NTL Classification:NTL-SAFETY AND SECURITY-SAFETY AND SECURITY ; NTL-HIGHWAY/ROAD TRANSPORTATION-Construction and Maintenance ;Format:Subject/TRT Terms:Abstract:Over the past two decades the role of SHA has shifted from quality control (QC) of materials and
placement techniques to quality assurance (QA) and acceptance. The role of the Office of Materials
Technology (OMT) has been shifting towards assurance of material quality and oversight of contractor
quality control operations.
Since SHA deals with a variety of materials and construction processes there is a wide spectrum of
specifications and acceptance requirements. It was the objective of this study to identify typical material
QC/QA procedures and a) examine their conformance in relation to the federal requirements for defining
QA plans, Independent Assurance (IA) procedures, and material certification; b) identify potential
improvements to existing SHA QA plans, when necessary; c) assess product variability based on
production QC data, when available; and iv) evaluate risks related to material acceptance data when
applicable (i.e., when acceptance data are available). To address these objectives the research team had
several meetings with SHA engineers from the (1) Soils and Aggregates Division, (2) Concrete Technology
Division, and (3) Structural Materials and Coatings Division in order to identify the type of materials to
include in the study, and fine tune the specific steps of the research approach to follow.
