Available in PDF, EPUB and Kindle. Book excerpt: In the past, culvert pipes were made only of corrugated metal or reinforced concrete. In recent years, several manufacturers have made pipe of lightweight plastic - for example, high density polyethylene (HDPE) - which is considered to be viscoelastic in its structural behavior. It appears that there are several highway applications in which HDPE pipe would be an economically favorable alternative. However, the newness of plastic pipe requires the evaluation of its performance, integrity, and durability; A review of the Iowa Department of Transportation Standard Specifications for Highway and Bridge Construction reveals limited information on the use of plastic pipe for state projects. The objective of this study was to review and evaluate the use of HDPE pipe in roadway applications. Structural performance, soil-structure interaction, and the sensitivity of the pipe to installation was investigated. Comprehensive computerized literature searches were undertaken to define the state-of-the-art in the design and use of HDPE pipe in highway applications. A questionnaire was developed and sent to all Iowa county engineers to learn of their use of HDPE pipe. Responses indicated that the majority of county engineers were aware of the product but were not confident in its ability to perform as well as conventional materials. Counties currently using HDPE pipe in general only use it in driveway crossings. Originally, we intended to survey states as to their usage of HDPE pipe. However, a few weeks after initiation of the project, it was learned that the Tennessee DOT was in the process of making a similar survey of state DOT's. Results of the Tennessee survey of states have been obtained and included in this report. In an effort to develop more confidence in the pipe's performance parameters, this research included laboratory tests to determine the ring and flexural stiffness of HDPE pipe provided by various manufacturers. Parallel plate tests verified all specimens were in compliance with ASTM specifications. Flexural testing revealed that pipe profile had a significant effect on the longitudinal stiffness and that strength could not be accurately predicted on the basis of diameter alone. Realizing that the soil around a buried HDPE pipe contributes to the pipe stiffness, the research team completed a limited series of tests on buried 3 ft-diameter HDPE pipe. The tests simulated the effects of truck wheel loads above the pipe and were conducted with two feet of cover. These tests indicated that the type and quality of backfill significantly influences the performance of HDPE pipe. The tests revealed that the soil envelope does significantly affect the performance of HDPE pipe in situ, and after a certain point, no additional strength is realized by increasing the quality of the backfill.

Book excerpt: It is generally accepted that high density polyethylene pipe (HDPE) performs well under live loads with shallow cover, provided the backfill is well compacted. Although industry standards require carefully compacted backfill, poor inspection and/or faulty construction may result in soils that provide inadequate restraint at the springlines of the pipes thereby causing failure. The objectives of this study were: 1) to experimentally define a lower limit of compaction under which the pipes perform satisfactorily, 2) to quantify the increase in soil support as compaction effort increases, 3) to evaluate pipe response for loads applied near the ends of the buried pipes, 4) to determine minimum depths of cover for a variety of pipes and soil conditions by analytically expanding the experimental results through the use of the finite element program CANDE.

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.
