RISLaboratory and Field Evaluation of a Novel Cement Grout Asphalt Composite
Publisher: American Society of Civil Engineers
Abstract: The novel cement grout asphalt composite (CGAC) in this study is a new semiflexible composite consisting of open-graded hot mix asphalt (HMA) filled by injecting cement grout materials. The mechanical performance and ...
Dynamic Behavior and Performance Analysis of Asphalt Pavement in Areas with Extreme Seasonal Variation in Temperature
Publisher: American Society of Civil Engineers
Abstract: This paper describes a three-dimensional finite element (FE) model analysis to predict the viscoelastic pavement responses to vehicular loading in areas with extreme seasonal variation in temperature. Two different kinds ...
Investigation of the Rheological Properties and Aging Behavior of Aged Asphalt Binder in a Dynamic Pore Water Pressure Environment
Publisher: American Society of Civil Engineers
Abstract: AbstractAsphalt pavements in rainy regions are prone to aging and moisture damage, which can
significantly impair the performance of asphalt binders. This study examines the rheological
properties and aging behavior of ...
Rheological Properties and Modification Mechanism of OLDPE–SBS High-Viscosity Modified Asphalt
Publisher: American Society of Civil Engineers
Abstract: AbstractTo enhance the compatibility of waste plastic [low-density polyethylene (LDPE)] with
asphalt, waste cooking oil was used to pretreat the LDPE, resulting in oil-based LDPE
(OLDPE). This OLDPE was then combined with ...
Investigation of the Relationship between the Mechanical Performance and Contact Structure Characteristics for Asphalt Concrete Using a Digital Image Processing Method and a Machine-Learning Algorithm
Publisher: American Society of Civil Engineers
Abstract: AbstractThe internal structure of asphalt concrete (AC) plays a crucial role in determining
its mechanical performance. However, current studies lack accurate assessments of
AC’s mechanical performance based on its internal ...
