Rubberized asphalt is temperature sensi ve, so paving in the Valley can occur only during spring and fall. Rubberized asphalt paving also may require freeway closures, while diamond grinding can ...

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.

Conventional diamond grinding (CDG) reduces noise from older concrete pavements. Next Generation Concrete Surface. King County installed a section of NGCS texturing on both directions of Avondale Road between NE 144th Place and NE 151st Street. The chart below shows the noise level of the concrete before grinding and up to 13 months after grinding.

Dec 28, 2000 The process is an important element of concrete pavement restoration (CPR) and is used to restore or improve pavement rideability and enhance the inherent friction characteristics of concrete pavements. Diamond grinding was first used in 1965 to eliminate excessive faulting on a 19-year-old section of I-10 in southern California.

Jul 11, 2011 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 ...

Oct 01, 2016 1. Introduction. Diamond grinding is a widely accepted practice to remove bumps and rectify surface defects on concrete pavements. It has been effectively used as part of concrete pavement restoration (CPR) since 1965 (ACPA, 2006, Caltrans, 2005).A study surveyed a total of 76 diamond-ground concrete pavements from 9 states and found that the average life of a typical diamond …

Asphalt Grinding . Asphalt rubble that was previously typically disposed of at landfills, can now be processed on site by a milling machine into particle sizes that allow asphalt millings to be reused in hot mix pavement or can be used on your job site in areas where the soils are sub-standard or are unstable.

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. Diamond grinding provided a much improved, smooth concrete driving …

This standard specifies the procedures for operations of continuous diamond grinding asphalt pavement to eliminate surface defects such as rutting, roughness and surface deterioration as well as provide desired surface characteristics such as smooth ride, improved friction and drainage. This standard does not apply to corrective bump grinding.

Apr 18, 2017 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.

Micro-milling is the removal of a small thickness (1 inch or less) of existing asphalt concrete prior to placing a surface treatment. The difference between cold milling and micro-milling is the texture left on the existing pavement. Micro-milling provides for a smoother surface than cold milling and is typically used before a slurry seal or ...
