This report documents the construction and performance of the Colorado Department of Transportation's (CDOT's) first two Stone Mastic Asphalt (SMA) projects. The first project, located on SH 119 from SH 52 to Longmont, contained three SMA mixes, two polymer-stabilized mixes and one fiber mix. This project successfully demonstrated the design, production and placement of SMA. The second project located on the Colfax Viaduct in Denver was CDOT's first attempt to use SMA on a bridge deck. This project used a polymer-stabilized mix. This project successfully demonstrated the placement of SMA on a bridge deck. SMA is currently being used as a wearing surface in Colorado. Guidelines and a best practice guide have been developed and have been adopted for statewide use. In addition, CDOT's Bridge Branch has developed a specification for using SMA as part of the overlay system.

Corrosion of reinforced concrete structures has been a significant problem for many state and transportation agencies since the application of deicing salts was introduced. Much research has been conducted to develop corrosion protection systems that can prolong the life span of reinforced concrete structures. The Colorado Department of Transportation (CDOT) has several routine and experimental measures to prevent corrosion of the rebar including epoxy-coated rebar, calcium nitrite admixture, organic corrosion inhibitors, a thick cover of quality concrete, and a waterproofing membrane covered by an asphalt overlay. An extensive literature review was performed to collect information on various corrosion protection systems that have been used in the U.S. and around the world. Current CDOT practices in terms of corrosion protection measures were reviewed. A draft inspection plan for Colorado's bridge structures was proposed.

The purpose of this project was to research long-range (parametric) cost estimation at the Colorado Department of Transportation (CDOT), utilizing AASHTO's Trns.port Cost Estimation and Decision Support software. Info Tech, Inc., analysis reviewed CDOT's current long-range estimation practices and identified revisions which would be needed to satisfactorily meet CDOT's future cost estimating requirements, i.e., in order to develop consistent and reliable cost estimates when little is known about a project. Both item and contract classifications utilized by CDOT in BAMS/DSS were revised to reflect more logical functional groupings. The new contract work type and item classification were used directly to develop an Interim Solution for Long-Range Cost Estimation that uses historical bid-based default prices. Info Tech analysts also researched Internet sources to identify the availability of major item cost data at the regional and national level, including data for multimodal project types.

In 1995, the Colorado Department of Transportation implemented the Superpave gyratory mix design to select the optimum asphalt content of a mixture. The optimum asphalt content was not the same as what the department had historically used. The purpose of this study was to gather data to validate the number of gyrations that should be used with the Superpave mix design. Based on the data gathered from the 25 evaluation sections, the optimal number of design gyrations for the Field Mixed/Lab Compacted material is too high. Mixes appear to be too stiff for the traffic and environmental conditions.
