Register NowEffect of Moving Dynamic Loads on Pavement Response and Performance Part I: Deflections and Backcalculated Modulus

July 22, 2020 | 12-1PM EST

Traditionally, analysis of pavement deflections or backcalculation of layer parameters from moving load data (such as those from Traffic Speed Deflection Devices, TSDD) has typically been conducted with the assumption that the load generated by the vehicle is constant with a magnitude equal to the instantaneous load. This webinar will discuss the relevant efforts in quantifying the effect such assumption on the simulated deflection basin and the backcalculated layer moduli. First, the presentation will discuss different methodologies (i.e., Fixed Point Analysis versus Moving Frame Analysis) for simulating the pavement deflections under a moving load. Then, examples will be provided to demonstrate the effect of dynamic loads on pavement deflections and backcalculated results, based on simulation results obtained from Moving Frame Analysis methodology coupled with a mechanical vehicle model.

Learning Outcomes:

  • Understand the difference between Fixed Point and Moving Frame analysis methodologies for pavement deflection and response simulation.
  • Understand the effect of dynamic loads on pavement deflections and backcalculated moduli.

Register NowEffect of Moving Dynamic Loads on Pavement Response and Performance Part II: Pavement Performance

August 19, 2020 | 12-1PM EDT

In this webinar, a methodology will be introduced for Mechanistic-Empirical prediction of International Roughness Index (IRI). The methodology utilizes a full, 3D truck-trailer model for simulating the vehicle dynamic load and the Moving Frame Analysis methodology for simulating the pavement response as well as the spatially varying depth values. The nonhomogeneous rut depth is then used to update the pavement surface profile from which the IRI is evaluated again. The webinar will also provide simple examples comparing the mechanistic-empirical IRI results against those from an empirical model.

Learning Outcomes:

  • Understand the difference between Mechanistic-Empirical IRI prediction versus purely empirical IRI prediction.
  • Understand advantages and disadvantages of Mechanistic-Empirical IRI prediction for practical use in pavement design and analysis.

Register NowProbabilistic Safety Analysis and Friction Management

September 23, 2020  |  12-1PM EST

Safety performance is a crucial component of a highway network performance evaluation. Due to the complexity and variability of traffic crash events, specialized statistical and engineering analyses are required to assess the safety performance of highway segments. In the AASHTO’s Highway Safety Manual (HSM) safety performance functions (SPFs) derived using count data models are used to predict and characterize the safety performance both at the network level and also for individual sites.

The first part of this webinar will provide an overview of the statistical procedures and interpretations to develop and calibrate SPFs. This part will also include a more detailed probabilistic interpretation of these SPFs to help devise an objective risk analysis for safety evaluation and decision making under uncertainty.

The second part of this webinar will provide an overview of the current practice and state of the art in pavement friction evaluation and its impact on highway safety performance; and identify current gaps in evaluating the impact of pavement friction on traffic safety at individual sites.

Register NowPavement Response to Superheavy Load Movement

October 21, 2020 |  12-1PM EST

With rapid growth and development of urban cities, rural areas have become primary focus for setting up industrial plants. Depending on the type of facility, major components may be fabricated at a fabrication plant and then moved to a plant location. Occasionally, these components are considered to be superheavy and organizing a secure and successful move from the fabrication plant to the final location becomes a necessity. There have been multiple research attempts to develop structural response models to predict pavement damage from superheavy loads. 

This presentation will summarize the methodology and results of various scenarios predicted and pavement inspection results prior to and after a successful superheavy move. To facilitate the move, several trials were completed with various scenarios. Due to the sophisticated nature of the project, finite element modelling was used to determine the pavement layer stresses and strains when subjected to superheavy load moves. 

Learning Outcomes:

  • Understand the effect of pavement impact due to the superheavy move on various pavement layers
  • Importance of pre- and post-move surveys to quantify the damage

Register NowAirport Pavement Management - Past, Present, and Future

November 18, 2020  |  12-1PM EST

This webinar will provide a brief history of the origins of airport pavement management systems (APMS), focus on the present state-of-the-practice, and discuss emerging technologies and FAA initiatives that will impact the future. The Pavement Condition Index (PCI) procedure will be discussed, as well as the pros and cons of various data collection methods such as: foot-on-ground, digital survey vehicle (DSV), LiDAR, and unmanned aerial vehicles (UAV). The aircraft classification number – pavement classification number (ACN-PCN) procedure used to assess the maximum aircraft weight a runway is able to support will also be covered.

Future APMS considerations such as roughness and friction will be covered as they relate to the overall goals of pavement management. In particular, the Boeing Bump Index (BBI) and current FAA initiatives to improve this index will be discussed. Lastly, a brief overview of future considerations will be discussed touching on topics including computer vision algorithms for pavement distress identification and potential applications for artificial intelligence.

Learning Outcomes:

  • The origins for airport pavement management systems and reasons to implement them
  • The current state-of-the-practice methods and technologies for PCI data collection
  • How to incorporate ACN-PCN results into a pavement management system
  • Emerging technology and FAA initiatives that may impact the future of airport pavement management
