Available in PDF, EPUB and Kindle. Book excerpt: Design principles and procedures and maintenance practices for bridge drainage systems are evaluated in this report, which also includes recommendations for improvements on current practice. Bridges should have adequate cross-slope and grade to allow the water to run quickly into drains. Where grades permit, some states carry all the water to catch basins at the ends. An inlet box may be used to collect the runoff. Some states have detailed procedures for determining drain spacing. Debris can be controlled by keeping it out of inlet boxes, accepting and storing it so it cannot go through the system, or transporting it through. Maintenance at regular intervals is the key to the success of a drainage system. Disposal of run off water can be a simple straight drop onto the land or water beneath the bridge or a pipe system to carry the water to the local sewer system. Current practices indicate that deck cross-slope and grade should be less than 2% and 0.5% respectively; that bridge drains may be holes through the deck, fabricated inlet boxes, or catch basins at the ends of the bridge; that inlet areas should be as large as possible; that pipes should have a minimum diameter of 6 in., a miminum radius of 18 in., and a minimum slope of 2%; that cleanout plugs and elbows should be easily accessible; that there should be improved communication between designers and maintenance personnel; and most importantly, that bridge drainage systems should be regularly and carefully inspected and serviced.

Download or read book Guidelines for Cone Penetration Test written by United States. Federal Highway Administration. Implementation Division and published by . This book was released on 1977 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: This manual presents procedures and guidelines applicable to the use of the cone penetration test. It represents the author's interpretation of the state-of-the-art in Dutch static cone testing as of February 1977. Its contents should provide assistance and uniformity to engineers concerned with the interpretation of the data obtained from such testing. Only geotechnical engineers familiar with the fundamentals of soil mechanics and foundation engineering should use this manual. The manual includes: Introduction and review of the general principals concerning cone penetrometer testing. Individual design chapters which address topics such as: pile design, shear strength estimation, settlement calculation and compaction control; and Appendices which present previously published, pertinent information on cone penetrometer testing.

Book excerpt: This report deals with pavement mixture designs and construction operation of field trials on U.S. 69 north of Lufkin, Texas. The binders used in this field trial consisted of pure asphalt cement for the control sections and 30/70 weight percent of a sulphur/asphalt emulsion as the test binder. All elements of the structural (thickness) design were produced in pairs for comparison purposes with the exception of two thinner sections selected to possibly show distress in two or three years. Otherwise, the thickness designs used in the test sections were those specified by the State Department of Highways and Public Transportation in the conventional section of this highway. Preconstruction laboratory evaluations of mixture properties and field laboratory control measurements are included as a part of this report.
