Code Section 307.46(2) - Use of Reversion Report

Pursuant to Iowa Code Section 307.46(2), I submit the following report on the use of reversions. The Iowa Department of Transportation spent $498,703 of the Fiscal Year 2010 Road Use Tax Fund/Primary Road Fund budget reversion in Fiscal Year 2011 for desktop, server and network software, information technology professional services and computer equipment.

Use of Reversions, 2013

The Iowa Department of Transportation spent $344,521 of the Fiscal Year 2013 RUTF/PRF budget reversion in FY 2013 for desktop and server software, information technology professional services and computer equipment.

Experimental Use of Calcium Magnesium Acetate, HR-253, 1983

The Iowa Department of Transportation Materials Laboratory personnel announced in early 1982 a process to produce a road deicer consisting of sand grains coated with calcium magnesium acetate (CMA). From that point forward the Iowa DOT began searching for a means of economically producing CMA to their concept. During 1983 and 1984 the first attempts devised for commercially producing CMA were attempted by the W.G. Block Company, Davenport, Iowa, under Iowa Highway Research Board Project HR-253. This first attempt at commercially producing CMA was accomplished by the use of concrete transit mixer equipment. Even though this procedure proved successful in the batch mixing of CMA, the need for higher production rates to reduce the cost per ton still existed. During the fall of 1984, Cedarapids Inc, Cedar Rapids, Iowa, proposed to Iowa DOT personnel the application of their technology to a continuous mixing concept for CMA. Arrangements were made for the continuous test mixing of 60 to 100 tons of CMA/sand deicer. This report covers the production effort, description and results of procedures outlined in Cedarapids Inc's proposal of September 19, 1984. The objectives of this research were: 1. To produce the CMA/sand deicer concept on a continuous mixing basis to Iowa DOT CMA concentration levels. 2. To evaluate the results of preheating the carrying vehicle (sand) prior to CMA ingredient introduction. 3. To analyze the feasibility of production equipment and procedures necessary for portable and/or stationary applications of continuous mixing concepts.

Use of Reversions, Iowa Department of Transportation, 2014

The Iowa Department of Transportation spent $406,240 of the Fiscal year 2013 RUTF/PRF budget reversion in FY 2014 for desktop and server software, information technology professional services, training and computer equipment.

Use of Reversions, 2015 report

The Iowa Department of Transportation spent $488,103 of the FY 2014 RUTF/PRF budget reversion in FY 2015 for desktop consumables, information technology professional services, training and computer equipment.

Use of Remote Sensing for Collection of Data Elements for Linear Referencing Systems, 2001

This report evaluates the use of remotely sensed images in implementing the Iowa DOT LRS that is currently in the stages of system architecture. The Iowa Department of Transportation is investing a significant amount of time and resources into creation of a linear referencing system (LRS). A significant portion of the effort in implementing the system will be creation of a datum, which includes geographically locating anchor points and then measuring anchor section distances between those anchor points. Currently, system architecture and evaluation of different data collection methods to establish the LRS datum is being performed for the DOT by an outside consulting team.
