Recyclability Evaluation of Asphalt Millings with Geosynthetic Interlayer Remnants for Pavement Base Course Applications
The incorporation of geosynthetic interlayers, such as geotextiles and geogrids, in asphalt layers has been shown to delay crack propagation and increase the fatigue life of asphalt overlays. Consequently, the growing use of geosynthetic interlayers in asphalt layers is expected to generate increasing quantities of reclaimed asphalt pavement (RAP) containing geosynthetic interlayer remnants (referred to […]
From Demolition Waste to FAA-Compliant Base Course: Materials Management at DFW Airport
Large airport capital programs generate substantial volumes of demolition debris and surplus excavation material, creating ongoing challenges related to disposal costs, material procurement, hauling logistics, and schedule risk. At Dallas Fort Worth International Airport (DFW), the scale and pace of concurrent airfield and landside construction required a more coordinated, program-level approach to managing construction materials. […]
From Vision to Reality: Delivering Multimodal Projects Through Integrated Planning and Engineering: Connecting Statewide Strategy, Project Portfolio Development, and District Delivery to Advance Transportation Solutions
Moderator: Ram Maddali As transportation agencies work to address growing mobility needs, infrastructure demands, system resiliency, and funding constraints, successful project delivery requires strong coordination between planning, programming, engineering, and implementation. Transforming long-range transportation goals into projects that can be funded, developed, and delivered demands an integrated approach that bridges organizational, technical, and geographic boundaries. […]
Cracks Happen: Designing Better Concrete Pavements with Fibers
Cracking in concrete is inevitable—but poor pavement performance does not have to be. Fiber-reinforced concrete (FRC) provides engineers with an opportunity to rethink how concrete pavements are designed by moving beyond traditional approaches to crack control and reinforcement. This presentation explores the role of fibers in improving the performance, durability, and resiliency of concrete pavement […]
From Insight to Investment: Using Data to Drive Resilient Transportation Decisions: Bridging Data, Policy, and Planning to Guide Transportation Investment Decisions
Moderator: Ram Maddali As transportation needs continue to evolve, agencies must make investment decision to make investment decisions that balance mobility, safety, resilience, environmental stewardship, and fiscal responsibility. At the same time, the volume of available transportation data – from traffic and freight movement to land-use trends, travel demand, and asset condition-continues to expand. The […]
Assessing Roadway Flood Risk with Crowdsourcing and AI
Floods can disrupt urban road networks by slowing down traffic, forcing reroutes, changing daily travel routines, and loss of life. This study uses crowd-sourced data, INRIX traffic data, and hydrologic information and AI models from Houston, Texas, to identify significant risk of flooding. The goal is to uncover hidden travel patterns, assess rerouting behavior, and […]
New Hot Mix Asphalt (HMA) Pavement Specification for Local Agencies, Engineers and Developers
The newly released dense graded Hot Mix Asphalt (HMA) Specification 341M is a streamlined version of TxDOT’s 341 specification from the 2024 TxDOT Spec Book and has been developed specifically for cities, counties and consulting firms doing designs for agencies and developers. This specification has been achieved in collaboration with the Texas Asphalt Pavement Association […]
