This book was released on 1976 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: The development and field evaluation of a technique of impregnating new concrete bridge decks with an acrylic polymer system to a depth of 1 inch (25 mm) or more for protection against chloride induced corrosion of the reinforcing steel and freeze-thaw deterioration is reported. The durability of concrete treated with the polymer impregnation technique was determined in chloride intrusion, freeze-thaw and skid and abrasion resistance tests. The first polymer impregnation of the entire riding surface of a full size bridge deck was performed as a part of this research and development program in October 1974. A detailed discussion of this first field treatment and a general discussion of two subsequent full size bridge treatments which resulted in refinements to the treatment technique are included.

Available in PDF, EPUB and Kindle. Book excerpt: With the continued use of deicing salts coupled with the small amount of cover constructed over the top mat of steel in many bridge decks badly deteriorated concrete bridge decks are becoming an increasing problem. To prevent this in the future on structures being constructed now, some means of positively sealing the surface of the concrete deck against the intrusion of moisture and deicing salts is needed. Linseed oil treatments and asphalt seal coats are not 100% effective and improved methods are needed. Researchers under cooperative research study 3-9-71-114, Concrete-Polymer Materials for Highway Application, developed in the laboratory and field tested a method of "polymer impregnating" concrete bridge decks. This report describes in detail the method of polymer impregnating a new 64'8"x751' bridge deck at Big Spring, Texas. A drying method using gas fired infrared radiant heaters for drying the deck and polymerizing the monomer system was developed by the contractor. This method did not require an insulated enclosure, provided uniform heat on the deck and was considered to be an efficient economical construction method. The impregnation depths achieved were generally the 1/2"--5/8" range.

This book was released on 2011 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 423: Long-Term Performance of Polymer Concrete for Bridge Decks addresses a number of topics related to thin polymer overlays (TPOs). Those topics include previous research, specifications, and procedures on TPOs; performance of TPOs based on field applications; the primary factors that influence TPO performance; current construction guidelines for TPOs related to surface preparation, mixing and placement, consolidation, finishing, and curing; repair procedures; factors that influence the performance of overlays, including life-cycle cost, benefits and costs, bridge deck condition, service life extension, and performance; and successes and failures of TPOs, including reasons for both.

Available in PDF, EPUB and Kindle. Book excerpt: The rapid deterioration of concrete bridge decks as a result of the increased use of deicing salts is one of the most severe problems facing the highway industry today. One possible solution to the problem is the use of concrete polymer materials. The materials of prime interest are polymer-impregnated concrete and polymer concrete, both of which have excellent durability and strength properties. Three potential applications (repair of deteriorated bridge decks, polymer impregnation of new bridge deck surfaces, and full impregnation of precast deck panels) have been studied in laboratory and field tests, and the results have been encouraging. These results and economic considerations are described in the paper. The work in each of the areas is currently being implemented by the Federal Highway Administration.

Available in PDF, EPUB and Kindle. Book excerpt: Research was done in three general areas: material properties of polymer-impregnated concrete, repair of deteriorated and delaminated bridge decks, and polymer impregnation of new deck surfaces. Structural and durability properties of impregnated normal and structural lightweight concretes were measured. Effects of temperature and cyclic loading were investigated and bond pull-out strength of reinforcement was measured. Process variables studied include monomer type, method of polymerization, aggregate type, and air content of the concrete. Compared with the controls, the properties of MMA-impregnated samples were improved by factors ranging from 2.6 to 4.5. Use of polymer-impregnated concrete to prevent chloride penetration into bridge decks was demonstrated and prototype deck panels have been evaluated. Impregnation offers a potential solution to the bridge deck deterioration problem. Impregnated curbstones are also being tested. Techniques for repairing highly deteriorated and delaminated bridge decks by monomer impregnation were demonstrated in field tests in which a 6-in.-thick section of deck was impregnated. Cores taken from the reconstituted deck had compressive strengths and water absorptions of 5000 psi and 1.6 percent, respectively. Plans to repair an entire deck are being formulated by NYSDOT. Low-viscosity monomer systems that can be used to repair delaminated concrete have been developed. (auth).

This book was released on 1975 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: Three 180', simple span, composite plate girder structures were designed to approximate the material requirements and first cost associated with a polymer-impregnated concrete as compared to those for a conventional concrete bridge deck. The structures were designed by the working stress method, and although the AASHTO code was applied where applicable, some assumptions were made in the design of the polymer-impregnated deck. The results indicate that by using polymer-impregnated concrete rather than conventional concrete in a bridge deck, material requirements may be altered as follows, depending upon the assumptions and specifications applied in the design. 1. Deck concrete : 0 to 41% less, 2. Deck reinforcing steel : 0 to 115% more, 3. Structural steel : 0 to 16% less, 4. Substructure : 0 to 17% less. Assuming that polymer-impregnated concrete costs about twice as much as conventional concrete, the structures with a polymer deck cost from 0.5% less to 10.5% more than the structure with a conventional deck. Based on these findings it appears that the material savings that can be achieved by using polymer-impregnated concrete in a bridge deck may tend to offset the high unit cost of the concrete, but not enough to justify its use on a first cost basis. However, performance specifications for concrete polymer materials must be developed before an accurate determination of material savings can be made.
