Available in PDF, EPUB and Kindle. Book excerpt: Excess moisture has been identified as a cause for stripping, raveling, debonding, and rutting in flexible pavement [ODOT, 2016a]. The Ohio Department of Transportation (ODOT) has been getting substantially less than the expected 15 year service life after a resurfacing project, particularly on those routes without drainage. Providing drainage may help mitigate the premature failures ODOT is seeing on their rural routes. Section 205 of the 2016 Ohio DOT Pavement Design Manual (PDM) requires subsurface drainage on all new projects and recommends aggregate drains be used with bituminous surface treated and aggregate shoulders. Installing aggregate drains by contract during resurfacing has become costly for ODOT. This project was completed in two phases. The first phase focused on current practices of drainage installation on rural routes and on identifying available equipment for use by county crews. Phase 2 included a field evaluation to evaluate cost effective options for drainage incorporating the findings and recommendations from Phase 1. The Phase 1 evaluation identified aggregate drains as the appropriate drainage method and the rock saw as the most efficient equipment for aggregate drain installation. In Phase 2 aggregate drains were constructed by ODOT's Marion County personnel in forty test sections on State Route 529 using the rock saw and the backhoe. Drains were not installed in four sections which served as control sections, for a total of forty-four sections. Aggregate drains were installed using backfill meeting AASHTO #8, #57, and #4 gradations as well as a porous concrete backfill. Other factors evaluated included varied spacing between drains, trenches with and without fabric, compacted and un-compacted backfill, and narrow and wide trenches. Dynamic cone penetrometer testing was conducted before and after the monitoring period. The sections were monitored every four months for a one year period by testing with the falling weight deflectometer and measuring in-situ volumetric moisture.

Download or read book Groundwater and Surface Water Pollution written by David H.F. Liu and published by Routledge. This book was released on 2019-01-22 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: Groundwater and Surface Water Pollution contains almost all the technical know-how required to clean up our water supply. It provides a survey of up-to-date technologies for remediation, as well as a step-by-step guide to pollution assessment for both ground and surface waters. The book defines groundwater, aquifers and surface water and discusses the physical properties of soils, liquids, vadose zones and aquifers. It emphasizes controlling nonpoint source pollution, best management practices, and an integrated management approach. The editors cover not only engineering but also legal, medical, agricultural, meteorological, biological and other fields of study. They reach beyond the simplistic hydrological cycles usually addressed to the complexities encountered by rapidly-changing land-use patterns. In addition to focusing on causes, effects, and remedies, Groundwater and Surface Water Pollution stresses reuse, recycling, and recovery of resources. Nature does not cause pollution. Through total recycling, we can, like nature, make resources out of wastes. Béla G. Lipták speaks on Post-Oil Energy Technology on the AT&T Tech Channel.

Download or read book Gravel Roads written by Ken Skorseth and published by . This book was released on 2000 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this manual is to provide clear and helpful information for maintaining gravel roads. Very little technical help is available to small agencies that are responsible for managing these roads. Gravel road maintenance has traditionally been "more of an art than a science" and very few formal standards exist. This manual contains guidelines to help answer the questions that arise concerning gravel road maintenance such as: What is enough surface crown? What is too much? What causes corrugation? The information is as nontechnical as possible without sacrificing clear guidelines and instructions on how to do the job right.
