Development of Two-Phase Diffusion Model Consisting of Free and Bound Water Molecules for Water Vapor Diffusing into Asphalt Mixtures
Publisher: ASCE
Abstract: Water vapor diffusing inside asphalt mixtures is one of the most important ways for water molecules accessing asphalt mixtures to trigger moisture damage. Several diffusion models have been constructed to describe the water ...
Influence of Infiltration Velocity on the Measurement of the Surface Energy Components of Asphalt Binders Using the Wilhelmy Plate Method
Publisher: ASCE
Abstract: Two common test methods measure the surface energy of asphalt binders: the Wilhelmy plate method and the sessile drop method. In contrast to the sessile drop method, the Wilhelmy plate method introduces the influence of ...
Moisture Content Prediction Model of Asphalt Mixtures Based on Dielectric Properties
Publisher: ASCE
Abstract: Moisture damage is one of the important factors affecting the service performance of asphalt pavement. Therefore, the use of nondestructive testing methods to detect the moisture content of asphalt pavement and provide a ...
Evaluation of Moisture Sensitivity of Asphalt Mixtures Based on Surface Energy of Asphalt Mastic
Publisher: American Society of Civil Engineers
Abstract: The properties of asphalt mastic are crucial in determining the moisture sensitivity of asphalt mixtures, but the adhesion performance of the mastic has not been quantitatively described. To address this gap, this study ...
Development of Relative Humidity–Frequency Equivalence Principle for the Dielectric Properties of Asphalt Mixtures
Publisher: ASCE
Abstract: Asphalt pavement contains dynamically changing moisture, and the movement of this moisture will change the relative humidity of the pavement, thereby affecting the dielectric properties of the asphalt mixture. To improve ...
