Book Description
The results of a study undertaken to evaluate premixed polymer concrete overlays (PMPCO) over a 3-year period are presented. The PMPCO evaluated were constructed with polyester amide para resin and silica sand 1;. polyester styrene resin 1 and silica sand 2; polyester styrene resin 2, basalt aggregate and coke breeze (for conductivity); polyester styrene resin 2, silica sand 3 and coke breeze; and vinyl ester styrene resin, silica sand 2, and coke breeze. The mixing of the ingredients was done with either portable concrete mixers, mortar mixers, or a continuous batching mobile concrete mixer. The overlays were struck off and consolidated with a vibrating screed or a slip form paver. The report indicates that a nonconductive PMPCO with high bond strength, low permeability, and high skid resistance can be successfully installed by a contractor and opened to traffic after only three hours of curing. The report indicates that a conductive PMPCO with high bond strength and skid resistance can be successfully installed as a secondary anode for a cathodic protection system. Also, it is shown that the special provision for a PMPCO should require the installation of test patches or test sections of overlay prior to placing the final overlay to assure that the surface preparation is adequate and the mixing, installation equipment, procedures, and materials will provide a satisfactory overlay.

Book Description
The development of a built up, electrically conductive polymer concrete overlay and a premixed, electrically conductive polymer concrete mortar for use on bridge decks and other concrete members, in conjunction with cathodic protection systems, is reported. The research program was divided into two phases. The emphasis of the work performed in phase one was directed towards the evaluation of the 18 commercially available resin systems and the 16 conductive filler systems selected for consideration. Basic studies were also performed to evaluate various parameters affecting the electrical resistivity properties of both the built up overlay and premixed mortar systems. In phase two, extensive evaluation of the physical and mechanical properties of the most promising overlay and premixed mortar systems were performed. In addition, the performance characteristics of the selected overlay systems, when incorporated into active cathodic protection systems, were evaluated.

Book Description
This report describes work done on various combinations of monomers and polymer concrete mixes and identifies the mixes showing the greatest potential for use in bridge deck overlays. Presented are test results showing physical properties of various polymer concrete mixes, such as compressive strength, split tensile strength, modulus of elasticity, thermal coefficient of expansion, and shrinkage coefficient. The effects of polymer content, work time, and temperature on various properties are also discussed. The development of two polymer concrete systems with excellent membrane potential are described along with the details of bonding characteristics of several systems. Finally, a polymer concrete mix with suitable properties for deck and pavement patching is detailed.

Book Description
A dozen papers from a June 1992 symposium in Louisville, Kentucky review the current use of organic polymers dispersed in water and formulated to add to portland cement. One sets out the status of ASTM's forthcoming specification and test methods. Others discuss such aspects as solid grade acrylic c

Book Description
The objectives of this work were to document the state-of-the-practice with respect to polymer concrete overlays, document the placement of two overlays in Iowa, monitor the field performance of the overlays over a two-year period, and relate their performance to material usage and/or workmanship. The two bridges - a Johnson County, Iowa bridge over I-80 on 12th Avenue in Coralville, and the Keg Creek Bridge on Hwy 6 in western Iowa, 10 miles east of Council Bluffs - were overlaid during the summer/fall of 2013. The process by which each bridge was overlaid was similar in many ways, although a few slight differences existed. Over time, each overlay has generally performed quite well with only a few areas of exception. It is believed that these localized areas likely underperformed due to poor deck preparation, improper polymer mixing, snowplow impact, or a combination thereof.
