Opening criteria for accelerated paving techniques

Abstract

Fast track paving or accelerated pavement design is the rapid replacement of portland cement concrete pavement, allowing for the reopening to traffic under specific time requirements. The purpose of this research is to develop opening criteria for accelerated paving and implementing these criteria into a set of guidelines for fast track paving. This report is broken into three specific sections; review of practice, an analysis of field and lab research, and finally design guidelines for the opening criteria for accelerated paving techniques. A review of practice was developed to update the reader on the current "state of the art". This review outlines contruction techniques, fast track mix design, pavement design, and joint design. The analysis of field and lab research provides a synopsis of the experimentation used to develop design guidelines for opening criteria. This section includes crack surveys, coring tests, FWD testing, maturity testing, penetration testing and consistency testing. The design guidelines for early opening criteria provides guidelines for use in intersection design. The guideline outlines requirements for design, design of concrete pavement materials, mixture design, construction considerations, and requirements for opening criteria. This document will update the reader on the subject of fast track paving and the methods used to research it. Finally, with a design guidelines the reader will be able to apply the methods of analysis described in the field and lab testing section to create better pavements more efficiently.
