Evaluation of Rubblization Projects in Ohio
This study was initiated to systematically analyze the performance characteristics of ODOT's completed rubblization and roll (R/R) projects and to develop guidelines regarding improved specifications. The study was conducted in three parts namely, (1) performance evaluation of Ohios R/R projects, (2) overview of national perspective, and (3) field demonstration of pavement breakers. The performance data obtained in terms of Pavement condition Rating (PCR) was processed to objectively analyze the effectiveness of rubblization on the functional condition of the constructed pavements. The Falling Weight Deflectometer (FWD) data was collected and analyzed to compare the structural conditions of the R/R pavements. Data was collected from other state DOTs to register the performance of their R/R pavements and to learn of their experience with R/R projects. Finally, a 1-day field demonstration of rubblization was conducted to demonstrate the capabilities of pavement breakers operating in Ohio to rubblize under identical conditions. This task was of particular value to verify the compliance of pavement breakers with ODOT specification 320.
