Description
The advent of solar energy utilization in highway infrastructure around the country has been increasing in recent years. Right of Ways (ROWs) have several advantages for energy development such as the existing electrical infrastructure aligned with the major highways, a secured boundary, and easy maintenance access. To understand the potential impacts on driver safety, environmental resources, and maintenance operations, case studies are presented...

Description
Truncated base mechanically stabilized earth walls are the MSE walls with narrow base excavation length and steep excavation slope designed to save construction cost while pushing the technological envelope of geosynthetic reinforcement development. A wall with truncated geometry of a narrow base length and steep excavation slope can significantly increase its base bearing pressure.

Description
This report documents two efforts to support CDOT in the area of Safety Performance Function (SPF) development. The first involved the data collection and development of SPFs for five categories of ramp terminals at diamond interchanges. The second effort involved estimating the overdispersion parameters for a number of existing SPFs already in use by CDOT for various roadway segment categories.

Description
Proper structural design of pavement systems requires knowing the resilient modulus of the soil as this parameter is a proven predictor of the stress-dependent elastic modulus of soil materials under traffic loading. In addition, the R-value test is conducted using a device called a stabilometer, where the material's resistance to deformation is expressed as a function of the ratio of the transmitted lateral pressure to that of the applied vertical...
