Influence of base asphalt aging levels on the foaming characteristics and rheological properties of foamed asphalt

Construction and Building Materials, 2018
Abstract Foamed asphalt technique is widely used in road construction due to its environmental and economic effects. The various characteristics of foamed asphalt and mixtures have already been investigated; however, few studies focused on what happened on the properties of foamed asphalt when the base asphalt was aged at different degree.

Effects of Asphalt Foaming on Damage Characteristics of Foamed Warm Mix Asphalt

Transportation Research Record: Journal of the Transportation Research Board, 2021
In 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 ...

The Influences of the Volume in Asphalt Foam Device on Foaming Asphalt Characteristics in Cold Foam Asphalt Recycling Equipment

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, 2013
This 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.
