  • FlexMAT™ Asphalt Pavement Analysis Tools

FlexMAT suite of tools help with the characterization of cracking and rutting of asphalt pavements. FlexMAT for Cracking is a Microsoft® Excel-based analysis tool for characterizing dynamic modulus and cracking of asphalt pavement mixtures from Asphalt Mixture Performance Tester (AMPT) test results. This includes determining the 2S2P1D dynamic modulus master curve coefficients and time-temperature shift factors. It analyzes the AMPT cyclic fatigue test results (AASHTO TP133) to provide inputs to FlexPAVE™ cracking evaluation. These inputs include damage characteristic curve coefficients, failure criteria coefficients, ageing parameters, and the coefficient of thermal contraction. The analysis also supports balanced mix design and production evaluation by calculating the Sapp  index cracking parameter from the test data. FlexMAT for Rutting is an Excel-based analysis tool for characterizing rutting of asphalt pavement mixtures from AMPT test results. This includes analyzing the AMPT stress sweep rutting (SSR) test results (AASHTO TP134) to provide shift permanent deformation model coefficients to FlexPAVE rutting evaluation. The analysis also supports balanced mix design and production evaluation by calculating the Rutting Strain Index (RSI) parameter from the test data.

  • Best Practices to Publish in Pavement Science and Engineering

Academy of Pavement Science and Engineering (APSE) released these guidelines to identify and disseminate the best practices for publishing in pavement science and engineering community, especially for students and junior researchers. This effort was led by Dr. Zhen Leng from The Hong Kong Polytechnic University and assisted by Dr. Siqi Wang from Southeast University, Dr. Angeli Jayme from the University of Illinois at Urbana-Champaign, and Dr.-Ing. Miomir Miljković from the University of Niš.

  • Critical Works in Pavement Science & Engineering

During the last couple of years, an APSE task force of the Research Committee (RC- TF1) composed by more than 15 APSE members, from diverse backgrounds and expertise, has been working hard in building a database with the most critical works published in different areas of Pavement Science & Engineering. These activities, which have been conducted under the leadership of Prof. Shane Underwood, resulted in a comprehensive Zotero database or bibliographic catalog. This catalog is organized in six main areas:

  1. Pavement and Asset Management,
  2. Pavement Construction,
  3. Pavement Foundations,
  4. Pavement Materials,
  5. Pavement Structure, and
  6. Sustainability.

This database has been released by APSE! Version 1.0 can be accessed here: PS&E bibliographic references database
