Book Description
A recent study in Australia has shown that there is a relation between low pavement macrotexture and crash incidences on highways. However, literature documents no such research in the United States. This study focuses on evaluating the role of pavement macrotexture in crashes on selected roads in the state of North Carolina (NC). Pavement macrotexture refers to variations in the road surface in the range 0.02" (0.5 mm) to approximately 2" (50 mm). Laser profilometer data obtained from the NC Department of Transportation (NCDOT) is processed to calculate estimated pavement macrotexture at one-sixteenth of a mile interval according to the ASTM standards. Crash data collected over the same lengths of the corridors were integrated with the calculated pavement macrotexture. Scatter plots, bivariate analysis and multivariate analysis showed that a strong relationship exists between pavement macrotexture and crash incidences on NC roads. Analyses and evaluation indicate that crashes decrease with increase in pavement macrotexture on NC roads. Pavement macrotexture greater than or equal to 0.06" (but typically less than 0.12") would be most appropriate to provide safe and efficient transportation to road users.

Mechanical Retexturing of Roads

ISBN : 9780727727992
Book Description
Retexturing of road surfacings by mechanical means in order to restore skidding resistance has been used for some years in the UK, because it is inexpensive, quick and takes advantage of the material already present. This report details the results of the first systematic study to assess the performance and durability of various treatments. Four techniques (scabbling, bush hammering, orthogonal flail grooving and shot-blasting), were studied in road trials, and their efficacy was assessed over a three year period. It was found that, when selected appropriately for a particular site, retexturing treatments are useful tools to enhance the skidding resistance of a surfacing which is at or near its investigatory level. The process can be used all year round and can provide two to three summers of enhancement under typical trunk road conditions.
Asphalt Surfacings

Publisher : CRC Press
Page : 425 pages
File Size : 36,23 MB
Release : 2002-11-01
Category : Architecture
ISBN : 0203477634
Book Description
Asphalt Surfacings has been written as a reference to the various asphalt course materials and surfacing treatments that are currently available to engineers, enabling them to select the materials and/or treatment that are appropriate for use on specific sites. Appropriate reference is made to the lower structural layers as the properties of all layers interact in producing the required pavement. The current established position in the UK and the emerging developments throughout the UK and Europe are covered. The contributors are all acknowledged authorities on their particular topics selected from every part of the highway engineering industry to achieve a balance between the various approaches required by the different functions they perform.
Asphalt Mixture Specification and Testing
Author : Cliff Nicholls
Publisher : CRC Press
Page : 161 pages
File Size : 46,24 MB
Release : 2017-05-12
Category : Technology & Engineering
ISBN : 1351788663
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.
