Validation of Gyratory Mix Design in Iowa, TR-667, 2016

The design number of gyrations (Ndesign) introduced by the Strategic Highway Research Program (SHRP) and used in the Superior Performing Asphalt Pavement (Superpave) mix design method has been commonly used in flexible pavement design throughout the US since 1996. Ndesign, also known as the compaction effort, is used to simulate field compaction during construction and has been reported to produce air voids that are unable to reach ultimate pavement density within the initial 2 to 3 years post-construction, potentially having an adverse impact on long-term performance. Other state transportation agencies have conducted studies validating the Ndesign for their specific regions, which resulted in modifications of the gyration effort for the various traffic levels. Validating this relationship for Iowa asphalt mix designs will lead to better correlations between mix design target voids, field voids, and performance. A comprehensive analysis of current Ndesign levels investigated the current levels with existing mixes and pavements and developed initial asphalt mix design recommendations that identify an optimum Ndesign through the use of performance data tests.

In Service to Iowa : Public Library Standards, 6th edition, August 8, 2016

The Standards and Accreditation Program exists to encourage the ongoing development of high quality public library services in Iowa. In Service to Iowa: Public Library Standards is the manual for the State Library of Iowa’s standards program. It was first published in 1985 and was updated in 1989, 1997, 2004, 2010, and now in 2016. Iowa’s voluntary public library standards program was established to give public libraries a tool to identify strengths and areas for improvement. It is also used to document the condition of public library service in Iowa, to distribute Direct State Aid funding, and to meet statutory requirements. In 2015, the Iowa Commission of Libraries appointed the Public Library Standards Advisory Task Force to revise In Service to Iowa. The Task Force in turn solicited feedback from the State Library Advisory Panel to ensure that proposed standards meet the changing needs of Iowa’s public libraries. All task force members support and stress the importance of the accreditation process and thank the Iowa public library community for its assistance.

State of Iowa Cybersecurity Strategy, July 2016

On December 21, 2015, Governor Branstad issued Executive Order 87 (EO87); a cybersecurity initiative for the State of Iowa. The executive order establishes a multi-agency partnership, the EO87 Leadership Team, with the Office of the Chief Information Officer, Iowa National Guard, Department of Public Safety, Iowa Communications Network, and the Iowa Homeland Security and Emergency Management Department. The order directs these agencies to develop a comprehensive cybersecurity strategy which addresses lifeline critical infrastructure, risk assessments, best practices, awareness training, public education and communication, collaboration, K-12 and higher education, data breach notifications, and incident response planning to protect the citizens of Iowa and Iowa businesses. The EO87 Leadership Team, along with several key partners, worked diligently over the last six months to prepare recommendations that will have a direct and sustainable impact on protecting lifeline critical infra-structure, reducing risk to government operations, and creating sustainable partnerships in cybersecurity.
