Select Testing to Screen Materials for Specification Compliance
William Cross, SDSM&T
1/1/1900 - 1/1/1900
1 Define laboratory and field procedures suitable for analyzing, discriminating whether given materials (i.e. vinsol resin AEA's, polysulfide epoxies) meet specification requirements and allowing acceptance screening.
2 Develop approved product lists for certain materials based on the results of these protocols.
1 Review current literature with respect to suitable chemical analysis procedures for materials selected for specification verification.
2 Meet with the technical panel to review project scope and work plan.
3 Acquire samples of materials from both manufacturers and construction projects for both test development and compliance screening.
4 Develop and refine appropriate testing protocols for each material class identified capable of clearly discriminating whether, based on composition and performance testing, a material meets the specification requirements. This approach should be based on component manufacturer's samples, where obtainable, or, if necessary, marked departure of certain products from other, compliant materials.
5 Screen all products currently on the Approved Products List for a given class of materials (i.e. AEA's).
6 Formulate recommendations for each materials class with regard to whether a given product should be retained on the Approved Products List or removed due to noncompliance.
7 Provide a clear rationale for each testing protocol developed, its ability to discriminate between suitable and unsuitable materials and the scientific basis for rejecting noncompliant materials.
8 Provide a plan for screening any new materials in the categories being examined with the requirement that samples submitted for acceptance will be considered based on a manufacturer's obtaining independent laboratory test results using the appropriate protocol.
9 Prepare a final report and executive summary of the research methodology, findings, conclusions, and recommendations.
10 Make an executive presentation to the SDDOT Research Review Board at the conclusion of the project.
