Developing An Alternative Hardened Concrete Air Void Characterization Method
This study presents the development and analysis of an alternative characterization method for the hardened air void system in concrete. This study uses ASTM C457, “Standard Test Method for Microscopical Determination of Parameters of the Air-Void System in Hardened Concrete” as a baseline …

Analysis of air-void system in hardened concrete from a three-dimensional perspective
… can be greatly enhanced by entrainment of small air bubbles in the cement paste. When the volume and distribution of the entrained air is properly controlled, the microstructure is protected from pressure exerted by freezing water. ASTM C457 “Standard Test Method for Microscopical Determination …

Local calibration of the MEPDG prediction models for pavement rehabilitation and evaluation of top-down cracking for Oregon Roadways
… tests on asphalt binder and aggregate gradation analysis. The FWD and DCP tests indicated that top-down cracked pavement sections were structurally sound, even some of the sections with top-down cracking showed better structural capacity compared to non-cracked sections. The study also found that …

Fractionated reclaimed asphalt pavement as a coarse aggregate replacement in a ternary blended concrete pavement
… dosages), the unit weight decreased, and the air content remained relatively unaffected although somewhat more variable. A hardened air void analysis revealed acceptable parameters for freeze/thaw durability, but the hardened air content was found to be higher than measured volumetric fresh …
