Pavement surface texture is defined as the deviation of a pavement surface from a true planar surface, with a texture wavelengt h less than 1.65 ft (0.5 m), and divided into micro-, macro-, and mega-texture (Sandberg, 2002).
Diamond grinding is a concrete repair and pavement restoration technique. It corrects irregularities such as minor pits and divots, faulting, and roughness on concrete pavement. Diamond bits grind the surface of the concrete, leaving a smooth profile that is ideal for thin mill coatings and sealers. Diamond grinding also profiles the concrete and ...
Micromilling. What? 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. ... The pavement surface produced by micro-milling has more ribs which are more closely ...
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 Cement Concrete) pavement ...
Portland Cement Concrete Pavement thickness is 12". In Phase 3 construction, diamond grind Portland Cement Concrete Pavement on northbound Elkton Rd. Use diamond grinding equipment meeting requirements of Section 501.03.2.1.G of the Standard Specifications. Cost of diamond grinding Portland Cement Concrete Pavement is incidental to pay item ...
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 ...

A key factor in the long-term performance of both asphalt and portland cement concrete pavements is initial pavement smoothness. In general, the smoother a pavement is built, the smoother it stays over time, resulting in lower maintenance costs and more comfort and safety for the traveling public. State
WSDOT is investigating the following pavement grinding options to reduce the noise from older concrete pavements. Next Generation Concrete Surface (NGCS) is a new grinding method that has produced the quietest concrete pavements in other states. Conventional diamond grinding (CDG) reduces noise from older concrete pavements.
new technologies for profiling and micro-grinding new concrete pavements (which has greatly improved concrete pavement rideability), the multiple, thinner lifts of the asphalt placement process allow for corrections to be made several times if needed, rather than at the top of a deep section as is the case with concrete.
