Statistical deviations in the analysis of asphalt mix properties

Nataša Zavrtanik, Aleksander Ljubič, Goran Turk

Abstract

The main purpose of this research is to establish a method for identifying statistical deviations in the analysis of properties of the asphalt mix AC 22, which are not accidental, but are caused by external factors, such as the change of standards, laboratory equipment, or staff. The analysis was made to determine deviation of correlation coefficients for properties of asphalt mixes divided into two groups. The groups are related to two time intervals, and the computation was repeated by random selection of data within the two groups, so as to determine deviations within the groups.

Keywords
analysis of asphalt mix properties, mean value, variance, correlation coefficient, p-value
