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.

Instrumentation of the Way-30 Test Pavements.

Abstract	The US Route 30 bypass of Wooster, Ohio, in Wayne County, 'WAY-30,'4 was constructed to demonstrate two types of extended service pavements, a long-life Portland cement concrete (PCC) pavement on the eastbound lanes and an asphalt concrete (AC) perpetual pavement on the westbound lanes. Both pavements are designed to provide 50 years or more of service with minimal maintenance (e.g. resurfacing). The PCC pavement structure features a thick and extra-wide slab on an asphalt treated base, while the AC pavement structure features a Superpave surface and a Fatigue Resistant Layer (FRI). Two sections in each direction were instrumented with pressure cells to monitor subgrade pressures and deep and shallow LVDTs to record pavement deflections. The AC test section also had transverse and longitudinal strain gages. A weather station was also used to monitor environmental conditions. Nondestructive testing of the subgrade was conducted prior to pavement placement. Pavement materials and samples were tested in the laboratory to determine material parameters. Controlled vehicle load and falling weight deflectometer tests were applied to the AC pavement shortly after the road opened to traffic in December 2005 and again under hot weather conditions in July 2006. Similar tests on the PCC pavement were conducted in December 2005 and August 2006. The response on both types of pavement met their respective design criteria.
