Pavement sawing contractor Rick Younger invented a patented device for grooving and grinding concrete pavement. It consists of replaceable straps mounted on a rotating drum with a metal inner core. A hard rubber sleeve covering the drum absorbs shocks, jarring and vibration. The straps are mounted on an outer metal sleeve that covers the rubber.
Sawing grooves into pavements greatly reduces wet weather skidding accidents on roads and airports. During the past 15 years more than 5 million square yards of highway pavements have been grooved and accident records verify that grooving creates safer highways.
Diamond grinding is a pavement preservation technique that corrects a variety of surface imperfections on both concrete and asphalt concrete pavements. Most often utilized on concrete pavement, diamond grinding is typically performed in conjunction with other concrete pavement preservation CPP techniques such as road slab stabilization, full and partialdepth repair, dowel bar retrofit
In June of 2013, the tender for Diamond Grooving of concrete pavements on Highway 115 was issued. The tender opening was August of 2013. The tender also included extensive resealing of concrete joints. The diamond grinding technique has been used on Ontario highways before, but grooving was a new concept for MTO.
Grooving has significantly reduced accidents on pavements that exhibit a low coefficient of friction or high accident rate. Signs installed on some sections of highway indicate that the highway surface has been grooved when it has, in fact, been cold milled by equipment using carbidetipped teeth to cut the surface.
Concrete diamond grinding removes roadway imperfections caused by construction andor heavy usage. The immediate result is an improvement in pavement smoothness, surface texture, skid resistance, safety, and noise reduction. This service can also be applied to asphalt pavement. Advantages of diamond grinding over other rehabilitation techniques
The texture is usually produced in two passes using diamondtipped saw blades mounted on conventional diamond grinding and grooving equipment. After transverse grooves are removed, pavement is flushground using 18inchwide blades with 0.035inch spacers.

Grooving production is contingent on many factors including type of material to be grooved asphalt or concrete, the type of aggregate, dimensions of the runway, slurry disposal requirements, etc. but a reasonable expectation is from 400 square yards 330 square meters to 700 square yards 585 square meters per actual production hour in asphalt and about 60 of that in concrete for non
RTI Research Project 5904601 is studying the longterm benefits of grooving pavement utilizing diamond grinding.
