Abstract
Road surface condition evaluation involves the collection Of a lof Of data on different types of distresses. •lie exercise consumes a lot Of resources if the whole road section length is sureeyed and may be prone to errors as a result Of surveyors' fatigue. It is therefore important Io develop n reprevntative sample to be used When road condition manually. This study aimed nt determining sample size for condition evaluation of local collector access roads in urban areas in Tanzania. Two such roads namely l.ufungira and Kilimahewn roads respectively were selected for the study. It is recommended that a section sample of 20 m long from the beginning of n JOO section be used in evaluating the pavement surface condition Of such roads. This will result in a reasonably nccnrnte representation Of the condition of the whole section with huge savings in resources.
