PAVEMENT CRACKING AS RELATED TO ASPHALT HARDNESS

This report presents the results of a limited study to determine if any relationship exists between asphalt hardness and pavement cracking in South Dakota. The project was broken down into three phases: 1. selection of projects of all asphalt types, 2. determination of crack spacing on projects selected, and 3. analysis of data. It was concluded that a definite relationship was found to exist between asphalt hardness and pavement cracking in South Dakota. A regional factor was found to exist with the Black Hills with the result that all asphalts, regardless of hardness, performed extremely well. The majority of cracks that occurred in the projects selected were in a transverse direction. It was also concluded that the stability of asphalt pavements is adequate throughout the state of South Dakota.
