Office of Aviation Research A4 - Shyprykevich, Peter AB - The effectiveness of repair of damaged fiber reinforced composite laminates was investigated; the effectiveness of repair being assessed by the tensile failure load of the repaired laminate. AB - First, tests were conducted measuring the failure loads of laminates repaired either by the scarf, the uniform lap, or the stepped lap technique. Data were generated with the following parameters having been varied: type of material of the damaged laminate, type of repair material, scarf angle and number of external plies in scarf repair, length and number of repair plies in uniform and stepped lap repair, moisture content of the laminate prior to repair, moisture content of the laminate after repair, test temperature, roughness of grinding tool used in preparing the repair surface, and the temperature applied during the cure of the repair patch. The aforementioned parameters were varied over wide ranges, and provided systematic sets of data which shed light on the influence of each of these parameters on the effectiveness of the repair. AB - Second, models were developed for calculating the failure loads of composite laminates repaired by scarf and uniform lap techniques. The models take into account anisotropy of each ply in the laminate and in the repair ply and nonelastic behavior of the adhesive or resin interlayer between the laminate and the repair patch. On the basis of the models, two computer codes were written for generating numerical values of the failure loads. The first code is for calculating the failure loads of laminates repaired by the uniform lap technique, the second for calculating the failure loads of laminates repaired by the scarf technique. Failure loads calculated by the models and the corresponding computer codes were compared with data and good agreement was found between the results of the analysis and the tests.

Given the volume of passenger baggage and the fact that bottles are often elaborately packaged or sealed, manual inspection of a bottle's contents is a difficult challenge. To improve the screening of liquid containers, devices are currently in development to screen bottles. This document describes a plan for collecting critical information about the interface and usability of a bottle contents tester. The assessment will proceed in two stages: a laboratory assessment at the Aviation Security Laboratory at the Atlantic City International Airport in New Jersey and a field assessment. Usability of a bottle test in the optional environment as well as screener and passenger acceptance of bottle contents screening will be assessed.

Office of Operations AB - Traffic Incident Management (TIM) consists of a planned, coordinated, multi-disciplinary process to detect, respond to, and clear traffic incidents so that traffic flow may be restored as safely and quickly as possible. The TIM Capability Maturity Framework has evolved to take advantage of an existing and closely related process called the TIM Self-Assessment. In 2015, TIM SA as aligned with the emerging Capability Maturity Framework (CMF). Today, the framework is formally known as TIM Capability Maturity Self-Assessment (CM SA). Just like the other program area CMFs, the TIM CM SA provided a structured approach to assessing an agency's existing capabilities, and upon completion, provides an action plan for the agency to improve its capability levels. However, in contrast to other frameworks, the TIM CM SA is used for benchmarking State and local TIM programs around the country. For an example of the TIM CM SA national analysis results, see 2018 Traffic Incident Management Capability Maturity Self-Assessment National Analysis Report. The TIM CM SA is organized differently from the other CMFs with three major areas of assessment instead of the six dimensions: Strategic (addresses formalization of TIM programs, TIM training and TIM performance measures); Tactical (addresses TIM laws, policies and procedures for incident response and clearance, and responder & motorist safety); Support (addresses data collection/integration/sharing related questions). The following resources, organized by the three major areas, provide examples from different parts of the country around these topics. These resources provide users of TIM CM SA with relevant information as they consider the results of the TIM CM SA.

Export RIS Citation Information. TY - Brief A2 - United States. Department of Transportation. Federal Highway Administration. Office of Operations AB - The Planned Special Event (PSE) Capability Maturity Framework (CMF) is intended for State and local agencies to assess their current operational capabilities with respect to planned special event traffic management. Planned Special Events include sporting events, concerts, festivals, and conventions occurring at permanent multi-use venues (e.g., arenas, stadiums, racetracks, fairgrounds, amphitheaters, and convention centers). They also include less frequent public events such as parades, fireworks displays, bicycle races, motorcycle rallies, seasonal festivals, marches, and milestone celebrations at temporary venues. These events can significantly impact travel safety, mobility, and reliability; therefore, managing these events requires advanced operations planning, strong inter-agency coordination, frequent communication, and resource sharing. In addition to helping agencies assess their current PSE capabilities, the CMF tool is able to provide a list of concrete actions for improving their PSE operations. The following resources, organized by capability dimensions and sub-dimensions, provide examples of existing capability throughout the country. When multiple examples are available, they are included as "additional examples" in the table.

Federal Highway Administration AB - A parametric study was undertaken to investigate the effects of material properties, geosynthetic configurations, underlying foundations, and facings on the performance of geosynthetic reinforced retaining walls. The parametric study was conducted by using a finite element program SSCOMP. The program had been validated through comparisons with field measurement of many different earth structures. The effects of the following parameters on the performance of geosynthetic-reinforced retaining walls were investigated: the backfill stiffness and strength; the geosynthetic stiffness; the geosynthetic length; the geosynthetic layer spacing; the foundation stiffness and strength; the foundation depth; the surcharge pressure; and the facing rigidity. In view of the complexity of the performance of the walls as affected by the factors investigated, and increasing availability of computers to design engineers, a computer-based design procedure is proposed. The design method involves execution of two computer programs, GSWALL and SSCOMP. The program GSWALL is used to obtain a trial design. The program SSCOMP, which is capable of accommodating all of the above-mentioned factors, is used subsequently to calculate the detailed response of the wall, including wall movements and tensile forces induced in the geosynthetic. The trial design should be modified, using the findings of the parametric study as a guide, until an acceptable design is secured.

The synthetic snow fences were easier to install than the wooden fences because they were lighter (approximately one-fourth of the weight of the wooden fences), and because they stretched easier. They required substantially less room to haul. The snow trapping efficiency of the synthetic snow fences was comparable to that of wooden fences. The result of this study has demonstrated the use of synthetic snow fences as an alternative to the traditional wooden snow fences. However, their installation close to a ranch with grazing bulls is not recommended. Bulls have tendencies to either lean against them or chew on them.

The performance data does not support the use of the rut-resistant composite pavement design. Although there were only a few failures due to stripping, the extent of the failures were significant enough to warrant discontinuing the rut-resistant composite pavement design. The failure mechanism in the RRCP was not due to rutting or cracking, but appears to be directly associated with stripping caused by hydrostatic pressure immediately below the PMSC layer. The conditions which are present when stripping occurs are heavy traffic, high temperatures, and the presence of moisture.

Export RIS Citation Information. TY - Tech Report AU - Hunt, Thomas R. A2 - Colorado. Department of Transportation A3 - United States. Department of Transportation. Federal Highway Administration AB - The first Colorado Department of Transportation (CDOT) installation of polyethylene pipes for culvert use was in 1988, on SH 50, north of Olathe. Five to ten feet of well compacted in-situ material was used as backfill. No obvious deflections occurred in the pipe during or after construction, or as a result of in-service live loads. After three years of service, the pipes have not cracked, melted, or worn, and are in good overall condition. One culvert, however, burned for about ten feet into one end as a result of the ignition of sawdust that had collected in it from a nearby sawmill. This section of pipe was replaced. A literature search found that with proper backfill, loads of 100 ft of fill could safely be supported. Some pipes, however, were reported to have deformed excessively even with small loads. These were for the most part 12 in. and 15 in. diameter pipes that had a thinner wall, and were not well supported. The main advantages of polyethylene pipes are: light weight, easier installation, corrosion resistance, and relatively good aesthetic qualities. Plastic pipe is a current option for use in the 1991 Colorado Standard Specifications. In most cases it will be left up to the contractor to determine which pipe material to use to meet the specifications for each particular project. Adequate wall thicknesses and corrugations should be specified. Only Class 1 or better material, compacted in thin lifts to 95% maximum density, should be used. Extra care should be taken to compact under the haunches. With care, fills of at least 50 ft are possible.

Federal Highway Administration AB - Historically the Colorado Department of Highways (now the Colorado Department of Transportation) has approved roadside sign material based on data obtained using the weatherometer. The weatherometer is a piece of equipment used for performing accelerated weather testing. While the weatherometer gives some comparative performance data related to UV stability and exposure to moisture, the true performance is best measured under actual field conditions. An outdoor exposure deck was constructed to test sign materials for their field performance and expected longevity. Sample materials were split into three pieces, one for the weatherometer testing, one for the outdoor exposure deck, and one to remain in original condition for later comparison. This report describes the construction of the deck, and the sheeting results after three years of exposure to Colorado weather. Sheeting installed on the deck was tested bimonthly for retroreflectance, color retention, and visual defects and compared to the test results of 2,000 hours exposure in the weatherometer. The outdoor exposure deck was found to be impractical for acceptance testing of sheeting materials due to the extreme amount of time the panels must be exposed to sustain sufficient deterioration. Testing with the weatherometer should be continued with the assumption that this test only yields comparative exposure data and is not truly correlated as to time in weatherometer equals a specific time of actual weather.
