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 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 (PIC) and polymer concrete (PC), 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.

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.

Available in PDF, EPUB and Kindle. Book excerpt: The practicality of using polymer concrete to repair holes in bridge decks has been demonstrated by the repair of two large holes in the Third and Lincoln Avenues Viaduct of the Major Deegan Expressway in New York City. All of the work was confined to the non-rush hour (10AM-3PM) part of the day and at least one lane of traffic was maintained on the roadway at all times. The material cost of polymer concrete was 1400 dollars or 260 dollars-cu yd. This represented 4% of the total repair cost and indicates that the material cost is insignificant when repairs on major arterial highways are performed. The use of polymer concrete appears cost effective.
