Book Description
Assessment of current technology for collecting and analyzing longitudinal runway profiles to recommend a method for Transport Canada use. Runway longitudinal profile data for 5 runways were collected using a Digital Incremental Profiler, along with that for 4 other runways, and were analyzed using surface profile - travelling straight edge, root mean square vertical acceleration, and international roughness index methods. Each of the pavement profiles was analyzed using the runway roughness analysis program, an MS-DOS software program. A complementary field study was completed to allow correlation between the roughness values measured using the portable universal roughness device, the maysmeter, and the riding comfort index procedures and the 3 methodologies.

Book Description
This project is the first phase of a proposed larger research effort whose goal is twofold: 1) to determine effective guidelines for collecting and processing road profiles; and 2) to determine, insofar as possible, the specific causes of the poor repeatability in the data obtained by the present Kansas Department of Transportation (KDOT) Pavement Management System.

Book Description
A roughness of the road profile as an inherent pavement surface characteristic is of importance in pavement management. Roughness measurements are used for dividing the road section into statistically homogeneous units, establishing the preferences for maintenance and rehabilitation, and in other aspects of pavement surface characterization. Roughness characteristics are variable, and the method of obtaining the measurements as well as equipment specifications have significant effect on the processing and interpretation of the results. The most basic aspect of measurement capability is repeatability, and the measurement system cannot be accepted without a relatively high level of repeatability. For the purposes of repeatability studies, paired series of roughness measurements have been collected at the Israeli Public Works Department at the same road section under the same conditions for the section, device, and operator. The results of the repeatability studies include descriptions of statistical peculiarities of roughness measurements for each profile involved in the analysis, mutual behavior of compared measurements, as well as repeatability characteristics of the measurement system.
