摘要：	This report documents the findings of a forensic investigation to determine the causes of premature failures noted in brick paver crosswalks in the Court Square area in Charlottesville, Virginia. Brick paver crosswalks were installed in late November to early December 2004 and began to show signs of permanent deformation within approximately 18 months after installation. This study sought to examine the cause(s) of this deterioration through a forensic investigation, to provide recommendations for corrective action, and to present suitable designs for long-term performance. The findings are expected to lead to significant cost savings for the City of Charlottesville by eliminating future premature failures and providing alternative designs suitable for moderate- to low-volume urban settings and criteria for evaluating future designs. The findings suggest that minor changes to specifications and construction procedures could greatly increase the service life of brick crosswalk structures used in urban conditions. If an approximate construction cost is $25 per square foot, the construction of four crosswalks within each intersection (assuming two 10-foot travel lanes, two 8-foot parking lanes, and a length of 8 feet) costs nearly $30,000.
