Presentation Evolutionary Characteristics of Microstructural Hydration and Chloride Diffusion in UHPC This webinar presents the evolutionary characteristics of microstructural hydration and chloride migration in ultra-high performance concrete (UHPC). The physicochemical interactions of constituents are simulated in conjunction with a random walk algorithm. The computed responses of the UHPC mixtures at a compressive strength varying from […]

Presentation Developing Enhanced Performance Curves of ITD Asphalt Pavements by Mining the Historical Data This presentation introduces work of a recently finished project aiming to develop reliable and realistic and enhanced performance curves for Idaho Transportation Department (ITD) asphalt pavements by mining the historical data. To this end, the project reviewed currently applied predictive models […]

Presentation Decryption of Concrete Durability Deterioration Mechanisms Using Concrete Petrography and Image Analysis While good workability and mechanical performance are critical for the construction of transportation infrastructure, the stakeholders also seek durable concrete that can last a desired service life without significant deterioration. Concrete durability comes in different forms of complex processes that commonly involve […]
