Abstract: Dynamic modulus

Abstract: A method has been developed using gel permeation chromatography (GPC), also known as size exclusion chromatography (SEC), for examining extracted material from fine aggregate to identify asphalt contamination within the ...

Abstract: This paper presents the results from a laboratory study in which hot-mix asphalt (HMA) mixtures with No. 4 sieve screened reclaimed asphalt pavement (RAP) were characterized for their cracking resistance through laboratory ...

Abstract: An asphalt mixture generally behaves as an insulator. The addition of electrically conductive additives may produce conductive asphalt mixtures. The present study investigated the effectiveness of several commonly used ...

Abstract: Heterogeneous air void distribution is a common phenomenon in asphalt mixtures and is intimately related to the behavior of the asphalt mixture. Air void distribution within an asphalt mixture specimen is related to several ...

Abstract: Thermal cracking of Portland cement concrete (PCC) decreases rideability and accelerates deterioration of concrete pavements. Coefficient of thermal expansion (CTE) is one of the most important parameters to evaluate the ...

Abstract: Although widely used by state Departments of Transportation (DOTs) and other highway agencies for characterization of rut resistance and moisture susceptibility of asphalt mixtures, loaded wheel testers (LWTs) are rarely ...

Abstract: The asphalt paving industry has been increasing the use of recycled asphalt pavement (RAP). There is a concern about the percentage of aged asphalt binder in the RAP that can actually be blended into the virgin binder and ...
