AGING SUSCEPTIBILITY AND PERFORMANCE OF OIL MODIFIED ASPHALT BINDERS
Kilger, Albert (2018)As oils are becoming more popular additives in asphalt binders as low temperature modifiers, there has been interest in the performance, especially the long-term aging, of oil modified asphalts. Research studies have ... -
AN ALTERNATIVE METHOD FOR MEASURING PERMANENT DEFORMATION OF HOT MIX ASPHALT MIXTURES
Lemke, Zachary (2018)More than twenty Department of Transportations are currently using a wheel tracking test to measure rutting resistance of mixtures that already meet volumetric properties (Buchanan, 2016). With the expansion of using ... -
CRITICAL ANALYSIS OF PH AND PG+ ASPHALT BINDER TEST METHODS
Lyngdal, Erik T. (2015-05-17)One of the principle products from the Stratigic Highway Research Program (SHRP) was the Superpave asphalt binder performance grading (PG) specification system. This system was based on fundamental engineering principles ... -
DEFINING EFFECTIVE AGGREGATE SKELETON IN ASPHALT MIXTURE USING DIGITAL IMAGING
Roohi Sefidmazgi, Nima (2011-12-15)Characterization of the asphalt mixture microstructure using two dimensional (i.e., 2-D) imaging techniques is an economically efficient approach. However, the features that have been captured and quantified using 2-D ... -
Development of the Loaded Wheel Tracking Test (LWT) for Evaluating Bleeding In Chip Seals and Relationship to Emulsion Residue Rheology
Chaturabong, Preeda (2014-08-22)State highway agencies (SHAs) lack sufficient to maintain the nation?s highway infrastructure. Most pavements have structural capacity, but lack serviceability functions as their surface characteristics have been lost with ... -
Effects of Oil Modification on Aging Characteristics of Asphalt Materials
Sylla, Ryan (2016-10-11)Thermal induced cracking of asphalt mixtures is currently recognized as one of the primary distresses of asphalt pavements in cold climate regions. Thermal cracking is caused by cold temperatures, which results in the ... -
Estimating Blending Level of Fresh and RAP Binders in Recycled Hot Mix Asphalt
Yousefi Rad, Farhad (2013-05-19)Despite all advantages of using Recycled Asphalt Pavement (RAP) in new HMA mixtures, the lack of a clear understanding of the nature, and more importantly, the rate of blending between fresh and RAP material has been a ... -
Modification of Multiple Stress Creep and Recovery Test Procedure and Usage in Specification
Golalipour, Amir (2011-12-15)Since the emergence of Superpave� equipment and specifications in the pavement industry in 1993, researchers and practitioners have found tools to understand characteristics and behavior of paving materials in better ...
