Hurricane Harvey is considered the worst natural disaster in the history of Texas. Harvey brought one of the most intense rainfall recorded in continental United States. In a four-day period, many areas received more than 40 inches (1,000 mm) of rain as the system meandered over eastern Texas and adjacent waters, causing catastrophic flooding. Hence, the objective of this project is to evaluate the damage caused by Hurricane Harvey to road structures in the SE Texas and SW Louisiana by comparing the strength of pavement structures before and after the hurricane, as reflected by material properties and surface deflections. The damage evaluation will provide a quantitative estimate of the increased maintenance and rehabilitation costs for pavement structures in the regions, and will indicate the pavement structural configurations and material most affected by flooding. This will help highway, county, city and airport authorities in flood prone areas in their process of estimating maintenance and rehabilitation costs and of planning and designing a more resilient infrastructure. |
