AI-Powered Infrastructure: Building a More Resilient and Sustainable Future
From predicting the formation of potholes to engineering more durable concrete, artificial intelligence is rapidly transforming the landscape of infrastructure development and maintenance. Researchers are increasingly turning to AI and machine learning to address long-standing challenges related to cost, efficiency, and sustainability. This shift promises not only to extend the lifespan of critical infrastructure like roads and bridges but also to reduce environmental impact and improve disaster preparedness. The application of these technologies represents a significant step towards a more resilient and cost-effective future for construction and civil engineering.
At the University of Mississippi, Dr. Ali Behnood, an assistant professor in the Department of Civil Engineering, is at the forefront of this research. His work, spanning over a decade, focuses on leveraging AI to optimize material selection, predict infrastructure failure, and ultimately create a more sustainable built environment. Dr. Behnood leads the NextGen Infrastructure Lab, dedicated to advancing the next generation of sustainable and resilient infrastructure solutions. He has authored or co-authored more than 60 published research articles in this field, demonstrating a sustained commitment to innovation in infrastructure technology. His expertise has been recognized through inclusion in the Clarivate™ list of Highly Cited Researchers™ and as a ScholarGPS Highly Ranked Scholar, placing him among the top 2% of scientists globally.
Predicting Pavement Failure with Artificial Intelligence
A recent study led by Dr. Behnood, in collaboration with doctoral student Abolfazl Afshin, investigated the use of AI algorithms to predict moisture damage in asphalt pavements. Moisture intrusion is a major contributor to pavement deterioration, particularly in regions experiencing wet and cold climates, leading to issues like stripping, potholes, and cracking. The research team evaluated the effectiveness of four different AI algorithms in predicting this damage in asphalt mixtures containing reclaimed asphalt pavement (RAP) materials.
“We focused on moisture damage, which is one of the most critical issues in asphalt pavements, particularly for wet and cold regions, because it results in a variety of distresses like stripping, potholes and cracking,” Afshin explained. The findings revealed that these algorithms could accurately predict moisture damage, enabling engineers to optimize material selection and forecast the probability of pavement failure throughout its lifecycle. This predictive capability is crucial for proactive maintenance and cost savings.
The economic implications of this research are substantial. According to data from 2021, state and local governments spent over $206 billion on road maintenance. In 2023, the Department of Transportation reported a backlog of nearly $1 trillion in needed repairs and maintenance for roads and bridges. Optimizing asphalt mixtures through AI-driven predictions could significantly reduce these costs and extend the service life of roadways.
Dr. Behnood emphasizes that determining the optimal blend of RAP and other materials to withstand harsh weather conditions would be exceptionally time-consuming and expensive without the aid of AI. “Artificial intelligence-based algorithms offer a cost-effective and efficient alternative to traditional, time-consuming, and energy-intensive lab-based approaches,” he stated. The procedures developed by his team are readily available for use by practicing engineers, transportation departments, federal agencies, and private sector companies seeking sustainable and cost-effective infrastructure solutions.
Beyond Pavements: AI’s Broad Applications in Infrastructure
The potential of AI extends far beyond pavement management. Dr. Behnood highlights numerous other applications within the broader infrastructure sector. These include designing more efficient bridges and roads, optimizing waste management systems, and monitoring railroads for potential faults or breakages. AI’s ability to analyze vast datasets and identify patterns makes it an invaluable tool for preventative maintenance and risk assessment.
AI plays a critical role in enhancing disaster resilience and risk management. In the event of natural disasters or other emergencies, efficient evacuation is paramount. AI algorithms can identify optimized evacuation routes tailored to specific scenarios, ensuring both safety and efficiency. “AI can also play a crucial role in disaster resilience and risk management,” Dr. Behnood explained. “In the event of disasters or natural hazards, evacuation becomes critical, and AI can identify optimized routes tailored to various evacuation scenarios, ensuring efficiency and safety.”
The core goal of Dr. Behnood’s research, as articulated through the NextGen Infrastructure Lab, is to move towards a new era of sustainable and resilient infrastructure. This involves optimizing the use of recycled materials, industrial by-products, renewable resources, and alternative sustainable materials in construction. The team aims to minimize not only the physical costs of infrastructure projects but also associated labor costs, energy consumption, environmental impact, and long-term maintenance expenses.

The Role of Recycled Materials and Sustainable Practices
A key component of Dr. Behnood’s work is the exploration of sustainable materials. The construction industry is a significant consumer of resources and a major contributor to greenhouse gas emissions. By incorporating recycled materials and industrial by-products into infrastructure projects, the environmental footprint can be substantially reduced. This approach aligns with growing global efforts to promote circular economy principles and reduce reliance on virgin materials.
Dr. Behnood’s research extends to evaluating the performance of these alternative materials, ensuring they meet the required standards for durability and safety. AI algorithms are instrumental in analyzing the complex interactions between different materials and predicting their long-term behavior under various environmental conditions. This data-driven approach allows engineers to craft informed decisions about material selection and design, leading to more sustainable and resilient infrastructure.
Dr. Ali Behnood is an Assistant Professor of Civil Engineering at the University of Mississippi, with a Ph.D. From Purdue University. His profile on the University of Mississippi website provides further details on his research and contact information. He is also active in professional organizations such as the American Society of Civil Engineers, the Academy of Pavement Science and Engineering, and the Transportation Research Board, contributing to the advancement of knowledge and best practices in the field.
The widespread adoption of AI-driven solutions in infrastructure development is not without its challenges. Data availability, algorithm transparency, and the need for skilled professionals are all important considerations. However, the potential benefits – reduced costs, improved sustainability, and enhanced resilience – are compelling. As AI technology continues to evolve, its role in shaping the future of infrastructure will only become more prominent.
Looking ahead, Dr. Behnood and his team plan to continue exploring new applications of AI in infrastructure, focusing on areas such as bridge health monitoring, smart city technologies, and predictive maintenance for critical infrastructure assets. The ongoing research promises to deliver innovative solutions that address the pressing challenges facing the infrastructure sector and contribute to a more sustainable and resilient future.
The next step in this research involves expanding the scope of AI applications to include real-time monitoring of infrastructure performance using sensor data and machine learning algorithms. This will enable proactive identification of potential problems and facilitate timely interventions, further extending the lifespan of infrastructure assets and reducing maintenance costs.
