Bridge Deck Condition Rating Forecast—Survival-Based Models

Raka Goyal, Ph.D., P.E.

Introduction

The survival-based models on Federal Highway Administration (FHWA) InfoBridge^TM (FHWA, 2020) are probabilistic bridge deterioration models based on a methodology that combines...

Bridge Deck Condition Rating Forecast—Base Models

Base models are deterministic statistical models that are easy to understand and implement. With base models, historical time duration for each deck condition rating of selected types of bridges is calculated from training subsets of the National Bridge Inventory (NBI) (Federal Highway...

Structures

The Federal Highway Administration (FHWA) Structures Research and Technology (R&T) Program focuses on providing tools, technologies, and guidance, and support for updated policies. The goal of the program is to improve the safety, structural integrity, longevity, construction...

Long-Term Infrastructure Performance

The Long-Term Infrastructure Performance (LTIP) Programs include the Long-Term Pavement Performance (LTPP) Program and the Long-Term Bridge Performance (LTBP) Program. These programs, conducted in collaboration with the State department of transportation infrastructure owners,...

Geotechnical Engineering

The FHWA Geotechnical Engineering Research Program is a key part of the overall Geotechnical and Hydraulics Research and Technology (R&T) Program which provides a coordinated and cohesive approach to research, development, and technology activities to improve the geotechnical and hydraulic...

Laboratory Equipment

The Federal Highway Administration’s (FHWA’s) Advanced Sensing Technology (FAST) NDE Laboratory houses state-of-the-art NDE equipment to support FHWA’s strategic vision and to provide training to stakeholders who maintain and manage transportation infrastructure such as bridges, pavements,...
