In performing such winter maintenance, the selection of appropriate ice-control products for the bond prevention task involves consideration of a number of factors, as indicated in Nixon and Williams (2001). The factors are in essence performance measurements of the ice-control products, and as such can be easily incorporated into a specification document to allow for selection of the best ice-control products for a given agency to use in its winter maintenance activities. Once performance measures for de-icing or anti-icing chemicals have been specified, this allows the creation of a quality control program for the acceptance of those chemicals. This study presents a series of performance measurement tests for ice-control products, and discusses the role that they can play in such a quality control program. Some tests are simple and rapid enough that they can be performed on every load of ice-control products received, while for others, a sampling technique must be used. An appropriate sampling technique is presented. Further, each test is categorized as to whether it should be applied to every load of ice-control products or on a sampling basis. The study includes a detailed literature review that considers the performance of ice-control products in three areas: temperature related performance, product consistency, and negative side effects. The negative side effects are further broken down into three areas, namely operational side effects (such as chemical slipperiness), environmental side effects, and infrastructural side effects (such as corrosion of vehicles and damage to concrete.) The review indicated that in the area of side effects the field performance of ice-control products is currently so difficult to model in the laboratory that no particular specification tests can be recommended at this time. A study of the impact of ice-control products on concrete was performed by Professor Wang of Iowa State University as a sub-contract to this study, and has been presented to the Iowa Highway Research Board prior to this report. 530 $a Also available via the Internet. 536 $a Sponsored by the Iowa Highway Research Board $f project TR471 650 0 $a Deicing chemicals $x Evaluation. 650 0 $a Roads $x Evaluation. $x Materials $x Evaluation. 650 0 $a Corrosion and anti-corrosives $x Evaluation. 650 7 $a Deicing chemicals. $2 trt $9 8122 650 7 $a Performance measurements. $2 trt 700 1 $a Nixon, Wilfred A. 710 1 $a Iowa. $b Highway Research Board. 710 2 $a Iowa Institute of Hydraulic Research. 830 0 $a IIHR report ; $v no. 463. $9 44530 856 41 $u http://www.operationsresearch.dot.state.ia.us/reports/reports%5Fpdf/hr%5Fand%5Ftr/reports/tr471.pdf 856 41 $u http://worldcat.org/oclc/191825604/viewonline $3 View online 941 $a 1 952 $l IAOX771 $d 20240710101522.0 956 $a http://locator.silo.lib.ia.us/search.cgi?index_0=id&term_0=C6F3A12A493111E49277FB87DAD10320 994 $a C0 $b IOZInitiate Another SILO Locator Search
