Book Synopsis Inspecting and Cleaning Subsurface Drain Systems by : L. B. Grass
Download or read book Inspecting and Cleaning Subsurface Drain Systems written by L. B. Grass and published by . This book was released on 1975 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diagnosis of drain failure at an early stage is extremely important to detect and correct the problem before crop losses become serious or topsoil is damaged. Subsurface drainage systems are expensive, long-term investments but they are important to modern mechanized agriculture. The farmer can protect his investment and assure continuing adequate performance of his drainage system by initiating an inspection and maintenance program as a regular part of his farming operations. Drain performance should be evaluated at least once a year on a regular basis and at any time there is a hint of a developing drainage problem.
Book Synopsis Performance of Subsurface Drains at Selected Airfields During the 1960 Frost Melting Period by : William C. Sayman
Download or read book Performance of Subsurface Drains at Selected Airfields During the 1960 Frost Melting Period written by William C. Sayman and published by . This book was released on 1964 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the 1960 frost melting period, the performance of subsurface drainage systems was investigated at selected airfields in the northern continental United States by periodic observations at manholes and/or risers. Records of air temperature, subsurface temperature, and precipitation were also maintained. The observations were one-time 'spot' notations, intended to determine the feasibility of performing more comprehensive studies and no quantitative measurements were undertaken; nor do the data obtained permit evaluation as to the overall effectiveness of the inspected systems or the validity of the criteria used in their design. However, the study showed that the observed subdrain systems were generally performing their function of removing subsurface water. The study also confirms the need for periodic inspection and maintenance of all subsurface systems. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Reliable subsurface drainage systems for groundwater table and salinity control are needed to maintain or enhance the productivity of irrigated lands and to contribute to the rural development of lowlands in the humid tropic. This publication presents guidelines to assess the need for envelopes and for the selection of appropriate materials (i.e. pipes and envelopes) for the proper and lasting performance of subsurface drainage systems. In addition, it also contains guidelines for adequate installation and maintenance of drainage materials as well as the required specifications and standards of such materials, which may be used in tender documents for implementation of subsurface drainage works. Practical guidelines for the implementation of laboratory and field investigations to evaluate the performance of drainage materials have also been included.--Publisher's description.

Book Synopsis Pavement Subsurface Drainage Systems by : Barry Rodney Christopher
Download or read book Pavement Subsurface Drainage Systems written by Barry Rodney Christopher and published by Transportation Research Board. This book was released on 1997 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: This synthesis will be of interest to geologists; hydrologists; geotechnical, pavement, construction, and maintenance engineers; and researchers. State department of transportation (DOT) program managers and administrators will also find it of interest. The synthesis describes the current state of the practice for the design, construction, and maintenance of pavement subsurface drainage systems. It provides information on the positive effects of good subsurface drainage and the negative effects of poor subsurface drainage on pavement surfaces. This report of the Transportation Research Board presents data obtained from a review of the literature and a survey of the state DOTs. It is a supplemental update to NCHRP Synthesis of Highway Practice 96, Pavement Subsurface Drainage Systems (1982). The synthesis provides a supplement to design issues not found in Synthesis 96, but faced by current designers, e.g., type and quality of aggregate, compaction requirements for open-graded aggregates, asphalt and cement binders, and use of geosynthetics. In addition, it describes the effects of design, construction, and maintenance decisions on the performance of pavement subsurface drainage systems.

Book Synopsis Evaluating Roadway Subsurface Drainage Practices by : Halil Ceylan
Download or read book Evaluating Roadway Subsurface Drainage Practices written by Halil Ceylan and published by . This book was released on 2013 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: The bearing capacity and service life of a pavement is affected adversely by the presence of undrained water in the pavement layers. In cold winter climates like in Iowa, this problem is magnified further by the risk of frost damage when water is present. Therefore, well-performing subsurface drainage systems form an important aspect of pavement design by the Iowa Department of Transportation (DOT). However, controversial findings are also reported in the literature regarding the benefits of subsurface drainage. The goal of this research was not to investigate whether subdrains are needed in Iowa pavements, but to conduct an extensive performance review of primary interstate pavement subdrains in Iowa, determine the cause of the problem if there are drains that are not functioning properly, and investigate the effect of poor subdrain performance due to improper design, construction, and maintenance on pavement surface distresses, if any. An extensive literature review was performed covering national-level and state-level research studies mainly focusing on the effects of subsurface drainage on performance of asphalt and concrete pavements. Several studies concerning the effects of a recycled Portland cement concrete (RPCC) subbase on PCC pavement drainage systems were also reviewed. A detailed forensic test plan was developed in consultation with the project technical advisory committee (TAC) for inspecting and evaluating the Iowa pavement subdrains. Field investigations were conducted on 64 selected (jointed plain concrete pavement/JPCP and hot-mix asphalt/HMA) pavement sites during the fall season of 2012 and were mainly focused on the drainage outlet conditions. Statistical analysis was conducted on the compiled data from field investigations to further investigate the effect of drainage on pavement performance. Most Iowa subsurface drainage system outlet blockage is due to tufa, sediment, and soil. Although higher blockage rates reduce the flow rate of water inside outlet pipes, it does not always stop water flowing from inside the outlet pipe to outside the outlet pipe unless the outlet is completely blocked. Few pavement surface distresses were observed near blocked subsurface drainage outlet spots. More shoulder distresses (shoulder drop or cracking) were observed near blocked drainage outlet spots compared to open ones. Both field observations and limited performance analysis indicate that drainage outlet conditions do not have a significant effect on pavement performance. The use of RPCC subbase in PCC pavements results in tufa formation, a primary cause of drainage outlet blockage in JPCP. Several useful recommendations to potentially improve Iowa subdrain performance, which warrant detailed field investigations, were made.
