Microsurfacing as a Preventative Maintenance Program in Texas
並列摘要
Microsurfacing has been shown as an effective pavement preservation tool when applied to the right road, at the right time, for the right distress. This study looks at 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 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; this factor falls under DOT control. However, reliance on contractors for input into proper project selection places the agency in a vulnerable position. A certification course to educate personnel is recommended.
