Influence of foaming water and aging process on the properties of foamed asphalt
Construction and Building Materials, 2017Abstract Foamed asphalt is a good technique to reduce energy consumption and protect environment by decreasing the construction temperature of asphalt mixture. Many efforts have focused on the original foamed asphalt such as foaming characteristics and rheological properties, but how the performance of samples at different aging stages changing has ...

Mix design procedure for foamed asphalt mixtures
Road Materials and Pavement Design, 2016Mechanical foaming is the most popular method for producing warm mix asphalt in the United States; yet, a standard mix design procedure for foamed asphalt mixtures has not been established. Currently, the design of foamed asphalt mixtures consists of determining the optimum binder content by following a standard hot mix asphalt (HMA) design procedure ...

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.
