M1 Motorway between Sydney and Newcastle, Australia was among several road and tunnel pavements where diamond grinding was first introduced. Applied on various road classifications and tunnel pavements, including an 8km section of the M1 Motorway between Sydney and Newcastle, the technique was extended to other Australian states. The earliest application has shown no measurable loss of smoothness or texture after ten years of Motorway traffic.

The two PCCP surface treatment types evaluated in this report, diamond grinding and transverse tining, are compared based on safety, noise, construction cost, service life, rideability, handling, and maintenance requirements.

It is well-established that diamond grinding restores a pavement’s rideability and increases its macrotexture, enhancing skid resistance and reducing the potential for hydroplaning. Tests on pavements in service for almost a decade show diamond ground pavements in Illinois, North Carolina and Oklahoma are performing well.

In this investigation, studies were conducted to understand the effects of innovative textures imprinted into Portland Cement Concrete surfaces on tire-pavement noise generation at the tire-pavement interface.

Experiments were conducted on behalf of the American Concrete Pavement Association by Purdue University's Institute for Safe, Quiet, and Durable Highways to determine the effects of longitudinal diamond grinding and grooving on tire-pavement noise.

Irreversible damage to structures caused by pavement stresses may be reduced if bridge engineers, inspectors, and maintenance workers identify the signs of PG early, and initiate corrective action through the installation of a Pressure Relief Joint (PRJ) in a timely manner.
