This paper presents the development of the Maintenance Technical Advisory Guide (MTAG) for the California Department of Transportation (Caltrans). The MTAG is a technical manual that covers pavement preservation and maintenance principles, materials used in maintenance treatments, treatment selection, crack sealing, chip seals, fog seals, slurry seals, and maintenance overlays. These are the main strategies that are being used by Caltrans for the pavement maintenance program. Guidelines for piloted strategies that utilize microsurfacing and bonded wearing course have also been developed in separate documents. The MTAG was developed for the purpose of assisting maintenance personnel in making better and more informed decisions on selecting and applying maintenance treatments for their highways. It is designed for several levels of use, ranging from general instruction to specific work practice descriptions for the use of maintenance managers, maintenance supervisors, superintendents, and field personnel. Construction personnel and designers may also find use for this publication. Each chapter contains guides for applying the treatments as well as information on troubleshooting problems. A checklist of important issues is appended to each chapter to provide the reader guidance on what to consider in achieving a successful outcome. There has been excellent feedback from the users including maintenance managers, maintenance supervisors, superintendents, and field personnel. Strong and positive feedback also came from the Federal Highway Administration (FHWA) and several states that have used the guides. A training program is being developed that involves class instructions as well as self-directed web-based training.
