Laramie Pavement Study

In 2010 DOWL partnered with the City of Laramie to develop an innovative and comprehensive pavement tool in the form of the Laramie Pavement Study. The study included an in-depth investigation component focused on subsurface soil and groundwater conditions, traffic characterizations, and source aggregate analysis. These investigations provided great insight into existing conditions and served as the backbone for the study. Building on the investigation results, the study established pavement section recommendations based on street and soil types. Innovative design tools were used in the study and included a soil zone map and design charts.

In 2016, DOWL was again contracted by the city to develop a second edition to the study. This included a complete review and update of the original study. A majority of the study’s document did not change significantly; however, it did undergo a complete update. Key improvements included were:

• Explanations of specific pavement design parameters
• Enhanced geotextile/geogrid guidance
• Guidance regarding use of recycled materials
• Asphalt Mix Design criteria was updated to include SuperPave mixes
• General guidance regarding rehabilitation
• Construction assistance
• Empirical solution for estimating soil support

The study included an in-depth investigation component focused on subsurface soil and groundwater conditions, traffic characterizations, and source aggregate analysis.
