National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Tensar Geogrid-Reinforced Soil Wall: Grade-Separation Structures on the Tanque Verde-Wrightstown-Pantano Roads Intersection, Tucson, Arizona. Experimental Project 1. Ground Modification Techniques.

PB90258237

Publication Date	1989
Page Count	142
Abstract	The report documents relevant information on the design, construction, and performance of Tensar geogrid-reinforced soil retaining walls used in grade-separation structures on the Tanque Verde-Wrightstown-Pantano Roads Intersection project in Tucson, Arizona. The project represents the first use of geogrid reinforcement in mechanically stabilized earth (MSE) retaining walls in a major transportation-related application in North America. The reinforced soil walls, which were constructed in 1985, have full height concrete facia panels and range up to 21.9 feet in height. Five main topics are discussed in the report: Tensar SR2 geogrid reinforcement; design of the retaining walls including connections between the geogrid and facia panels; construction steps including pretensions of the geogrid layers; and instrumentation, both during and after construction; and performance based on field observations.
