Concrete Pavement Rehabilitation-Guide for Diamond Grinding

摘要

This Technical Bulletin recommends procedures for selecting, designing, andconstruction of diamond 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. Diamond grinding can be used as a stand-alone rehabilitation technique. However, FHWA recommends its use as part of a comprehensive Concrete Pavement Rehabilitation (CPR) program. Information regarding cost and performance is also included in this document.This document has been prepared in part with information collected under the sponsorship of FHWAs Special Project 205, Quality Concrete Pavement Rehabilitation. Other documents to provide similar guidance in other CPR techniques will follow.
