摘要：	Most codes of practice prescribe procedures for selecting patch configuration and materials based on test devised for evaluating new pavement materials. The study is aimed at examining the special consideration to be given to such evaluation procedures and to suggest improved procedures for brittle repair materials, based on additional tests and computer analysis. The first part of the present investigation covers the experimental study, in which three different repair materials, namely plain concrete, steel fiber concrete, and rapid patch material (Duracel cement) are investigated. Tests are conducted on two different patch configurations (transition and rectangular) and three different patch depths (2, 4 and 6 inches). In the second part of the study, a mechanistic patched pavement analysis program is developed to assist in the evaluation of patching procedures and materials. Such a program can be used to develop curves which aid in the selection process. It can also be used for a case by case analysis for specific problems. This program can analyze both intact and patched concrete pavements considering different loading and support conditions, material properties, patch configurations, and depths. The report is present in two volumes. Volume II contains the Appendices. A separate Summary Report is issued as report number FHWA/LA-92/253.
