Statistical Methods for WSDOT Pavement and Material Applications


This document is an upgraded version of Research Report WA-RD 143.2 (February 1988) and is principally the result of continuing work on the WSDOT Pavement Management System (WSPMS). Various statistical methods have been used in the WSPMS and the research team wanted to summarize some of these applications in a separate, straightforward report which may be of value to a broader group of users.
