Diamond grinding should be applied to the portion of the pavement where restoration is needed. 4 12 16 A highway agency can require grinding only on the truck lanes of a fourlane divided highway presenting a significant cost advantage.
Truck Mounted Grinders provide the ultimate in production capabitity. Mounted on heavy duty and medium duty diesel truck chassis these units are capable of high speed automated pavement marking removal automated grooving automated taper slot cutting as well as simple line removal.
measurements at 10 m 33 ft indicate that there is about 3 dB noise reduction due to the diamond grinding for all vehicles including heavy trucks. When heavy trucks are excluded the noise reduction is about 4 dB.
DSI started as a diamond grinding contractor in 1989. Our reputation is solid in the grinding industry as a leader and innovator.
Diamond grinding DG removes a thin layer at the surface of hardened PCC pavement using closely spaced diamond blades. DG used to be an expensive operation however new highproduction equipment as well as improved synthetic diamonds for saw blades made DG a more cost competitive option for PCC pavement rehabilitation.
Diamond grinding of pavement Last updated August 17 2019. Diamond grinding is a pavement preservation technique that corrects a variety of surface imperfections on both concrete and asphalt pavements.

Comprehensive Truck Size and Weight Limits Study Pavement Comparative Analysis Technical Report Chapter 4 Scenario Impacts. 2009 to 2013 for concrete diamond grinding. Recent asphalt overlay construction data was gathered from the National Center on Asphalt Technology and State asphalt pavement association representatives. The total cost.
DIAMOND GRINDING PAVEMENT TREATMENT. Closely spaced diamond blades remove a thin layer of roadway surface about 188 of an inch. How Diamond Grinding Works The road surface has a consistent smooth texture. Up close the diamondground road surface looks similar to corduroy fabric.
Diamond Grinding Project Selection Structurally sound pavement Triggers Average faulting gt 0.08 in higher for JRCP Roughness gt 160 to 220 inmi Wheelpath wear gt 0.25 to 0.
4 made. Diamond grinding and grooving is one of the techniques that can be used to improve 5 pavement smoothness while increasing the drivers safety by improving the frictional properties 6 of the riding surface. 7 This paper evaluates the effect of diamond grinding and grooving on various surface 8 characteristics of concrete pavements.
Diamond Surface Inc. sets the standard for excellence in Heavy Highway Construction of diamond grinding rumble stripping and concrete pavement restoration. Members of International Grooving and Grinding Association Concrete paving Association and American Concrete Paving Association.
Jul 02 2014nbsp018332Diamond grooving and grinding is a concrete pavement preservation technique that corrects a variety of surface imperfections on concrete pavements and may be used in.
As grinding progresses slurry is vacuumed and pumped into a tanker. Grinding is often utilized for correction in longitudinal directions on asphalt concrete pavements and bridge decks. Grooving involves multiple diamond blades moving in a transverse direction on a bridge deck to produce a mechanically tined surface for skid resistance and.
Dec 28 2000nbsp018332Diamond grinding on I20880 has areas of heavy cuts due to additional pavement wear from truck tire chains. Typically diamond grinding removes less than 14 in. average depth of the existing concrete surface. Prior to the I20880 project Pavement Specialists also ground 100000 sq yd of pavement on I2088 near El Centro.
Diamond Grinding Pavement Interactive. Because the grinding head is cooled with water a byproduct of diamond grinding is a slurry of ground PCC particles and water. Most of this slurry is picked up by vacuums within the grinding machine and either deposited along the highway shoulder in some rural areas or collected in trucks for disposal.
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.
Dec 28 2000nbsp018332The truck lane has carried more than 24 million ESALs since rehabilitation in 1984 and more than 43 million ESALs since construction. This 51yearold pavement is an excellent showcase of the endurance and durability of concrete pavements and effectiveness of CPR with diamond grinding.
In Germany diamond grinding is frequently used to improve the evenness and skid resistance of concrete pavement surfaces. Since diamond grinding has been observed to affect tyrepavement noise emission favourably the relationship among surface texture concrete composition and noise emission of concrete pavement surfaces has been systematically investigated.
Truck Mounted Grinders provide the ultimate in production capabitity. Mounted on heavy duty and medium duty diesel truck chassis these units are capable of high speed automated pavement marking removal automated grooving automated taper slot cutting as well as simple line removal.
A water truck follows in close proximity delivering cooling for the diamond blades while minimizing any dust hazards. The onboard vacuum system with diaphragm slurry pump collects the slurry and grinding tailings and discharges them to a separate collection tanker or other collection resource.
