Pavement Design And Materials Research 2007-2009 Activities
This report documents the work that has been completed for the 2007-2009 time period. During the two-years time period, summary and recommendation reports were produced at the completion of each task and were submitted to ...
Evaluation of Nevada's HMA Mixtures Manufactured with Terminal Blend Rubber Modified Binders
The objective of this research effort is to compare the laboratory performance of Nevada’s HMA mixtures made with rubber modified asphalt binders with HMA mixtures made with polymer modified binders. Two Nevada HMA ...
Variability Of The Moisture Sensitivity Of Field HMA Mixes
The objective of this study is to evaluate the variability in moisture sensitivity of lime treated HMA mixes that were sampled during construction from three projects located in the Truckee Meadows region.
Evaluation of Rehabilitation Techniques for Flexible Pavements in Nevada
The Nevada Department of Transportation (NDOT) is responsible for the maintenance and rehabilitation of a large number of highway miles which fit within the categories of medium to low traffic volumes. The majority of these ...
Design and Construction of NDOT PG-Special Test Sections
In 2000, NDOT constructed three sections on I-15 in Clark county, Nevada, as part of contract 3000. The objective of the test sections was to evaluate the field performance of HMA mixtures designed with binders graded with ...
Impact of Construction Variability on Pavement Performance: Report II
The objective ofthis research was to evaluate the impact of construction variability in aggregate gradation, binder content, and in-place air-voids, on the performance of HMA pavements. The performance of HMA pavements was ...
Evaluation of New Pavement Technologies in Nevada
This report documents the performance of new rehabilitation technologies of highway pavements in Nevada. A total of five new technologies were evaluated: four for flexible pavements and one for rigid pavements. The ...
Asphalt Concrete Anti- Stripping Techniques (executive summary)
In 1999 the South Dakota Department of Transportation initiated a research project to assess asphalt concrete anti-stripping techniques. The overall objective of the research was to evaluate the effectiveness of anti-stripping ...
Effect of Crumb Rubber Particle Size and Content on the Low Temperature Rheological Properties of Binders
This paper presents a study to evaluate low temperature rheological properties of crumb rubber modified binders and the impact of the particle size and content on such properties. Three sizes of the crumb rubber (0.18, ...
Evaluating The Impact Of Lime On Pavement Performance (Draft Final)
The purpose of this project is to quantify expected changes in pavement life from adding lime to hot mix asphalt (HMA) based on an extensive laboratory testing program and advanced mechanistic analyses. This research differs ...
