Title: Load Transfer Restoration with Diamond Grinding on Rigid Pavements: Short-Term and Long-Term Effectiveness
Accession Number: 01622843
Record Type: Component
Abstract: The objectives of this research were to develop nonlinear regression models describing the initial effect and the effect over time of load transfer restoration and diamond grinding (LTR/DG) treatments on pavement serviceability. This research used field data previously collected by Washington State Department of Transportation on pavement sections receiving LTR/DG treatments between 1993-2006. Expanded and simplified models were developed to describe the initial performance change associated with LTR/DG treatment. Considering the simplified model requires knowledge of fewer variables and describes the performance change with less variation, it is recommended for application. Charts were provided to estimate the expected performance change associated with LTR/DG. To achieve the greatest change, LTR/DG treatments should be performed on pavement younger than 30 years. A model was developed to describe the performance loss over time occurring after LTR/DG treatment. The regression model shows a slight increase in pavement condition for the first year or two following treatment, which was a common trend among individual pavement sections. Charts were provided to estimate the expected performance loss associated with LTR/DG. The simplified performance change model can be combined with the performance loss model to estimate the extended service life a LTR/DG treatment provides a particular pavement section. Additional performance change and performance loss models are recommended for LTR/DG treatments in other states and for longer post-treatment periods.
