Evaluation of Asphalt Foaming Characteristics
ICCTP 2011, 2011This study explores new and more convenient methods and indexes for characterizing foamed asphalt. First, a radioactive decay model was used for foamed asphalt, and a general equation was derived by differential methods for the actual maximum expansion ratio. The independent variables of the equation were the maximum measured expansion ratio, half-life

Lowering the Asphalt Production Temperature - Foam Asphalt Allows Greener Roads
Advanced Materials Research, 2013New technologies enable the manufacturing of asphalt at reduced temperatures. As a result The energy consumption per ton of asphalt and the emissions at the road construction site drop significantly. Whilst conventional asphalt is produced at around 170 ° C, the low - temperature processes of today allow production temperatures of around 100 ° C ...

Effect of laboratory foamer on asphalt foaming characteristics and foamed mixture properties
International Journal of Pavement Engineering, 2015AbstractIn the United States, mechanical foaming is the most popular method for producing warm mix asphalt, which is the latest technology implemented to reduce the production temperature and/or enhance the compactability of asphalt mixtures. Three commonly used commercially available laboratory foamers to produce asphalt foams include the Wirtgen WLB ...

Sensitivity of Nozzle-Based Foamed Asphalt Binder Characteristics to Foaming Parameters
Transportation Research Record: Journal of the Transportation Research Board, 2014Foam-based warm-mix asphalt technologies decrease the overall viscosity of the asphalt mixture at lower temperatures so that it is workable during construction. However, after construction, viscosity increases rapidly as the foam disappears and the temperature drops.

Failure Investigation of a Foamed-Asphalt Highway Project
Journal of Infrastructure Systems, 2006This paper documents an investigation into the cause of structural distress (alligator cracking and deep rutting) found in a foamed-asphalt warranty project in Texas. This is a unique forensic study involving a warranty specification, where the contractor may or may not be liable for the cost of repairs, depending on the outcome of the study. Extensive

Bitumen Chemical Foaming for Asphalt Paving Applications
Industrial & Engineering Chemistry Research, 2010As an alternative to traditional hot-mix asphalt paving, bitumen foaming technologies have been extensively used in road recycling over the last decades. However, much more work on the use of foam-enhancing chemical agents is needed. This research deals with the influence that temperature and processing protocol exert on the bitumen foaming process ...
