28 Jun Diamond Grinding for Local Roads Posted on Jun 28 2020 Diamond grinding is the removal of a thin layer of hardened concrete pavement surface using a selfpropelled machine outfitted with a series of closely spaced diamond saw blades mounted on a rotating shaft.
Grinding shall be done using diamond blades mounted on a selfpropelled machine designed for grinding and texturing pavement. The equipment shall be a minimum 35,000 pounds, including 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.
#0183;#32;This Technical Bulletin recommends procedures for selecting, designing, and construction of diamond grinding in portland cement concrete pavements. Diamond grinding consists of removing surface irregularities from concrete pavements that are often caused by faulting, curling, and warping of the slabs. The main benefits of properly using this technique include smoother ride, reduced road

Diamond grinding consists of removing surface irregularities from concrete pavements that are often caused by faulting, curling, and warping of the slabs. The main benefits of properly using this technique include smoother ride, reduced road noise, and improved friction. Diamond grinding can be used as a standalone rehabilitation technique.
Pavement Distresses that Require Diamond Grinding (DG) As stated above, DG can be a useful tool to correct functional distresses caused by pavement surface defects, such as, noise, roughness, and skid resistance. When noise has become an issue, research data
Diamond sawcut textures (grooving and grinding) is an additional technique for Pavement Engineers. It is a time proven, cost effective means of providing consistently smooth, quiet and safe textures at a less cost of asphalt overlays. REFERENCES.

Deeper diamond grinding will expose the coarse aggregate in the concrete pavement Softer coarse aggregates that are exposed may polish and result in lower skid numbers The department developed special specifications for diamond grinding.

Diamond grinding is a concrete pavement restoration technique that corrects irregularities such as faulting and roughness on concrete pavements. Diamond grinding should be used in conjunction with other Concrete Pavement Rehabilitation (CPR) techniques. A full CPR job can restore structural and functional capacity of a pavement to acceptable levels

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 techniques such as road slab stabilization, full and partialdepth repair, dowel bar retrofit, cross stitching longitudinal
Diamond grinding addresses serviceability problems but not their root cause. For example, diamond grinding can substantially reduce the roughness on a faulted rigid pavement, but it will not address the cause of faulting, nor will it prevent roughness in
