Effects of Asphalt Foaming on Damage Characteristics of Foamed Warm Mix Asphalt
Transportation Research Record: Journal of the Transportation Research Board, 2021In the asphalt foaming process, the foaming water content (FWC) controls the formation and characteristics of water bubbles. These water bubbles are expected to be expelled from the foamed warm mix asphalt (WMA) during mixing and compaction. However, foaming water may not be completely expelled, rather some of the microbubbles may be trapped in the ...

Applied Mechanics and Materials, 2013
In this paper, the structure of foam cavity which based on FB100 foamed asphalt testing machine will be analyzed and designed to change its volume. So that, the changes of work pressure about hot asphalt would be caused and the hot asphalt, water, gas would be more uniform contact to improve the effect of foaming properties about asphalt.

Experimental Study on Foaming Characteristics of Foamed Asphalt
Applied Mechanics and Materials, 2013This paper presents study on foaming characteristics of two types asphalt with same Penetration-grade 70. Asphalt temperature (AT), water content (WC) and water temperature (WT) were selected for investigation their effects on the asphalt foamability. Maximum expansion ratio (ERMax) and half-life (HL) are important indicators of foamed asphalt.

Influence of foaming on tribological and rheological characteristics of foamed asphalt
Construction and Building Materials, 2019Abstract The frictional characteristics of asphalt binder as a lubricant film in an asphalt-aggregate interaction play a major role in workability of warm-mix asphalt (WMA). However, no WMA research considered the frictional characteristics of asphalt to demonstrate the workability of WMA, rather most of the previous studies are limited to foaming ...

Transportation Research Record: Journal of the Transportation Research Board, 2015
Warm-mix asphalt (WMA) produced by foaming is widely used in the asphalt paving industry and is the largest segment of the WMA market in the United States. To produce foaming, a small quantity of cold water is injected into hot asphalt to cause a reduction in the asphalt viscosity and improve the coating of the aggregate particles.
