  • Abstract:
    Microsurfacing is a unique pavement preservation tool in the arsenal of maintenance agencies. It is known to ; perform well when applied to the right pavement at the right time for the right distress. In order to ensure ; microsurfacing performs well, an agency must know what constitutes the right road, right time and right ; distress. Texas uses microsurfacing and wishes to answer these questions as well as uncover other factors ; leading to successful use of this treatment. ; This report describes the current state of practice of microsurfacing in Texas and compares it to best ; practices extracted from existing literature. A survey of DOT personnel, contractors and emulsion suppliers ; in Texas provides insight into the most crucial factors contributing to the success or failure of a ; microsurfacing. From the results of the survey, literature reviews, case studies and site visits, the research ; team analyzed material selection and mix design methods, construction practices, equipment practices and ; performance measures for microsurfacings. It was concluded that project selection is the most important ; contributor to a successful microsurfacing followed by construction practices. Reliance on contractors for ; input into proper project selection places the agency in a vulnerable position. A certification course to ; educate personnel is recommended.
