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 noise, and improved friction.

In grinding, leveling, and re-texturing PCC pavements, pavement waste can be removed and collected in one step, and hauled to a concrete batching plant capable of receiving and recycling used material. PCC grinding generates volumes of very fine particles that are controlled by using a wet-vacuum system.
Diamond grinding is a widely-used rehabilitation technique usually referred to as resurfacing of Portland cement concrete (PCC) pavement. As a maintenance operation, diamond grinding can provide a smooth PCC surface with enhanced texture and skid resistance and reduced road noise.
For. rehabbed PCC pavements, the department is planning to lengthen. its 10-plus year extension of surface pavement life philosophy. to 20 to 25 years before major rehabilitation becomes necessary. Field practice. Taking part in four of the diamond-. grinding projects, totaling more than $15 million in contracts.

Diamond grinding (Figure 1) refers to a process where gang-mounted diamond saw blades (Figures 2 and 3) are used to shave off a thin, 1.5 – 19 mm (0.06 – 0.75 inch) top layer of an existing PCC surface in order to restore smoothness and friction characteristics. Most often, it is used to restore roadway friction or remove roughness caused by faulting, studded tire wear, …

covers those activities and maintenance treatments for concrete pavements (PCC). These include the following: • Temporary patching of PCC pavements • Permanent patching of PCC Pavements • Shoulder repairing • Crack and joint sealing and contracted crack and joint sealing • Grinding • Mud jacking Purpose
What is Diamond Grinding? Removal of thin surface layer of hardened PCC using closely spaced diamond saw blades Results in smooth, level pavement surface Provides a longitudinal texture with desirable friction and low noise characteristics Frequently performed in conjunction with other CPP techniques, such as full-depth repair,

No payment is made for any reporting segment having an average IRI greater than in/mi after diamond grinding if Diamond Grinding Smoothness Quality 140 Adjustment is included in the contract documents. Smoothness Quality Adjustment - Quality Units of Smoothness Quality Adjustment are a fixed ...
PCC pavement grinding is an operation used to preserve pavement ride quality/friction, rehabilitate pavements, or facilitate construction widening by removing or reducing undulations in the pavement from curling within a slab or step offs between slabs (a.k.a. faulting).

Section 2532. Pavement Surface Repair (Diamond Grinding) 2532.01 description.. A. Use a diamond grinder to grind an existing PCC pavement surface, used as traffic surface, for profile improvement. Perform grinding and texturing at the locations shown in the contract documents.
The purpose of the research was to accurately determine the types and extent of problems created by spot diamond grinding on concrete pavements. Diamond grinding was first used in California, in 1965 on a 19-year-old section of I-10, to eliminate significant faulting. Since this first application, pavement grinding has grown to become a major element of PCC (Portland …

Diamond Grinding – PCC Pavements. Although typically used for rigid pavement surface restoration, diamond grinding can be used to eliminate relatively small surface distortions in existing rigid pavement prior to flexible or rigid overlays. Because it roughens the existing rigid pavement surface, diamond grinding also improves the bond ...
