Investigation and Quatification of Factors Affecting Aggregate Specific Gravities as Determined by KDOT Test Method KT-6

The objective of this project was to identify and quantify the factors affecting individual aggregate specific gravities and the ultimate effect on Superpave volumetric calculations. Kansas State University has two statistical software, SOURCES OF VARIATION ANALYSIS (SOVA) and MULTIPLE CORRELATION ANALYSIS (MCA), which are capable of identifying and quantifying factors (such as, aggregate fractions retained or passing a certain sieve size) which are the root causes of this problem. It is anticipated that the existing data will be analyzed using SOVA and MCA to identify the critical sieve sizes. The findings will then be calibrated by doing actual laboratory tests on the individual aggregates and eventually, doing Superpave mixture design and analysis. A formal report was not published.
