Evaluation and Correlation of Lab and Field Tensile Strength Ratio (TSR)211 Procedures and Values in Assessing the Stripping Potential of Asphalt Mixes

摘要

The research study focused on investigations of the extent to which the Wisconsin211u001easphalt pavements were affected by moisture damage and the extent to which the 211u001elaboratory moisture damage results correlate with field performance. The 211u001eprediction of moisture damage is currently performed in Wisconsin using the 211u001eprocedure AASHTO T-283, Tensile Strength Ratio (TSR) on hot mix asphalt. The 211u001eobjectives of this study were to (1) determine if the current procedure is 211u001ecapable of predicting the moisture damage of the mixes in the field; (2) 211u001edetermine if Wisconsin pavements have moisture damage problems based on 211u001elaboratory and field TSR values; and (3) determine the extent of moisture damage 211u001eand the consequences on pavement performance based on cores extracted from 211u001eselected pavement sections.
