2021-8-15 · 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.
3.6. DIAMOND GRINDING Grinding shall be performed in the longitudinal direction so grinding begins and ends at lines normal to the pavement centerline. The allowable overlap between passes shall be 0 to 2 inches
2019-3-29 · Diamond Grinding. Begin and end diamond grinding at lines normal to the pavement centerline. Grind the pavement longitudinally such that at least 95% of the pavement surface is diamond ground and the pavement is in the same plane across a joint or crack when measured with a 36 inch (minimum) straightedge.
2018-12-18 · dates for diamond grinding are those in struc-turally sound condition with primarily surface defects—slight to moderate rutting, shallow top-down cracking (up to ¼-inch deep) or oxi-dation. In addition to grinding, grooving—cut-ting narrow, discrete grooves into the pavement surface—is an asphalt pavement preservation
2018-12-18 · 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.
2017-4-18 · 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.

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 between the existing pavement and the overlay.
2018-6-19 · {Diamond grinding was first used in California in 1965 on a 19-year old section of I-10 to eliminate significant faulting (Neal and Woodstrom 1976). {In 1983, CPR was conducted on this same pavement section including the use of pavement section, including the use of additional grinding to restore the rideability and skid resistance of the surface.
2017-9-21 · continuously reinforced concrete pavement (CRCP), and steel fibre reinforced concrete pavement (SFCP). A typical grinding machine used in Australia is shown inFigure 1 . The grinding drum is between the front pivoting bogey wheels and rear axles, with the engine and water tank at the rear of the vehicle.
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
2018-4-30 · sections. Grind all areas represented by individual points having deviations in excess of 0.3 inch in 25 feet or less pavement length, until such points do not exceed 0.3 inch. After removing all individual deviations in excess of 0.3 inch in 25 feet, perform additional grinding as necessary to reduce the Profile Index to the specified ...
2022-2-9 · Diamond grinding on the Loop 202 (Santan Freeway) In early 2020, ADOT used diamond grinding to replace older rubberized asphalt overlays in three areas along the Loop 202. In those locations, the rubberized asphalt pavement had been in place well beyond its planned service life, resulting in rough highway surface conditions.

Concrete Pavement Preservation Guide (Smith et al. 2014)
A. Scarify 6 inches below new pavement section, bring to optimum moisture content, and compacted to a relative dry density of 95%. 3.2 AGGREGATE BASE COURSE A. Base material shall be furnished, placed and compacted for asphalt concrete ... J. Payment for grinding asphalt pavement shall be considered to be included in the
Overlays (either structural or non-structural) make up a large portion of the roadway paving done today.The degree of surface preparation for an overlay is dependent on the condition and type of the existing pavement. Generally, the existing pavement should be structurally sound, level, clean and capable of bonding to the overlay.
2020-8-12 · Pavement grinding to begin Thursday. Beginning Thursday, August 13 th, the contractor will begin to grind the existing pavement. Some streets will have all of the existing asphalt pavement removed and others will have approximately three inches of existing asphalt pavement removed.

2021-1-27 · 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.
2015-12-21 · For cuts in pavement that have been constructed or overlaid within 3 to 5 years, grind a minimum of 1-1/2 inches from lane line to lane line or edge of pavement/lip of gutter and overlay with asphalt concrete. The 1-1/2 inch grind depth is a minimum. The grinding must produce a stable surface for new pavement material. A seal coat is not required.
