Book Description
The Superpave hot mix asphalt design, which was developed under the Strategic Highway Research Program (SHRP), has been used in the following seven initial projects in Ohio: HAN-075-22.42, OTT-002-16.60, COS-036-27.53, CLE-032-0648, LAW/JAC-093-26.44/0.00, RIC-30-6.01, and ATH-033-05.48. The Ohio Department of Transportation (ODOT) intended to use data from these initial projects to relate the engineering characteristics of the asphalt mixes with future performance of the pavements, and to assure that the experiences of all involved parties are taken into consideration. To get such insight about Superpave mixes, ODOT formed a Superpave evaluation committee with representatives from ODOT, Federal Highway Administration (FHWA), Asphalt Institute, Flexible Pavement, Inc. (FPI), and academia. This research study was undertaken to collect in a uniform, organized manner the available data from ODOT and asphalt paving contractors on the initial seven Superpave paving projects. The collected data addresses various issues relating to the mix design process, construction practices and pavement performance, and should allow future pavement design process and construction technology to take advantage of previous experience.

Book Description
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, (i) performance evaluation of Ohio's R/R projects, (ii) overview of national perspective, and (iii) 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.
