Book Description
The purpose of this study is to evaluate the application of FLEXOGRID, a modified epoxy resin, to a concrete bridge deck. The FLEXOGRID is designed to impart a thin, fast curing, water impermeable protective overlay to the deck. The FLEXOGRID is 1/4 inch thick consisting of 2 applications of an epoxy broadcasted with a hard aggregate. The FLEXOGRID was easy to apply after the bridge deck delaminations were repaired and the entire deck was shotblasted. Only minor application problems occurred which can be corrected for future applications.

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
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.
