Diamond Grinding is a technique for preserving and rehabilitating the concrete pavement surface of a highway. This technique has the potential to reduce costs of rehabilitating our aging infrastructure, while still providing travelers with a smooth, quiet ride.

Diamond grinding is an effective and economical alternative to maintain concrete pavements in good structural condition. (6). The TxDOT Fort Worth district has experimented with the feasibility of adopting diamond grinding as a regular maintenance technique, particularly for functional
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.
Conventional Diamond Grinding for Pavement Preservation Publication Date: 9-30-14 (Rev 5/19/15) SCOPE This standard specifies the procedures for operations of continuous diamond grinding Portland cement concrete or asphalt concrete pavement and roadway surfaces to provide desired surface characteristics such as ride, friction and drainage.
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.
Finding Buried Treasure With Diamond Grinding of a Concrete Pavement After Removal of an Asphalt Overlay. Many times in the past, an agency has covered a sound concrete pavement with an asphalt overlay to improve the ride which may have been a cost-effective solution, but with the recent increase in asphalt prices, the mill-and-overlay option is …
Diamond grinding is a concrete pavement restoration (CPR) technique that provides a smooth riding surface with the desirable friction characteristics on concrete pavements. Diamond grinding can offer numerous advantages over other rehabilitation alternatives. Diamond grinding costs substantially less than an overlay (3), and for many
Diamond grinding of Portland cement concrete pavements and micro-milling of bituminous asphalt pavements are superficially similar in concept, but that's just about the only thing they have in common. Diamond grinding of aging Portland cement concrete (PCC) pavements renews the pavement's skid-resistance, and provides a smoother-riding ...
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 …
Diamond-Grinding Machine Verify that the diamond-grinding machine meets requirements of the contract documents for weight, horsepower, blade configuration, and effective wheel base. Verify that the equipment has a positive means of vacuuming the grinding residue from the pavement surface, leaving the surface in a clean, near-dry condition.

Section 431—Grind Concrete Pavement 431.1 General Description This work includes grinding existing Portland cement concrete pavement to eliminate joint faulting or to restore proper drainage and riding characteristics to the pavement surface. Perform the work according to these Specifications and the Plans. 431.1.01 Definitions
Diamond grinding is a concrete pavement rehabilitation technique that corrects irregularities such as faulting and roughness on concrete pavements. Diamond grinding should be used in conjunction with other concrete pavement rehabilitation techniques. Diamond grinding restores rideability by removing surface irregularities caused by construction ...
As Britain's concrete roads increasingly suffer the effects of ageing, Highways England has set aside £400m for a renewals and repair programme in the In this Guide to LDG, Richard Powell from Roadgrip Ltd explains the benefits of longitudinal diamond grinding (LDG) and the impressive results it's already achieving on UK roads.
Diamond Grinding Of Concrete Pavements. Previous studies by others had proposed that corrugating porous surfaces would improve their acoustic properties.To investigate the validity of that lemma, a concrete test section built in 2008 specifically as a 4 inch thick pervious overlay on an 8 inch thick concrete pavement in the low volume test track of the mnroad research facility …
diamond grinding of older concrete pavements, particularly in urban areas, are set out in Roads and Maritime specification M229. A list of diamond grinding and associated road specifications is listed in Table 1 (Section 4.4). Specification R93 has been prepared for projects involving construction of slipformed concrete
What: Diamond grinding uses closely-spaced diamond saw blades to remove a thin layer at the surface of hardened portland cement Concrete Pavements. The blade assembly is run at a predetermined level (typically 3/16 to 1/4 ") across the pavement surface, producing saw cut grooves. The uncut concrete between each saw cut breaks off, leaving a macroscopically […]
Diamond Grinding of Concrete Pavement R93 . Ed 1 / Rev 2 3 . SFCP: Steel fibre reinforced concrete pavement (Base) 2 M. ATERIALS. 2.1 G. ENERAL. Materials required for carrying out the Works in accordance with this Specification include the following:
• Diamond grinding –Removal of thin layer of concrete surface to restore smoothness and friction • Diamond grooving –Creation of channels in concrete pavements to reduce hydroplaning potential 9‐3 Surface Comparison Diamond Grinding Diamond Grooving 9‐4 Other Surface Textures
Diamond grinding is a concrete pavement restoration process that renews a worn or slightly irregular surface. Diamond grinding can potentially remove or reduce some pavement deficiencies such as joint faults resulting from minor pavement settlement, worn pavement from wheel rutting, warped slabs, and a rough surface texture.
Diamond grinding is one of the most cost effective concrete pavement restoration (CPR) techniques. It consists of "grinding" 3/16 to 1/4 inch (5 to 7 mm) of the surface of jointed plain concrete pavement (JPCP) using closely spaced diamond saw blades. The result is a level, smooth, and generally quieter riding surface.
