Stickprov vid utförandeentreprenader: jämförelse mellan ”riskytor” och övriga ytor på några vägobjekt


The purpose of this project was to evaluate how the homogeneity can be measured and quantified over a section with newly laid asphalt pavement and determine how the properties varies from defined risk areas and other areas. This can be summarized in three different questions:

 Question 1: What methods are available to measure the homogeneity of newly laid asphalt pavements?

 Question 2: How much will the properties of the surface identified as risk areas, compared to other areas, vary over a defined asphalt pavement section?

 Question 3: Are the results from the contractor’s quality control equal to results from “risk areas” or “adjacent areas”?
