UTILIZATION OF BOTTOM ASH IN ASPHALT MIXES
This research project used field and laboratory evaluations to study the possibility of incorporating bottom ash in asphalt mixes. For the field portion of this research, a pavement test section was constructed. This test section included control and bottom ash asphalt mixes. The laboratory evaluations involved design and accelerated testing of control and bottom ash mixes. In addition, the control and bottom ash asphalt mixes used to construct the field test sections were evaluated. Laboratory testing was accomplished by using the Georgia Loaded Wheel Tester (GLWT) and Thermal Stress Restrained Specimen Tester (TSRST). The GLWT was used to evaluate the high temperature rutting characteristics of asphalt mixes. The TSRST was used to evaluate the low temperature cracking characteristics of the asphalt mixes. Initial observations of the test road indicated no difference in performance between the control and bottom ash pavement sections. Laboratory evaluations indicated the various bottom ash asphalt mixes possess significantly different high temperature rutting and low temperature cracking characteristics.
