Project Objective

Conduct applied research to evaluate the performance of bottom ash asphalt mixes.

Project Abstract

Cracks develop in asphaltic pavements due to temperature fluctuations, traffic loading, as well as construction related problems. It is essential that the cracks be sealed to prevent water from infiltrating pavement structures. Highway Departments nationwide invest a significant amount of money every year on crack filling materials. It is important to determine the effectiveness of these materials in sealing the cracks. The main objective of this study is to evaluate the effectiveness of hot poured crack surfacing materials in sealing the cracks.

Task Descriptions

• Perform a literature search on hot poured crack sealing materials.
• Identify three different types of hot poured crack surfacing materials for inclusion in the study.
• Develop laboratory procedures for evaluating the crack filling materials in the laboratory at high and low temperatures.
• Test the crack filling materials according to the procedures developed in the previous task.
• Develop a field evaluation procedure for crack filling materials.
• Perform field evaluation on selected sites where the crack filling materials have been used.
• Performance a comprehensive statistical analysis on the collected data.
• Deliver a final MPC report summarizing the findings of the study.
• Submit a TRB technical paper.
