Records Management System: Indexing Standard, Document Standard, Technology Standard, Laboratory Configuration, 1997

Purpose of Records Management Sysytem indexing standards document is to develop indexing standards that will best support Iowa DOT's effort to build an agency-wide Records Management System

Laboratory performance evaluation of CIR-emulsion and its comparison against CIR-foam test results from Phase III, TR-578

Currently, no standard mix design procedure is available for CIR-emulsion in Iowa. The CIR-foam mix design process developed during the previous phase is applied for CIR-emulsion mixtures with varying emulsified asphalt contents. Dynamic modulus test, dynamic creep test, static creep test and raveling test were conducted to evaluate the short- and long-term performance of CIR-emulsion mixtures at various testing temperatures and loading conditions. A potential benefit of this research is a better understanding of CIR-emulsion material properties in comparison with those of CIR-foam material that would allow for the selection of the most appropriate CIR technology and the type and amount of the optimum stabilization material. Dynamic modulus, flow number and flow time of CIR-emulsion mixtures using CSS-1h were generally higher than those of HFMS-2p. Flow number and flow time of CIR-emulsion using RAP materials from Story County was higher than those from Clayton County. Flow number and flow time of CIR-emulsion with 0.5% emulsified asphalt was higher than CIR-emulsion with 1.0% or 1.5%. Raveling loss of CIR-emulsion with 1.5% emulsified was significantly less than those with 0.5% and 1.0%. Test results in terms of dynamic modulus, flow number, flow time and raveling loss of CIR-foam mixtures are generally better than those of CIR-emulsion mixtures. Given the limited RAP sources used for this study, it is recommended that the CIR-emulsion mix design procedure should be validated against several RAP sources and emulsion types.

CALS brochure and visitor guide (Center for the Advancement of Laboratory Science)

Located in Coralville in the heart of Iowa’s Creative Corridor, the center for the Advancement of Laboratory Science (CALS) is a public venue intended for use by environmental and public health stakeholders, educational groups, and community businesses and organizations with needs for meeting space. This conference and training facility was established in recognition of a need for a space that unites working professionals, students, educators, community business partners and other community members in a cultivating environment dedicated to environmental and public health stewardship. The CALS is located within the State Hygienic Laboratory at the University of Iowa (SHL) and is comprised of a conference center and training laboratory. The Hygienic Laboratory has a rich history as a national leader in public health education and training and through the CALS. The SHL aims to provide training to the current workforce, recruit the workforce of tomorrow and strengthen community engagement
