This paper highlights some of the events that took place on Ohio Department of Transportation (ODOT) construction project 614-05 on US Route 23 in southern Ohio during the 2006/2007 construction season. Diamond grinding on this project significantly improved rideability through the bridge encounter. This case study demonstrated that the grinding simulation in ProVAL is a useful tool at predicting rideability after grinding.

This report describes the innovative grinding conducted on cells 7, 8, 9, and 37 at the MnROAD research facility of the Minnesota Department of Transportation. The three types of diamond grinding studied include a conventional method, the “innovative grind” (flush grind and groove) and the “ultimate grind” (flush grind and groove, with wider spacing between grooves than the innovative grind). The report describes the construction efforts followed by the initial testing, and the plans for long-term observation, monitoring, and surface characteristics testing.

This report addresses work conducted under Part 2 of the program. This is the most comprehensive inventory of concrete pavement surface textures ever compiled. The inventory includes transverse and longitudinal tining, diamond grinding, various drag textures, diamond grooving, exposed aggregate, shot peening, cold milling, and some asphalt pavements and surface treatments.

Seal/No Seal (SNS) Tech Brief: Joint Movement Estimator for Designing Transverse Joint Seal Installations. Sealing of concrete pavements began approximately a century ago when full-depth repair (FDR) gaps were left between slabs to allow for expansion and to control cracking. The gaps were commonly filled with asphalt, tar, pitch, or boards.

Seal/No Seal (SNS) Tech Brief: Joint Slap Evaluation and Prevention. An often overlooked aspect of quiet pavement design is the impact of transverse joints on the overall tire-pavement noise level. This aspect is important both for the design of new pavements and the rehabilitation of existing pavements.

FHWA ACPT products program tech brief describes both conventional methods and an alternative method for making full-depth repairs (FDR) in continuously reinforced concrete pavements. The alternative method, which does not utilize continuous longitudinal reinforcement in the repair area, is suitable for repairing a single lane (or two of three adjacent lanes), and results in repair areas that have performed well after several years.
