oa Civil Engineering = Siviele Ingenieurswese - An assessment of the standard deviation of test results on a roadworks project

Volume 24, Issue 2
  • ISSN : 1021-2000



This article assesses the spread and consistency of results from different tests carried out on a road project. The aim is to understand the possible causes and effects of variations between results, in order to assist the construction team in the planning, execution and monitoring of construction works. It should be noted that huge variations within a set of results may make the process of producing the test items more expensive, since the COLTO2 acceptance limit L increases for higher sample standard deviation.
