl. In November 2017, the three-year-long research ended with a patent filing. This is the evolution of the traditional Polymer Modified Asphalt (PMA - dry method) technology and it consists of polymeric compound additivated with graphene.

Impact of recycled asphalt pavement material variability on pavement performance

Road Materials and Pavement Design, 2014
In recent years, recycled or reclaimed asphalt pavement (RAP) has been used increasingly due to its advantages in building sustainable pavement infrastructure. In the meantime, concerns have been raised regarding the performance of mixtures involving RAP.

Pavement Subgrade Stabilization Using Recycled Materials

Airfield and Highway Pavements 2015, 2015
The performance of subgrade stabilization with cement, lime or lime/fly ash are extensively studied. However, the use of recycled materials for subgrade stabilization is yet to be properly studied. If proper mix designs and construction specifications for subgrade stabilization with recycled materials are available, those materials can be used for ...

Recycling Dredged Sludge in Asphalt Pavement

Journal of Materials in Civil Engineering, 2014
An experimental investigation of an innovative recycling method to reuse dredged sludge in asphalt pavements is presented. According to this method, semifinished products or agglomerates, made of dried sludge and bitumen, are produced. These products may be used to partially substitute fine sand and bitumen in the asphalt mix.

Creep of compacted recycled asphalt pavement

Canadian Geotechnical Journal, 2007
Recycled asphalt pavement (RAP) can be beneficially used as fill in the construction of earth structures such as embankments and retaining structures. Experiments were conducted to evaluate the creep response of compacted RAP under sustained deviatoric stresses.

Recycling Flexible Pavements with Cement: Diverse Methods Produce Durable Pavements

Soil-Cement and Other Construction Practices in Geotechnical Engineering, 2000
Thousands of miles of existing flexible pavements throughout the U.S. are deteriorating. Street and highway departments continually seek economical, yet durable ways to rehabilitate their rutted and pot-holed roadways. Many have chosen to recycle the worn flexible pavements with cement.

Recyclability of Moisture Damaged Flexible Pavements

Journal of Materials in Civil Engineering, 1993
Stripping has damaged some of South Carolina's asphaltic concrete pavements. It is not known whether the material properties of stripped asphalt pavement will allow its use for recycling. A field and laboratory study was initiated to investigate the feasibility of reusing moisture‐damaged asphaltic concrete; to determine the effects of antistrip ...

Dynamic Modulus of Recycled Pavement Mixtures

Transportation Research Record: Journal of the Transportation Research Board, 2016
Pavement recycling techniques have been shown to be effective for rehabilitating pavements by reducing environmental impacts, construction costs, and time. For various reasons, many highway agencies have not widely embraced these processes despite the demonstrated advantages.

Recycling Old Asphaltic Pavement with Sulfur

1978
Recycling asphaltic concrete pavements was investigated as a means of utilizing the asphalt and graded aggregates they contain and solving waste disposal problems. Discarded asphaltic concrete pavement materials from three sources in the Las Vegas, Nev. area were studied; each contained a different aggregate base material.
