What are the problems with distress surveys, and how can such problems be solved?
What will be an ideal response?
One of the major problems with distress surveys is the variability in results
due to the subjective procedures used, and the concerns about the safety of
pavement surveyors and the hazards associated with their being on the road. The
best solution lies in the use of automated techniques for evaluating distress. This
would remove the survey crew from the hazardous road conditions, and allow for
more consistent results.
Other sources of error are variations in the condition of the highway
segment observed, changes in evaluation procedure, and changes in observed
location from year to year. Some of these variations can be minimized by using the
same pavement location each year by observing pavement condition at regular
intervals of about one mile.
