      <title>TESTING OF SOLAR PHOTOVOLTAIC ARRAYS FOR UTILIZATION ON MARINE AIDS TO NAVIGATION</title>
      <link>https://trid.trb.org/View/169090</link>
      <description><![CDATA[In 1978, approximately 400 solar photovoltaic arrays were procured and placed at marine exposure facilities in Groton, Connecticut, and Fort Lauderdale, Florida. The arrays were measured quarterly to ascertain the effects of the marine environment on electrical performance. Concurently, a screening test for photovoltaic arrays to be used in the marine environment was developed at the Coast Guard R and D Center. Identical panels to those on test at the exposure sites were run through the pressure, immersion, and temperature (PIT) screening test. Baed on the marine environment exposure test and the PIT screening test recommendations are made on the constitutent materials and construction techniques of solar photovoltaic arrays that are most suited to use in the marine environment.

      <title>IMPLEMENTATION - PREDICTING MOISTURE INDUCED DAMAGE TO ASPHALT CONCRETE DESIGN MIXES</title>
      <link>https://trid.trb.org/View/177120</link>
      <description><![CDATA[Six aggregate sources from around the State of Montana were selected to represent various qualities of aggregate and asphaltic concrete. Resilient ('R') Modulus tests, maximum tensile split tests and immersion compression tests were performed on each source and compared for correlation. Specimens used for the resilient modulus and the maximum tensile split tests were subjected to severe temperature conditioning, representing several years of natural exposure. The resultant data indicates that the use of the maximum tensile split tests and the 'R' modulus test are not appropriate for use on a routine basis. The Montana Department will continue to use the immersion compression test for moisture susceptibility prediction.]]></description>

      <title>PERSONAL FLOTATION DEVICES RESEARCH. VOLUME 2. RESEARCH REPORT</title>
      <link>https://trid.trb.org/View/75679</link>
      <description><![CDATA[Research on personal flotation devices (PFDs) is reported in three volumes. Volume 1 summarizes the research and presents a Proposed Technical Approach for development of performance-based PFD evaluation procedures. Volume II is the technical report. Volume III contains appendices. The Life-Saving Index (LSI) System provides a quantitative measure of the life-saving capability of PFDs called the Life-Saving Index (LSI). The LSI predicts the life-saving performance of the candidate PFD and makes it possible to compare diverse PFDs including inflatables, hybrids, and inherently buoyant devices. In one of two studies of PFD wearability/accessibility, nearly 2500 boaters were observed in recreational boating activities. In Study II, 67 different kinds of PFDs representing the major varieties available world-wide were distributed to recreational boaters for use and evaluation. Indices of PFD wearability and accessibility were developed, based upon evaluations and PFD use behavior. One approach to PFD effectiveness used the center and distribution of buoyancy to predict the effectiveness of PFDs on human subjects. A second approach employed an anthropomorphic dummy to simulate human buoyancy characteristics. A PFD effectiveness evaluation procedure using human body simulators is recommended. Reliability research centered on the development of an accelerated aging method which simulates the aging of PFDs in the recreational boating environment. Controlled experiments were performed to determine the individual and combined effects of environmental stressors on PFDs. Test procedures and a reliability model are presented.]]></description>

      <title>DEVELOPMENT OF A FRANGIBLE APPROACH LIGHT</title>
      <link>https://trid.trb.org/View/56647</link>
      <description><![CDATA[This document describes the effort expended by Connecticut International Corporation in Fullfillment of Contract DOT-FA-75WA-3610 to develop a lightweight, frangible approach light housing. The program demonstrated that the goal of frangibility was not achievable as initially concepted. However, significant progress has been made in the state of the art relative to housings which are lightweight, suitable for the visual aid purpose intended, and with a substantial measure of frangibility.

      <title>ACCELERATED STRESS TESTING OF SOLAR PHOTOVOLTAIC MODULES</title>
      <link>https://trid.trb.org/View/171636</link>
      <description><![CDATA[In 1974, the U.S. Coast Guard began investigating solar photovoltaic arrays as power sources for marine aids to navigation. Initially, 53 systems consisting of a solar array, battery, and a flashing lamp load were placed in a rooftop test facility adjacent to Long Island Sound in Groton, CT. Within two years, the solar arrays of 25 systems had no power output thereby indicating failure. Effects of the marine environment were judged to be responsible for the failures. In order to use solar arrays on operational aids to navigation, much greater reliability was essential. Consequently, development work was initiated on an accelerated stress test system that would rapidly identify solar photovoltaic modules capable of surviving in the marine environment. This interim report traces the history of accelerated stress testing of solar photovoltaic modules carried out at the U.S. Coast Guard R&D Center. It describes the military standard tests to which the prototype modules were exposed to and the results of that exposure. The report traces the evolution of the simultaneous multiple stress test to the present marine environment screening test. The results of exposure to the marine environment screening test of 136 test modules are reported. (Author)]]></description>

      <title>STANDARD SPECIFICATIONS FOR TRANSPORTATION MATERIALS AND METHODS OF SAMPLING AND TESTING 1997. EIGHTEENTH EDITION. PART II - TESTS</title>
      <link>https://trid.trb.org/View/536745</link>
      <description><![CDATA[This Eighteenth Edition of Transportation Materials is published in two parts.  Part I contains specifications for materials, and this Part II includes methods of testing and specifications for testing equipment.  Part II contains approximately 127 test methods and equipment standards, of which most contain both English and Metric units of measure.  Revisions have been made in over 122 of the test methods or equipment standards since the Seventeenth Edition, 16 test methods or equipment standards have been discontinued, and 5 new test methods or equipment standards have been added.  A number of test methods and equipment standards have been included in this publication at the request of the AASHTO Subcommittee on Bridges and Structures.  Many of these test methods and equipment standards agree with those of the American Society for Testing and Materials (ASTM).  In all cases where the Association and ASTM test methods and equipment standards are technically identical, or substantially identical with some changes, reference to the ASTM designation number is shown in the heading of the specification.  In past editions, AASHTO has printed ASTM test methods and equipment standards which have been adopted by AASHTO and given an AASHTO designation.  This was done under a long-standing copyright arrangement between AASHTO and ASTM.  After the Sixteenth Edition, ASTM withdrew a number of its test methods and equipment standards from that copyright arrangement, and accordingly, they did not appear in the Seventeenth Edition. However, printing of approximately 50 AASHTO-approved ASTM test methods and equipment standards has been reinstated in the Eighteenth Edition.  Subject areas covered are as follows: hydraulic cement; bituminous materials; soils; aggregates; concrete; brick; joint filler and asphalt plank; culvert pipe and drain tile; metallic materials; miscellaneous; environmental tests; pavement surface characteristics; and painting and traffic marking and signing.]]></description>

      <link>https://trid.trb.org/View/577391</link>
      <description><![CDATA[Results of geotechnical and environmental laboratory tests on atmospheric fluidized bed combustion ash and stoker ash are presented.  The testing program is directed toward assessing the adequacy of using these materials as structural fill in roadway embankment construction.  Geotechnical tests include specific gravity, standard Proctor compaction, permeability, California bearing ratio, strength, and swell tests.  Environmental tests include bulk chemical analysis of major and trace elements, toxicity characteristic leachate procedure, extraction procedure toxicity, and Indiana neutral water leachate tests.  The fluidized bed combustion ash and mixtures with stoker ash exhibit significant cementitious strength increase, and swelling with time.  The implications of test results relative to use as structural fill are discussed.]]></description>

      <title>HEAVY METAL POLLUTION AND THE FISHING INDUSTRY</title>
      <link>https://trid.trb.org/View/391104</link>
      <description><![CDATA[Heavy metals  are discharged into marine habitats in a variety of effluents from natural and man-made sources.  The effects of these metals on fish have, until recently, been assessed by LD50 tests. There is now increasing evidence that sub-lethal concentrations of metals may affect reproduction or embyro and larval stages of fish and their food with the consequence that fish populations are decreasing.  Metal concentrations in fish also result in rejection of exported fish.  Both these effects have economic implications for the fishing industry.]]></description>
