ASSESSMENT OF LONG-TERM PAVEMENT PERFORMANCE PROGRAM MANUAL DISTRESS DATA VARIABILITY: BIAS AND PRECISION. The use of manual survey methods within the Long-Term Pavement Performance (LTPP) program for the collection of distress data has drastically increased both in intensity and in coverage over the past couple of by: The primary source of data are the results of a distress survey conducted on 12 pavement test sections, including 6 asphalt concrete and 6 portland cement concrete pavements.
Distress surveys were performed by experts, individual raters, and 2-person teams. Evaluations of surface distresses in pavements, such as cracking, bleeding, and raveling, are often used as one component of overall pavement condition indexes.
Both manual and automated survey met. When distress data are collected as ordinal values, the variability may be determined by comparison of pairs of ranked values.
This paper presents one rank correlation method, Kendall’s correlation coefficient, and illustrates how it can be used to assess variability in ordinal distress data collected through manual surveys. version, which was a significant revision to the former “ODOT Distress Survey Manual” that incorporated changes needed to comply with new federal requirements for pavement data collection and reporting mandated in ODOT has collected pavement distress information on the State Highway System since the early ’s.

In order to optimize the road pavement management and guarantee satisfactory mobility conditions for all road users, the Pavement Management System (PMS) is an effective tool for the road manager. An effective PMS requires the availability of pavement distress data Cited by: (i) Pavement Distress Measurements: ASTM D Standard Practice for Roads and Parking Lots Pavement Condition Index Surveys.

Two separate surveys are used to collect pavement condition data. First, a windshield survey is used to collect the severity and extent of surface cracking and other specific types of distress in the pavement.
The windshield survey is also used to update roadway characteristics and inventory information, such as. Automated pavement distress data collection procedures are available, but all of the available procedures and equipment do not necessarily reproduce the pavement condition index values from manual surveys.
These differences in pavement condition index values from different distress data collection methods can lead to substantially different. Pavement Distress Surveys in the Strategic Highway Research Program's Long-Term Pavement Performance Study DIMITRIOS G.

The authors continued that the automated system. REPEATABILITY AND REPRODUCIBILITY OF MANUAL PAVEMENT DISTRESS SURVEY METHODS. Manual survey costs usually increase with the decrease in the subjectivity of the method chosen because of the inclusion of more details in the survey.
Thus, it is important to find the tradeoff between cost and subjectivity. Toggle navigation. Home; Collections; Recent Additions; Public Access; Submit Content; About ROSA P; About; Help. Work has been done by LTPP primarily with manual surveys, but more is needed with automated data for network purposes.
â ¢ Furthermore, it is necessary to develop data on typical year-to-year changes in pavement distress quantities as well as typical precision and bias statements, such that realistic and meaningful QA provisions can be incor. verifying reasonableness and completeness of the pavement condition survey, and conducting audits of the pavement distress data.
