Project Location: Austin, Texas
Client: Environmental Science & Engineering, Austin, Texas
Dates: February 2001

The City of Austin is adding a left-turn lane from northbound Lamar Blvd. to 24th Street. The client contracted LCR&A to provide engineering services related to the geotechnical investigation at this site. LCR&A was also contracted to provide an engineering report of the geotechnical investigation that includes recommendations for the design of the new pavement and a small retaining wall.

The geotechnical investigation followed ASTM standards for soil sampling and laboratory testing. Recommendations for pavement were based on the City of Austin's Flexible Pavement Design System that takes into account traffic volumes, serviceability, maintenance, construction cost as well as other engineering constraints. Studies were made regarding the type of retaining wall and soil stability at the site.
