Design and Construction of Resilient and Durable Concrete Pavements Subjected to Extreme Conditions

Sunday, March 24, 2024  3:30 PM - 5:30 PM, Strand 11B

The transportation infrastructure is the backbone of the global economy, connecting people, enhancing quality of life, and promoting health and safety. The structural integrity and durability of the infrastructure is vulnerable when subjected to extreme conditions such as flooding, fire, tornadoes, and sea level rise. This session will provide insight on designing and constructing resilient and durable highway and airfield pavements subjected to extreme conditions.

Learning Objectives:
(1) Define how resiliency concepts can be applied to concrete pavements;
(2) Describe the use of concrete overlays as a rehabilitation strategy to improve performance of existing roadways subjected to extreme weather damage;
(3) Identify various rehabilitation techniques exist to strengthen and harden the airfield pavement system;
(4) Quantify resilience in design and construction of concrete pavements.

This session has been approved by AIA and ICC for 2 PDHs (0.2 CEUs). Please note: You must attend the live session for the entire duration to receive credit. On-demand sessions do not qualify for PDH/CEU credit.


Improving Pavement Resiliency and Disaster Recovery: A Case for Concrete Pavements

Presented By: James Mack
Affiliation: CEMEX
Description: Future climate conditions are not going to resemble the past. Temperatures are going to get hotter and storms are going to get stronger. However, pavements are still being designed assuming that past conditions are going to resemble the future. This is a poor assumption. Furthermore, when climate change and pavement resilience are discussed, people often focus on the immediate and local impacts of the natural disaster, such as a washout during flooding. While this is important, one also needs to recognize that pavement damage can occur at over a broad area and over a long timeframe. That is, the pavement is damaged when it is first exposed to the natural disaster, such as a flood, and secondly after the disaster when rescue, emergency response and recovery activities are taking place and the pavement, often in a weakened state, is subjected to increased and heavier traffic due to clean up and rebuilding. This presentation will define how resiliency concepts can be applied to applied to pavements, using pavement flooding as an example. It will cover the need for the resiliency; define a resiliency framework to account for both initial and secondary impacts; will provide some approaches to mitigate pavement damage using concrete and cement-based products; and finally, it will describe process that could be used to assess different pavement resilience options.


Concrete Overlay Strategies for Improving Pavement Resilience

Presented By: Daniel King
Affiliation: National Concrete Pavement Technology Center
Description: Increases in flooding events and rising groundwater levels caused by climate change threaten to weaken pavement foundations, which can have a major impact on flexible pavement service life. Rigid pavements are not as sensitive to the strength of underlying layers, so one potential method to improve the resilience of vulnerable pavements is to construct concrete overlays. This presentation reviews an analysis of the potential for concrete overlays to improve the performance of existing roadways in flooded and inundated conditions and to serve as a cost-effective rehabilitation strategy in locations which experience high probabilities of flooding.


Designing for Improved Airfield Pavement Resilience

Presented By: Greg Dean
Affiliation: ACPA - Southeast Chapter
Description: Resilience is defined as the ability to endure or bounce back quickly from adverse conditions. Furthermore and relating to infrastructure, resilience is about being able to anticipate and adapt so that future events will have minimum impacts. The presentation will review portions of the FAA design circular (AC 150/5320-6G) to help illustrate that pavement rehab techniques exist today to strengthen and harden the airfield pavement system, making it more resilient and thus less susceptible to flood water inundation damage. Pavement rehabilitation strategies such as full-depth reclamation (FDR) and concrete overlays are being used more frequently to ensure pavements can withstand adverse climatic conditions. Several case studies will be shared and updates on research will be provided.


A Novel Approach for Quantifying Resilience and Concepts of Resiliency in Design and Construction for Concrete Pavements

Presented By: Mi-Geum Chorzepa
Affiliation: University of Georgia
Description: This presentation provides a vision for a large-scale vulnerability and resilience analysis of concrete pavements on both the network and the project levels, as well as concepts for including resiliency in pavement design and construction. The framework is capable of addressing pavement resilience due to natural disasters from climate change including flooding and inundation. The information presented may encourage more discussions and actions by State DOT engineers, consultants, and the concrete industry on how best to plan, design, construct and restore concrete roadways for resiliency in vulnerable area to resist, adapt and recover from impacts of disasters caused by climate change, and achieve longer-lasting, durable concrete pavements.
