Life-Cycle Cost Analysis

Research in life-cycle cost analysis (LCCA) examines the total cost of ownership for infrastructure assets over their entire lifespan. This field investigates methods for predicting and quantifying expenses associated with initial construction, maintenance, rehabilitation, and eventual disposal. Studies employ probabilistic and deterministic models to assess the economic viability of different design choices, materials, and management strategies. Key areas include the development of advanced pavement design models, analysis of material performance under various conditions, and the integration of uncertainty into cost estimations to inform long-term investment decisions.

This work is particularly relevant to Arkansas's transportation infrastructure, which is vital for the state's economy, supporting agriculture, manufacturing, and logistics. Understanding the long-term costs of building and maintaining roads, bridges, and other public works helps optimize public spending and ensures the resilience of the state's transportation network against environmental factors and heavy usage. LCCA can inform policies related to infrastructure investment, resource allocation, and the selection of sustainable materials, contributing to the efficient development and upkeep of the state's built environment.

This research area intersects with flexible and rigid pavement design, asphalt mixture design, and pavement performance analysis. It also draws upon expertise in materials science and binder performance. Engagement extends across institutions within Arkansas, fostering a collaborative environment for addressing complex infrastructure challenges.
