    Site selection and data collection The highway considered in the present study connects North West of Saudi Arabia with South West of Saudi Arabia, and is more than km in length. The study involves the analysis of roughness and distress data only from Cited by: 8. Residual plots play an important role in regression analysis when the goal is to confirm or negate the individual regression assumptions, identify outliers, and/or assess the adequacy of the fitted model.

    As to the country(ies) in which research data was collected, according to Table 2, there is a clear predominance which took place in England (15). There is also a considerable number of studies on TNA in the United States (11). Table 2 Country(ies) in Which Data Collection Occurred #. Country(ies) Number of studies conducted 1. England 15 2.

The rut bar configuration with three sensors is illustrated in the lower portion of figure 1. The rut depths for the two wheelpaths are comput- ed by taking the difference in pave- ment elevation between the wheel- path sensors (sensors 1 and 3) and the mid-lane sensor (sensor 2).

TechBrief: Adequacy of Rut Bar Data Collection Primary Topic: Surface and Other Considerations Description: Technical brief summarizing a study of LTPP transverse profile data to evaluate use of three point and five point rut bar measurement systems to measure rutting in flexible pavements.

adequacy of rut bar data collection The importance of timely corrective action for rutted pavements, coupled with the need for safe and efficient data collection, has led many State highway agencies to use automated survey vehicles to collect the data needed to assess and monitor the extent and severity of pavement rutting.

Adequacy of Rut Bar Data Collection. Analyses of observed pavement performance show that condition data collection frequency can significantly affect performance prediction. Therefore, more frequent data collection for image-based methods can reduce the associated risk in performance prediction and thus be more effective for better decision making for pavement by: 9.

Table 1 shows the original data of a representative rut transverse profile collected by the point-based laser bar. Each profile data consists of three lines.

In the first row, “G40” indicates the identification number of the roadway; “A” represents the upper line, while “” identifies the stake mark which means the profile is located in K1+ by: 2. Adequacy of rut bar data collection.
