PROJECT PROCEDURES GUIDE (PPG)

The Bureau of Materials and Physical Research's Project Procedures Guide (PPG) is used as a resource for determining reasonable inspection procedures and sampling frequencies for materials used in highway construction. This Manual seeks to establish materials sampling and testing uniformity throughout the state by providing sampling schedules which list the minimum frequencies at which samples and measurements shall be taken by project, plant, and District personnel.

This Manual applies to all projects constructed on the State system and all Local Agency improvement projects with federal, state, or MFT funds. Specific exceptions to this Manual for Local Agency work are indicated in the current Local Roads and Streets Manual(s) or by circular letter.

Project Procedures Guide (619k) effective 06/01/09
