This book was released on 1996 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study evaluated the night visibility of waffle tape and paint with large beads, particularly during wet night conditions. Data were collected at two sites along a primary arterial. The evaluation included an examination of (1) the application of the markings, (2) the visibility of the markings using retroreflectometer measurements and subjective assessments, and (3) the costeffectiveness of the markings. The study revealed: (1) compared with paint with standard beads, the waffle tape and paint with large beads were slightly more retroreflective during light rain at night and recovered quicker after flooding out, (2) the marginal improvement in visibility during periods of light rain do not offset the operational problems of applying paint with large beads, and (3) the benefits of waffle tape during light rain do not appear to justify its use solely for wet night visibility. Because of the above findings, snowplowable raised pavement markers, which are very visible in wet night conditions, appear to be more cost-effective. The study recommends that (1) VDOT continue to use and maimain snowplowable raised pavement markers for visibility during wet night conditions, (2) VDOT continue to monitor FHWA's study on all weather pavement markings, and (3) the Suffolk District consider testing nonsnowplowable raised pavement markers to assess their use as a low-cost alternative to improve visibility during wet night conditions where snowplowing occurs infrequently.

Available in PDF, EPUB and Kindle. Book excerpt: The purpose of the evaluation reported here was to determine the feasibility of using raised pavement markers placed in pavement grooves as a guidance aid for motorists during nighttime inclement weather conditions. Emphasis was on the visibility and durability characteristics of the markers as influenced by the method of placing them in pavement grooves. It was concluded that the method employed for placing these raised markers in the pavement is feasible for use as a means of protecting the marker from snowplow damage while providing guidance for motorists. However, it is recommended that this method of placing raised pavement markers in grooves not be used for centerline delineation until a method of installation is available which will decrease the cost of installing the markers.

Book excerpt: Standard Specifications for Construction of Roads and Bridges on Federal Highway Projects is issued primarily for constructing roads and bridges on Federal Highway projects under the direct administration of the Federal Highway Administration. It is also used by the U. S. Forest Service and other Federal agencies on their projects. These specifications are cited as "FP-14" indicating "Federal Project" Standard Specifications issued in 2014 and contain both United States Customary and Metric units of measure. This book outlines the contractual process, including bids, Scope of Work for projects, including materials, construction requirements, equipment, glossary of terms, and much more. Road construction companies, and supply management vendors for the equipment, tools, and pipes needed for constructing Federal highways, as well as engineers, Federal, state, and local Government agencies may be interested to have a copy of this authoritative work available as a reference for any current, and/or future road construction projects
