This Instructional Memorandum formally describes the data collection and summary and documentation of pavement materials and designs and construction events. This historical documentation procedure has been in place on an informal basis dating back to the earliest pavement projects. A sample report form, priority schedule and distribution listing are provided.
The District Materials Engineer will be responsible for initiating the report and for maintaining one file at the District Office. Statewide files will be maintained in the Office of Materials.
Data required is shown as entry items on page 2 of this IM. Entry items may be altered or adjusted to accommodate special conditions and situations.
Information on contract quantities need include only the bid items, which relate directly to pavement performance. Omit such items as erosion control, traffic control etc.
Complete and file history reports prior to March 1 for projects completed the previous construction season.
In case a backlog of projects exists it may be impractical to complete reports for all past work. The more important projects should be complete in accordance with the following priority schedule.
1. Interstate, primary & secondary - current year’s work
2. Interstate - prior years
3. Primary - prior years
4. Secondary - prior years
