TRB Webinar: Advanced Models to Characterize and Design Asphalt Pavements: Implementation and Application Examples

TRB Webinar: Advanced Models to Characterize and Design Asphalt Pavements: Implementation and Application Examples

TRB conducted a web briefing or "webinar" on October 12, 2011, that explored applications of advanced models to characterize, evaluate, and design asphalt pavements.  Presenters discussed the integration of material characterization and structural design to predict performance. Attendees learned more about laboratory experiments that could determine the parameters of mechanistic models and the influence of material characteristics and properties on these parameters. Model Qualification, Verification, Calibration, and Validation (QVCV) was also discussed.

Learning objectives: upon completion of the webinar, attendees will be able to:
•    Understand various computational and analytical models used in characterization and analysis of asphalt pavements;
•    Identify necessary material properties for various models; and,
•    Synthesize the laboratory testing requirements associated with material properties.

Presenters for this session include:

Y. Richard Kim
North Carolina State University
Application of Layered Viscoelastic Analysis and VECD Model to Fatigue Performance Evaluation of Asphalt Pavement
Brief Description: Introduction and applications of pavement fatigue performance prediction methodology using the Simplified Viscoelastic Continuum Damage (S-VECD) model and layered viscoelastic analysis.

Eyad Masad
Texas A&M University
Pavement Analysis Using Nonlinear Damage Approach
Brief Description: Introduction to the Pavement Analysis Using Nonlinear Damage Approach (PANDA) models and examples of using PANDA for predicting pavements performance.

Emin Kutay
Michigan State University
Practical Fatigue Characterization of Asphalt Mixtures using PP_VECD (Push-Pull test based Viscoelastic Continuum Damage analysis) Software
Brief Description: A step-by-step demonstration of PP_VECD software will be provided. Some example analyses using real data will be shown. PP_VECD software will allow users to compute fatigue lives at various temperatures and at various strain levels. The input to the software is |E*| master curve and push-pull (tension-compression) test data obtained at two different temperatures (at the same or different strain level).

Eshan Dave
University of Minnesota, Duluth
Thermal Cracking Prediction in Asphalt Pavements using Cohesive Zone Based Stand-Along Finite Element Program
Brief Description: Cohesive zone fracture model will be briefly introduced followed by framework of New Thermal Cracking Modeling Software (Graphical User Interface (GUI), Pre-processor and Finite Element Model). Finally verification and application examples will be demonstrated.

Moderated by Richard Steger, Majeska & Associates and Amit Bhasin, University of Texas, Austin
