Laboratory and test-site testing of moisture-cured urethanes on steel in salt-rich environment / by Chong, Shuang-Ling.(CARDINAL)314375; Romero, Pedro.(CARDINAL)286919; Yao, Yuan,1961-(CARDINAL)319533; Soil and Land Use Technology, Inc.(CARDINAL)319534;
Includes bibliographical references (pages 27-28).Final report;Three 3-coat moisture-cured (MC) urethane commercial products formulated for protecting new steel (SSPC-SP 10) and power tool-cleaned steel (SSPC-SP 3) surfaces against corrosion were evaluated; the total coating film thickness was about 75 microns. Zinc-rich MC-urethane primers were used for SSPC-SP IO steel surfaces whereas the primers for SSPC-SP 3 surfaces contained zero or a small amount of zinc: the same midcoats and topcoats were used for both steel surfaces. Sealers with film thickness of 25 microns were also studied for any potential effect on coating performance of the coating systems for power tool-cleaned surface. The volatile-organic-compound content of all the coating materials was below 340 g/L. The Federal Highway Administration (FHWA)-developed cyclic testing method was conducted to compare the performance of these coating systems. The test included freeze, ultra-violet light/condensation, and salt-fog/dry-air cycles. An aggressive outdoor marine exposure at Sea Isle City, New Jersey, was also performed for all the coating systems for comparison. A number of physical and chemical properties of the MC-urethanes were examined to study their effect on coating performance. All of the coating systems maintained their total film thickness, topcoat hardness, and adhesion strength throughout the 4,000-h test period. The three commercial products were found to contain different chemical compositions and performed differently. All the coating systems had an adhesion strength about 10.5 MPa. No surface failures were observed on any of the test panels after the 4,000-h laboratory test; however, all of them developed creepages at an intentional scribe (undercutting). The laboratory test results in conjunction with the chemical analysis results suggested that pigment particle size distribution in the primers played a more important role than other factors in the formation of creepage at the scribe. A proper pigment particle gradation improved the coating performance. A chloride concentration of 20 micrograms per square of centimeter on the steel surfaces was found to be significant to reduce the coating performance at the scribe of SSPC-SP 10 steel surfaces; however, the chloride effect was found to be minimal for SSPC-SP 3 steel surfaces. Interestingly, all the scribe creepages increased linearly with the laboratory test time up to 4,000 h. Furthermore, the addition of a sealer to the primer/midcoat/topcoat systems unexpectedly impaired the performance at the scribe on SSPC-SP 3 steel surfaces when compared with those systems without a sealer. On the other hand, a coating system with sealer/primer/topcoat without a midcoat developed severe underfilm corrosion probably due to insufficient film thickness.Sponsored and performed by Office of Infrastructure RD & T.

Evaluation of urethane snow plow blades as an alternative to rubber blades / by Roosevelt, Daniel S.(CARDINAL)313786; United States.Federal Highway Administration.(CARDINAL)139839; Virginia.Department of Transportation.(CARDINAL)291718; Virginia Transportation Research Council.(CARDINAL)195142;
Includes bibliographical references (page 11).Final report;The purpose of this study was to determine if urethane blades are a suitable alternative to rubber blades for use on snow plows. The importance of finding a suitable alternative is due to the anticipated increased need to protect the new, longer lasting, and expensive preformed tape now being introduced as pavement markings in Virginia. Two sites were selected to test urethane blades, and six sites were selected to test rubber blades. The study reviewed the cost and quality of snow removal for each type of blade. The study found that urethane blades cleaned the roadway surface better than rubber blades but were subject to the same problem of low durability. The Virginia Department of Transportation (VDOT) uses a plowing method that places the full weight of the plow on the blade. This method results in high friction between the blade and the road surface, which causes the blades to wear quickly. The rapid disintegration of the blades within a single snow event makes life-cycle cost a moot point. Limited data, however, indicated that the life-cycle cost of urethane blades was 6.5 times greater than that of rubber blades. Many airports extend the blade life of urethane blades on their plows by removing the weight of the plow from the blade through the installation of wheels on the plow. Since the conditions under which VDOT currently uses rubber blades is similar to airport conditions, the study recommends that VDOT plows be modified to take the plow's weight off the blade and that urethane blades be substituted for rubber blades. The study was unable to determine if the use of wheel-supported plows equipped with urethane blades would sharply reduce damage to pavement markings. The study recommends that an additional study be conducted in the coming winter season to determine the effect of properly supported urethane blades on pavement markings and the suitability of urethane blades for snow removal under a wider range of conditions.Performed by the Virginia Transportation Research Council, under project no.

Evaluation of urethane and carbide-tipped blades on wheel-supported snow plows / by Roosevelt, Daniel S.(CARDINAL)313786; Cottrell, Benjamin H.(CARDINAL)311411; Virginia Transportation Research Council.(CARDINAL)195142;
Includes bibliographical references (pages 30-31).Final report.The objective of this study was to evaluate the performance of urethane and carbide-tipped snow plow blades on wheel supported plows. Their performance was compared to that of VDOT's standard blade arrangement: carbide-tipped blades on plows without wheels. Performance was measured by the extent of damage to pavement markings, the quality of snow removal, and cost. The addition of wheel supports to plows with carbide-tipped blades prolonged the retroreflectivity and service life of pavement markings. A life-cycle cost analysis revealed that carbide-tipped blades without wheels were the least expensive alternative, followed closely by carbide-tipped blades with wheels, and then urethane blades with wheels. When compared with carbide-tipped blades without wheels, carbide-tipped or urethane blades with wheels were effective in removing loose, but not packed, snow. Timely chemical application to prevent snow-pavement bonding is crucial, particularly with wheel-supported plows. Urethane blades are susceptible to wear through friction and are impractical for use on second and third priority snow routes where variations in cross slope and soft shoulders bring the blade into contact with the pavement. The use of supports on plows equipped with carbide-tipped blades allows the operator the option to use the plow in a supported mode for first priority routes and an unsupported mode for second and third priority routes. Proper alignment of the wheels is critical to ensure proper operation, protection of the urethane blades from wear, and reduction of damage to pavement markings. Measuring the monetary value of increased and prolonged retroreflectivity of pavement markings and more effective snow removal is difficult. The authors recommend that VDOT not use urethane blades as a replacement for carbide-tipped blades under current operating conditions. However, if VDOT continues to make brighter and more durable pavement markings a high priority, then it should consider using carbide-tipped blades on plows with wheels. Other actions that balance protecting Virginia's pavement marking investment and ensuring effective snow removal, such as restricting the use of heavy equipment for snow removal and providing operator training, should also be considered. Finally if supported plows are adopted for use, other options to support the plow should be investigated through product evaluations by VDOT personnel.Sponsored by Virginia Department of Transportation [and the] Federal Highway Administration, under project no.

Beverly Fishman. by Fishman, Beverly,artist.(CARDINAL)895508; Hart, Rebecca R.,writer of supplementary textual content.(CARDINAL)284830; Miles McEnery Gallery,host institution.(CARDINAL)783869;
A Prescription / by Rebecca Hart -- Plates -- Biography -- Select Collections."Miles McEnery Gallery is delighted to present Something For The Pain, Beverly Fishman's third solo exhibition with the gallery. The exhibition is on view 27 April through 3 June 2023 at 515 West 22nd Street. Accompanying the exhibition is a fully illustrated catalogue featuring an essay by Rebecca Hart. From the outset of a four decade career, Beverly Fishman has centered her work around the body, probing abstract investigations of disease, identity, and medicine. Since 1999, her oeuvre has propelled towards the latter, delving into the promises of pharmaceuticals as the means for a cure. Fishman positions the sculptural paintings in Something For The Pain within the concept of polypharmacy--the prescription of multiple medicines to one individual. Glowing fluorescent and smooth matte forms correspond to specific pills as Fishman expertly illustrates the measured precision of an individual's unique prescription. Geometric fragments are stacked into singular compositions; some segments rendered whole and others fractured to imply partial doses. Parenthetical titles pronounce the works to indicate each ailment meant for treatment. Both welcoming and unsettling, Fishman's consistent use of urethane paint on wood lures viewers toward her floating structures; their edges bevel towards the wall, reflecting the neon-painted undersides and creating an artificial glow that mimics a physical light. Both her innate sensibility for color and the sheer scale of the works demand attention that further provokes an interrogation surrounding Big Pharma and one's relationship to the body and its current environment. "Listening carefully to the world around her, the artist co-opts the language of painting--line, color, form, texture-- and compounds it with the art of medicine--diagnosis, management, and sometimes a cure," writes Rebecca Hart. "A prolific maker, Fishman traces the evolution of medical and pharmacologic discovery, injecting it with personal and cultural content... Aggregating this information as source material for her ongoing exploration, Fishman's paintings are bellwethers of the effects of industrialized medicine."" -- Miles McEnery Gallery website."Beverly Fishman (b. 1955 in Philadelphia, PA) received her Master of Fine Arts in 1980 from Yale University and her Bachelor of Fine Arts from the Philadelphia College of Art in 1977.
