Project Location: Austin, Texas
Client: Environmental Science & Engineering, Austin, Texas
Dates: April 2000

The City of Austin is adding a left-turn lane from eastbound Riverside Dr. to Wickersham Lane and an acceleration lane on westbound Riverside Dr., west of the u-turn from Pleasant Valley Road. The client contracted LCR&A to provide engineering services related to the geotechnical investigation at these sites. LCR&A was also contracted to provide an engineering report of the geotechnical investigation that includes recommendations for the design of the new pavement.

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.
