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, high-production equipment as well as improved synthetic diamonds for saw blades made DG a more cost competitive option for PCC pavement rehabilitation.
Diamond grinding could save millions of dollars in pavement-rehabilitation costs and free up funding for future freeway improvements. Potential Benefits of Diamond Grinding. In addition to saving money, diamond grinding could result in less highway maintenance. For example, rubberized asphalt has a service life of 10 to 15 years.

The history of continuous diamond grinding for pavement restoration dates back to 1965, when the technique was first used on a 19-year-old section of the San Bernardino Freeway (I-10) in southern California to eliminate excessive faulting (1). Diamond grinding was used as the final step in the CPR program to provide a smooth riding
Diamond grinding is a procedure used to restore or improve pavement ride quality and surface texture. Although diamond grinding has been an available restoration procedure since the 1960's, recent developments and increased experience have made diamond grinding and concrete pavement restoration the best first rehabilitation option for concrete pavements.
Consequently, the pavement will be subjected to reduced dynamic loads which may cause less pavement damage or vice versa. The longitudinal profile and axle load data from the Long-Term Pavement Performance (LTPP) in the SPS-6 experiment were utilized to evaluate the impact of diamond grinding on pavement performance.
The concrete pavement was then diamond ground for superior smoothness, safety and a quiet ride. {plugin[team_member->show()]} "There were several challenges to performing the grinding on the project, due to the busy interchange and having to work around the traffic at the two truck stops and various obstructions at the I-95 exit.

Low noise diamond grinding (LNDG) is referred to in overseas literature as Next Generation Concrete Surface (NGCS) and is the quietest concrete pavement surface texture based on USA test results (Roberts, 2011). The surface texture for LNDG is constructed using conventional diamond grinding equipment and blades with different blade spacing ...

What is Diamond Grinding? A stack of closely spaced diamond tipped saw blades is used to remove a thin surface layer of the pavement while increasing macrotexture Results in smooth, level pavement surface Provides a longitudinal texture with desirable friction and low noise characteristics It is the most common CPP treatment utilized
Concrete diamond grinding removes roadway imperfections caused by construction and/or 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 PC6004EC Highway Grinder brings p roven and patented closed loop control to the field of highway diamond grinding. Custom designed and built at our Nampa, Idaho Facility.

Get more info of silica sand mining process equipment for free.Diamond grinding is a pavement preservation technique that corrects a variety of surface imperfections on both concrete and asphalt pavements.
Diamond grinding rehabs concrete pavement by correcting irregularities and roughness, thus, significantly improving the riding smoothness of the pavement. Our diamond grinding equipment has 240 diamond saw blades that are mounted on a shaft, creating a 4-foot long cutting head that is in the center of the machine.
Diamond grinding of concrete pavement leaves a surface which is often as good as a new pavement. ... The existing asphalt pavement was …
DIAMOND GRINDING . Diamond grinding is the removal of a thin layer of concrete (usually between 0.12 and 0.25 inches) from the pavement surface, using special equipment fitted with a series of closely spaced diamond saw blades. Diamond grinding removes joint faulting and other surface irregularities, thereby restoring a smooth-riding
Diamond Pavement Grinding Trucks. The purpose of diamond grinding is to remove bumps and reprofile the surface of concrete pavements. This improves the riding comfort to motorists and decreases the severity of dynamic or impact loads from heavier vehicles. Impact loads occur as trucks bounce vertically on their suspension system while traveling ...
The truck lane has carried more than 24 million ESALs since rehabilitation in 1984 and more than 43 million ESALs since construction. This 51-year-old pavement is an excellent showcase of the endurance and durability of concrete pavements and effectiveness of CPR with diamond grinding.
Grinding shall be performed using diamond blades mounted on a self-propelled machine designed for grinding and texturing pavement. The grinding equipment shall be at a minimum 35,000 pounds including the grinding head, and of a size that will grind a strip at least 3 feet wide. The effective wheel base of the machine shall be no less than 12 feet.
• Diamond grinding the pavement. • Pavement marking. • Joint and cracksealing. Milling and diamond grinding were able to re-establish the proper drainage profile, drainage surface flow, and provide a better ride quality for trucks and spotter vehicles. The finished surface also allows the owner to begin a maintenance program on the joints ...
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 tyre/pavement noise emission favourably, the relationship among surface texture, concrete composition and noise emission of concrete pavement surfaces has been systematically investigated.
30-year Design: 23 million Trucks •3-in EAC / 8-in RCA –No structural fatigue cracking –Some joint faulting and roughness. –EAC should perform with no problems: good friction, no significant wear. –Diamond grinding should perform with no problems: good friction, low noise.
§ All necessary supplies must be provided to fully operate and graph the smoothness test results on the diamond ground pavement. Contractors doing diamond grinding work use water trucks to provide water to the grinding heads of each grinder to cool the diamond blades. Construction (257.03) The plans will designate the areas to be diamond ground.
Diamond Grinding Project Selection • Structurally sound pavement • Triggers: – Average faulting > 0.08 in (higher for JRCP) – Roughness > 160 to 220 in/mi – Wheelpath wear > 0.25 to 0.40 in – Surface friction below agency standards – Excessive noise levels • …
diamond grinding. For example, a pavement with medium traffic and a roughness IRI (International Roughness Index) value above 3 m/km (190 in/mi) may be beyond the . window of opportunity for cost-effective diamond grinding. In such cases, other . procedures such as an overlay may be a better alternative to restore the pavement's . smooth ride.
Impact loads occur as trucks bounce vertically on their suspension system while traveling across bumps or dips in the road surface. Greater vehicle bounce increases tensile stresses in the slabs and consequently decreases the life of the pavement. Diamond grinding also smoothes out roughness from warped or curled slabs and removes ruts from ...
