Random sampling in performance contracts : comparison between "risk areas" and other areas on a few road objects (English)
Abstract [sv]

Syftet med detta projekt var dels att bedöma hur homogenitet kan mätas och kvantifieras över ett objekt med nylagd asfaltbeläggning och att dels bedöma hur egenskaperna hos dessa asfaltbeläggningar varierar mellan definierade riskytor och övriga ytor. Detta kan sammanfattas i tre olika frågeställningar:

 Fråga 1: Vilka metoder finns för att bedöma homogeniteten på nylagda asfaltbeläggningar?

 Fråga 2: Hur mycket varierar egenskaperna på ytor som bedömts som riskytor jämfört med övriga ytor?

 Fråga 3: Speglar entreprenörens kvalitetsuppföljning resultaten från riskytor eller angränsande ytor?

Abstract [en]

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”?
