This book was released on 1962 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: Paper 1: An analysis is presented of some 6,000 mi of pavement profile obtained by the Michigan pavement performance study in the 3-year period of 1958-59-60. Paper 2: Using the criterion of pavement condition as defined in this paper, it is possible to estimate the dynamic force that one wheel of a vehicle will exert on a highway. Paper 3: The method used to measure road profile and techniques used to establish the accuracy of these measurements are described. Paper 4: Various modifications made by Illinois are described in constructing its roadometer as well as the tests in which it has been subjected and its use in rating Illinois pavements under the present serviceability concept following correlation of the device with the AASHO road test profilometer.

Available in PDF, EPUB and Kindle. Book excerpt: Road roughness is gaining increasing importance as an indicator of road condition, both in terms of pavement performance, and as a major determinant of road user costs. This paper defines roughness measurement systems hierachically into four groups, ranging from profilometric methods (2 groups), through response type road roughness measuring systems (RTRRMS's), and, subjective evaluation. The International Roughness Index (IRI) is defined, and the programs for it's calculation are provided. The IRI is based on simulation of the roughness response of a car travelling at 80 km/h. The report explains how all roughness measurements can be related to this scale, also when travelling at lower speeds than 80 km/h. The IRI emerges as a scale that can be used both for calibration and for comparative purposes.

Available in PDF, EPUB and Kindle. Book excerpt: Pavement surface texture is measured in a variety of ways in Virginia. Two methods commonly used are ASTM E 965, Standard Test Method for Measuring Pavement Macrotexture Depth Using a Volumetric Technique, known as the "sand patch" test, and ASTM E 2157, Standard Test Method for Measuring Pavement Macrotexture Properties Using the Circular Track (CT) Meter. In September 2005, staff from the Virginia Transportation Research Council inquired about using the Digital Surface Roughness Meter (DSRM®) to measure the surface texture of several concrete and asphalt surfaces. Measurements were taken on concrete and asphalt surfaces using the DSRM®, CT meter, and sand patch test, and the results were compared. From the data obtained, there appears to be a good correlation among the results of the three methods. The DSRM® and sand patch tests appear to be more accurate on surfaces that are not uniform. However, this may be because the center of the rotating arm of the CT meter may have missed particular non-uniform areas on the testing surface. The use of the DSRM® and CT meter devices also reduces the probability of human error. The sand patch test is exposed to a greater probability of human error; it is a test that cannot be performed quickly without comprising accuracy. The DSRM® is a better device to use under a time constraint.

Download or read book Pavement Condition Measurement Needs and Methods written by and published by . This book was released on 1978 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study was to investigate current practice, select the best techniques, and recommend equipment and methodology suitable for pavement condition evaluation. It consisted of visits to chosen States to determine pavement properties that can be measured and provide data for management decisions. The information collected was supplemented with a literature search and a limited firsthand review of equipment in use. The recommended roadway property measurements needed for pavement condition evaluation as inputs to pavement management systems are skid resistance, roughness, structural capacity, and pavement distress used to assist in pavement repair strategy. Suggestions on data processing, storage, and retrieval are also given in the report.
