Sustainable Material Solution for Flexible Pavements; Performance Evaluation and Impact Assessment of Utilizing Multiple Recycled Materials in HMA
… drawbacks? This study evaluates the structural performance and environmental-economical cost and benefit by substituting one or a combination of three recycled materials in HMA. The three recycled materials are Recycled Asphalt Shingle (RAS), Municipal Solid Waste Incineration (MSWI) Bottom Ash, …

Effects of Prestress Level and Bond on the Behavior of Prestressed Concrete Pavements
… The early application of prestressed concrete pavements was in the mid 1940's but its progress was slow compared with the other types of rigid pavements. Performance of the early build prestressed concrete pavements and advancements in construction technology as well as the ever increasing …

Comparative analysis between MERRA and updated MEPDG climate database in the state of Tennessee
… the effect of climate inputs on pavement performance. However, it requires detailed climate inputs, which might not be available for most of the state DOT. The Updated AASHTOWare climate database encompasses twelve stations in the state of Tennessee, which might not well represent all …

Sensitivity analysis and calibration of the alligator cracking model in the mechanistic-empirical pavement design guide using regional data
… impact of these regression constants on pavement performance and their variability with different pavement properties and parameters. The final aim of this study is to calibrate and validate the alligator cracking model for the state of New Jersey using these twenty nine sections spread across the …

Investigation of compaction characteristics of subbase material using the superpave gyratory compactor
… tool for the prediction of airport pavement performance and design. The practicality of the SGC was based on extensive laboratory and field testing of three unbound materials including P-154, P-209, and DGA, which are the subbase and base materials used by the FAA at the National Airport …

Validating the empirical distress prediction models within the AASHTOWare Pavement Mechanistic-Empirical Design, using Tennessee pavement performance data from the Long Term Pavement Performance database
… prediction models using Tennessee pavement performance data from the Long Term Pavement Performance (LTPP) database, along with previously established local and current global calibration coefficients. Findings from statistical evaluations support the need for local calibration and …

Correlation between multiple stress creep recovery (MSCR) results and polymer modification of binder
… which can improve both low and high temperature performance, is already available; however, but in many cases traditional Superpave testing is not sensitive enough to quantify the impact of modification, dimensioning its use. Superpave Performance Grade Plus tests, are sensitive to polymer …

Characterization of traffic load and local calibration of the MEPDG for New Mexico
… The influence of axle load spectra on pavement performance is predicted using MEPDG. For the sections analyzed, it is shown that the effect of axle load spectra is very high on fatigue cracking, moderate on permanent deformation, and non-existent on thermal cracking and roughness. In this study, …

Performance-based evaluation of unbound aggregates affecting mechanistic response and performance of flexible pavements
… layers. Their primary function in flexible pavements is to distribute wheel loads and provide adequate protection of the subgrade. However, the empirical strength based quality evaluations and current “recipe-based” specifications have little direct consideration of the actual performance of …
