Maintenance-Level-of-Service Evaluation Procedure for Texas (1968-1F)

The level of maintenance within the state of Texas varies to a substantial degree. Desirably the maintenance would be a reasonably uniform level across all the various essential components. The purpose of the project was to devise methods for objectively measuring the essential elements maximizing automated data collection techniques.|The development team has reviewed the literature on maintenance evaluation. Three sources stand out: ROCOND 87 and ROCOND 90 from Australia, the Virginia Program, and the Florida Program, Each of these sources has helped shape the recommended evaluation procedure for Texas.|The various maintenance elements were divided into seasons of the year to adopt to the time when that element would be critical. Those that are not time dependent were distributed to balance the data collection workload. Many continuous elements, such as vegetation, roadside drainage, etc., are scheduled for video tape data collection. Selected features will be collected visually by the data collection operator, noxious weeds, pavement edge drop-off, and cross drainage structures are typical examples.|A random site selection program has been prepared to obtain 0.15 km (0.1 mile) length sample sites. The evaluation program has been conceptually developed and has been fully field tested prior to full scale implementation.
