THE VARIABILITY IN DIMENSIONS OF "AS CONSTRUCTED" ARTERIAL ROADS, WITH PARTICULAR REFERENCE TO PAVEMENT LEVELS

This paper was presented at session 21 - quality control. Dimensional variability achieved on sections of 21 arterial roads constructed under the supervision of the six state road authorities is presented and analysed. The road dimensions considered in this paper comprise pavement levels relative to design, pavement thickness and surface shape. The variability achieved in pavement levels at the various stages of construction is shown to give sufficient indication of variation in pavement thickness and surface shape. Methods of level control were found to represent the major source of variation between results achieved on the different jobs. Hence, these results were grouped into four significantly different categories. This finding allows the selection of the appropriate method for the quality standard required. Significant differences were found between means of level measurements of sub-samples along the test sections, but not between the corresponding standard deviations. This emphasises the need for closer survey control to achieve design standards. (TRRL)
