Pavement Design
Pavement Design - Scope of Services
The Pavement Design Unit plays a crucial role in developing pavement structures across the state’s transportation network, including highways and airports.
This unit is tasked with designing both new pavement sections and restoration projects, utilizing the latest advancements in technology and materials to ensure high-quality, durable roadways.
Our responsibilities encompass designing overlays as part of the Pavement Restoration Program and handling complex interstate rehabilitations and urban systems.
By integrating cutting-edge technology with rigorous analysis and expert coordination, the Pavement Design Unit strives to enhance the resilience and efficiency of the state’s transportation infrastructure.
Pavement Design Key Functions
Advanced Design Modeling
Leveraging specialized software and a deep understanding of Federal Highway Administration (FHWA) and American Association of State Highway and Transportation Officials (AASHTO) criteria to create efficient pavement designs.
Life Cycle Cost Analysis (LCCA)
Evaluating alternative pavement designs to ensure necessary contract information is readily supplied to the Contracts and Specifications Section prior to bidding alternative pavement design projects.
Coordination and Data Analysis
Working closely with laboratory personnel to analyze shallow soil subgrade data essential for pavement design. This includes reviewing soil properties such as Atterberg limits, sieve and hydrometer tests, and water table depth to determine the most effective stabilization techniques, including lime and cement treatment or modification with geosynthetics.
