Available in PDF, EPUB and Kindle. Book excerpt: This report presents the findings and recommendations on the evaluation of High Density Polyethylene (HDPE) Pipe resulting from a 1996 Transportation Enhancement/Hazard Elimination Project in Martin, South Dakota. This was the first project where HDPE pipe was allowed to be installed under a state highway in South Dakota. Department researchers installed instrumentation and conducted deflection testing on a 760 mm (30 in) HDPE pipe installed under US Highway 18 in Martin, South Dakota. A horizontal inclinometer probe was used to determine vertical heave or settlement. Surface profiles were monitored with a Dipstick® Floor Profiler. Thirteen separate sets of measurements were taken between August 1996 and June 1997. Costs were determined for installation and delivery of both HDPE pipes and reinforced concrete pipes (RCP). Neighboring states were surveyed to determine their costs for storm sewer pipes as well as specifications for installing HDPE pipes. Recommendations were made to allow the installation of HDPE pipe based on information received from the state survey, literature reviews, and the results of the Martin, South Dakota Project.

This book was released on 2018 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: TRB's National Cooperative Highway Research Program (NCHRP) Research Report 870: Field Performance of Corrugated Pipe Manufactured with Recycled Polyethylene Content explores the use of corrugated high density polyethylene (HDPE) pipe manufactured with recycled content and proposes guidelines for manufacturing these pipes to ensure they meet the service life requirements for the given application. This project expounded on the research published in NCHRP Report 696. The research consisted of manufacturing several large diameter corrugated HDPE pipes out of various blends of virgin and post-consumer recycled (PCR) materials commonly used in land drainage applications and evaluating these pipes in the field and laboratory to determine their service life in typical installed conditions. PCR materials were the focus of this project as they are more readily available and typically used in the corrugated HDPE pipe industry than post industrial recycled materials. However, the research is applicable to both types. -- cc. http://www.trb.org/main/blurbs/176741.aspx.

This book was released on 2015 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two field tests were conducted to investigate the field performance of steel-reinforced high-density polyethylene (SRHDPE) pipes during installation and under traffic loading. One test site was located on E 1000 road in Lawrence, KS, which is close to Clinton Lake. Three SRHDPE pipes with a diameter of 3 ft and a length of 24 ft were buried in a 6 ft wide trench with 2 ft thick soil cover. This test site had two test sections: one section was filled with Aggregate Base Class 3 aggregate (AB3) and the second section was filled with crushed stone. The second field study was conducted at a Kansas Department of Transportation (KDOT) storage yard in Kansas City, KS. Four 6 ft long SRHDPE pipes with a diameter of 2 ft were connected and buried in a trench with a dimension of 4.6 ft wide × 27.5 ft long × 4.2 ft deep. Two types of backfill material were also used in the trench, namely, AB3 aggregate and crushed stone. Earth pressures, pipe deflections, and pipe strains on plastic valley, plastic cover, and steel ribs were monitored during pipe installation and under static loading on both test sites. The test results from the pipe installation and static loading showed that (1) the vertical arching factor (VAF) on the top of the pipe was approximately 1.1 and the lateral earth pressure coefficient was approximately 0.65; (2) the peaking deflection was observed in both field tests in a range of 0.25 to 1.80% (the peaking deflection in the AB3 section was greater than that in the crushed stone section); (3) the maximum strain of the pipe occurred on the plastic valley in the longitudinal direction at the pipe crown, which was in a range of 0.4-0.6% and much lower than the strain limit of 5% suggested by the American Association of State Highway and Transportation Officials (AASHTO, 2012); and (4) the Giroud and Han (2004) method and the AASHTO (2012) method could reasonably estimate the earth pressure on the pipe under static loading, while the Iowa Formula could estimate the pipe deflection during installation and caused by static loading. The earth pressures, the pipe deflections, and the strains of the pipes in the Lawrence site were monitored for 680 days and all increased with time. Two empirical correlations were proposed to calculate the VAF and the pipe stiffness factor at a given time. The AASHTO (2012) design methods for metal pipes and high-density polyethylene (HDPE) pipes were modified for SRHDPE pipes based on the laboratory and field test results. A design procedure for SRHDPE pipes is proposed and illustrated by a design example.

This book was released on 2014 with total page 99 pages. Available in PDF, EPUB and Kindle. Book excerpt: The current and forecasted major challenge faced by water utilities is delivering potable water efficiently with minimum loss to end users. Water pipe failure has negative impact not only local communities but also on the nation's economy. The American Water Works Association (AWWA) has estimated that it will cost over $250 billion to replace and renew the nation's water pipes over the next 20 years. According to the 2009 American Society of Civil Engineers (ASCE) Report Card, seven billion gallons of water are lost in this country every day! Every pipe has unique properties with advantages and limitations. During a pipe's life cycle, failures occur due to numerous factors such as age, loading conditions, environmental conditions, installation quality, manufacturing procedures, operation and maintenance strategies and so on. The very limited information on High Density Polyethylene (HDPE) pipes created the need for this research. This thesis is a preliminary step towards understanding the HDPE pipe performance for lower and larger pipe size diameters. To achieve the objectives of this research, a nationwide survey was carried out. For the respondent utilities, the average annual failure rate for the smaller diameter pipe is 0.5 per 100 miles. Most frequent causes of failures occurring in small diameter pipes were due to joint failure. Due to lack of enough large diameter HDPE pipe respondents, the results were not conclusive.

Download or read book Polyethylene Pipes for Use as Highway Culverts written by Thomas R. Hunt and published by . This book was released on 1991 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Steel reinforced high density polyethylene pipes are gaining popularity these days because of their good performance and advantages of them in comparison to the other pipe materials. By inverting the steel ribs vertically in to the HDPE materials, strength of steel and flexibility and light weight of HDPE materials have been combined. However due the limited study in this area, the failure modes and design parameters are not classified. This study investigates the behavior and failure modes of SR-HDPE pipes under the simulated soil load and compares the results with the data obtained from the test on corrugated metal pipe under the identical test scenario. Full-scale experimental tests were conducted with soil boxes in order to determine if the steel ribs in SR-HDPE act continuously throughout the pipe structure. Local and global deformations of the pipe were monitored with displacement transducers and strain gauges, respectively. Strain gauges were placed at two sections of the pipe. Each section contained six strain gauges at the crown, springline, and invert. Displacement transducers were installed in two sections along the pipe (middle and 12 in.(31 cm) from the end). Each section was capable of monitoring the vertical deflection and the horizontal deflection was measured at mid section. The load was applied through a hydraulic cylinder, and a rigid concrete slab. The data from these sensors were recorded and reported to identify the response of the pipes with regard to strength and serviceability. Three different pipe sizes (24 in. (61 cm), 36 in. (91 cm), and 48 in. (122 cm)) were tested in this situation and three different concrete slabs were cast whose dimensions were fixed by the pipe length which was 4 ft. (122 cm) and pipe and its width varied based on internal diameter. The results showed that the CMP pipe has higher stiffness and load carrying capacity. Also CMP exhibited more ductility before the failure. The governing failure mode of the SRHDPE pipe tested was lateral buckling of the ribs along the horizontal axis of the pipe at crown and springlines. This was due to the premature buckling of the HDPE material supporting the steel ribs, thus, causing discontinuous steel action. This study shows that the behavior of the SR-HDPE is different than the CMP pipe. By inspecting the pipe after reloading and removing from the soil box, three failure lines (crease) for 24 in. (61 cm) SR-HDPE and four failure lines for 36 in. (91 cm), and 48 in. (122 cm) SR-HDPE which is explained by the higher hoop capacity of the 24 in. (61 cm) SR-HDPE pipe in comparison with other pipe sizes. However CMP pipes exhibited a continuous hoop type buckling and smooth plastic hinge.
