The Asphalt Pavement Technology Program is an integrated, national effort to improve the long‐term performance and cost effectiveness of asphalt pavements. Managed by the Federal Highway Administration through partnerships with State highway agencies, Industry and academia the program’s primary goals are to reduce congestion, improve safety, and foster technology innovation. The program was est...

The environmental impacts of producing asphalt mixtures with different percentages of asphalt binder replacement (ABR) are assessed using the technique of life cycle assessment (LCA). In this paper, only the material production phase of the pavement life cycle is considered. To improve the quality of the LCA, a regionalized life cycle inventory (LCI) database for the Northern Illinois region is...

This paper describes the use of data mining tools for predicting the non-linear layer moduli of asphalt road pavement structures based on the deflection profiles obtained from non-destructive deflection testing. The deflected shape of the pavement under vehicular loading is predominantly a function of the thickness of the pavement layers, the moduli of individual layers, and the magnitude of th...

Asphalt road reflectance spectra change as pavement ages. This provides the possibility for remote sensing to be used to monitor a change in asphalt pavement conditions. However, the relatively narrow geometry of roads and the relatively coarse spatial resolution of remotely sensed imagery result in mixtures between pavement and adjacent landcovers (e.g., vegetation, buildings, and soil), incre...

Abstract This paper describes the development of novel/state-of-art computational framework to accurately predict degree binder activity a reclaimed asphalt pavement sample as percentage indirect tensile strength (ITS) using reduced number input variables that are relatively easy obtain, namely compaction temperature, air voids and ITS. Different machine learning (ML) techniques were applied ob...

This report provides a summary of the results of the various studies completed in the Partnered Pavement Research Program (PPRC) during the period 2000–2004. In addition, preliminary findings of investigations, initiated but not yet implemented during this period, are included. The results are based on the combined results of analytical developments, laboratory testing of pavement materials, an...

For the concerns of investigating viscoelastic properties recycled asphalt mixtures incorporating high content reclaimed styrene-butadiene-styrene (SBS) modified pavement (RAP-SBS), mixture performance tester (AMPT) was applied to analyze dynamic modulus and phase angle by influence RAP-SBS content, temperature, loading frequency, long-term aging (LOTA), incorporation a rejuvenating agent.
