Use of Micro-Surfacing in Highway Pavements
Micro-surfacing is a complex mixture of polymer modified emulsified asphalt cement, crushed mineral aggregate, mineral filler, water, and other additives. When designed and constructed properly, micro-surfacing can be used in thin layers as preventive maintenance and in thick layer to fill ruts as corrective maintenance treatments. This project developed specifications, mixture design procedures, mixture design verification procedures, usage guidelines, and quality assurance requirements for micro-surface treatments applied to highway pavements. The mixture design procedure tests were evlauated in the laboratory and modified as needed. Detailed protocols were developed for each test. Micro-surfacing mixture designs and quality assurance procedures were tested in the field. Quality assurance checklists were developed for use by field personnel. This report presents a method for evaluating cost-effectiveness along with the preliminary results. An approach for completing forensic analysis of early failures was also prepared.
