ARCHIVAL DATABASE SPECIFICATIONS FOR THE SHRP ASPHALT RESEARCH PROGRAM (REVISED APRIL 1991)

The Archival Database has been designed to serve as the historical record of data that are being generated as part of the Strategic Highway Research Program (SHRP) Asphalt Research Program. The Archival Database will contain individual test results, data sufficient to describe the individual test results, and the conditions under which the results were obtained. Data contained in the Archival Database are the basis for the Summary Database, which will contain summary statistics. The raw, unreduced data will be retained by the researchers as part of their laboratory notebook, computer data acquisition files, or plotter output. The primary puspose of the Archival Database to to provide SHRP researchers with an orderly and well-documented record of the results obtained in the SHRP Asphalt Research Program. When the project is completed, the Archival Database will provide future researchers with a valuable database that can be used for future studies and as a base for continuing the current Asphalt Research Program. The Archival Database is organized as a series of ASCII flat files, each of which contains the individual test results from a single experiment. In contrast, the Summary Database is organized as one large file that can be queried to retrieve test results for different asphalt-aggregate-modifier combinations. For both databases, a user-friendly interface will be provided so that the user can readily retrieve the desired data or files. This document describes the Archival Database.
