100 Years of Concrete Pavements in Iowa Final Report, March 2009

Portland cement concrete (PCC) pavements have given excellent service history for Iowa. The first concrete pavement was placed in Le Mars in 1904 and was in service until 1968. The Eddyville Cemetery Road placed in 1909 is still in service today. Many other pavements placed during the 1920s and 1930s are still in service today. The objective of this report is to document various changes in specifications, pavement design and equipment for PCC paving from the early 1900s to present. This includes changes that were made to the specification book and supplemental specifications. Where possible, information is given as a basis for the change in specifications.

FY10 Recycled Content Plastic Bag and Soy Inks Report

As required by Iowa Code section 37.21, the following is a summary of purchasing activities for soy-based inks and recycled content plastic trash bags. The figures are for Fiscal Year 2010. The department currently has no equipment which will operate with soy ink. Iowa Code section 8A.315 required that a minimum of 50 percent of garbage can liner purchases shall be recycled content plastic garbage can liners. The department purchased $51.478.04 worth of recycled content plastic garbage can liners. The represents 93.9 percent of garbage can liners purchased.

Evaluation of PCC Long-Term Durability Using Intermediate Sized Gravels to Optimize Mix Gradations, April 2010

With the implementation of the 2000 Q-MC specification, an incentive is provided to produce an optimized gradation to improve placement characteristics. Also, specifications for slip-formed barrier rail have changed to require an optimized gradation. Generally, these optimized gradations have been achieved by blending an intermediate aggregate with the coarse and fine aggregate. The demand for this intermediate aggregate has been satisfied by using crushed limestone chips developed from the crushing of the parent concrete stone. The availability, cost, and physical limitations of crushed limestone chips can be a concern. A viable option in addressing these concerns is the use of gravel as the intermediate aggregate. Unfortunately, gravels of Class 3I durability are limited to a small geographic area in Mississippi river sands north of the Rock River. Class 3 or Class 2 durability gravels are more widely available across the state. The durability classification of gravels is based on the amount and quality of the carbonate fraction of the material. At present, no service histories or research exists to assess the impact of using Class 3 or 2 durability gravels would have on the long-term durability of Portland cement concrete (PCC) pavement requiring Class 3I aggregate.
