Improving Design and Construction of Transportation Infrastructure through Bedrock Characterization
Tertiary bedrock formations are commonly encountered during the design and construction of transportation infrastructure in Wyoming. The engineering properties of these bedrocks are highly variable due to the geological processes to which they have been subjected including deposition, cementation, weathering and erosion. Furthermore, comprehensive experimental investigations on these bedrocks are rarely performed in the past due to the absence of advanced rock testing equipment, and hence their strength and deformation behaviors are not well understood. However, transportation infrastructure, such as bridges, slopes and roadways, is either constructed on or associated with these bedrock formations in Wyoming. The overall objective of the proposed research is to understand the strength and deformation behaviors of Wyoming bedrocks in order to improve the resilience of Wyoming transportation infrastructure to disaster. The research objectives will be achieved by completing six major tasks: literature review, assessment of Wyoming Department of Transportation (WYDOT) electronic database and rock inventory, geotechnical investigation and rock sampling, laboratory rock testing, data analysis and correlation development, and outcomes recommendations and reporting. The research will yield many beneficial outcomes pertinent to design and construction of transportation infrastructure.
