Effect of Interlayer Bonding Temperature on the Bending Properties of Asphalt Concrete Core Wall. [PDF]
Materials (Basel), 2023 In the construction process of an asphalt concrete impermeable core wall, the interlayer bonding of the core wall is the weak link of the core wall structure and also the focus of construction, so it is important to carry out research on the influence of interlayer bonding temperature on the bending performance of an asphalt concrete core wall. In this

Stress-Strain Analysis of Aikou Rockfill Dam With Asphalt-Concrete Core
Journal of Rock Mechanics and Geotechnical Engineering, 2011 AbstractAikou rockfill dam with asphalt-concrete core is situated in a karst area in Chongqing City, China. In order to study the operative conditions of the rockfill dam, especially those of the asphalt-concrete core, the Duncan model is adopted to compute the stress and strain of both the rockfill dam and the asphalt-concrete core after karst ...
