Asphalt Mixture Specification and Testing
Author: Cliff Nicholls
Publisher: CRC Press
ISBN: 1351788663
Category : Technology & Engineering
Languages : en
Pages : 161
Book Description
This guide reviews the way asphalt mixture can be specified, with particular emphasis on the test methods used to measure performance. The advantages and limitations of the tests are described for measuring the desired property, and engineers can specify a test according to the material’s use. The book starts with a resume of specifications and their relative advantages and disadvantages for different situations. Then different properties are discussed in terms of: their specification; the test methods that can be used (primarily the EN 12697 suite of European methods, of which the author has been responsible for drafting); the extent to which the results predict performance; the levels that can be achieved with different asphalt mixes and types; what levels, if any, should be specified in various situations and pavement layers; and which other properties are adversely affected by enhanced performance. The final section covers various aspects of sustainability, with a strong emphasis on durability. Better understanding should enable clients and consultants who specify pavements to produce durable asphalt pavements more economically, and also help asphalt producers and students trying to understand the black art of asphalt.

Guidance for the Selection, Use, and Maintenance of Cable Barrier Systems
Author:
Publisher:
ISBN: 9780309258425
Category : Roads
Languages : en
Pages : 148
Book Description
This report provides guidance for the selection, use, and maintenance of cable barrier systems. While cable barrier systems have been in use for more than 70 years, their use has been on the rise and is expected to continue in the future. The increase in use of cable barrier systems has been attributed to the success rate in keeping vehicles from crossing the median, reducing roadway departures, and decreasing impact severity. Due to advancements in cable barrier system technology, installation and repair costs are lower and cable barrier use has increased in varying roadway environments. Safety studies, although limited, have shown that cable barriers help reduce those median cross-over collisions that lead to some of the most severe head-on type crashes. This document will be of particular interest to design, maintenance, traffic, and safety engineering professionals.
