  • Slide 3
  • Pavement Engineering Pavement MaterialsClassification, quality assurance testing (specifications), material design Pavement DesignDesign of Structural layers for New Pavements and Pavement Rehabilitation Assess in-situ pavement material properties and layer thickness Pavement Construction Construction practices of New Pavements and Pavement Rehabilitation including specification development and quality assurance Pavement Management Monitoring Post-construction condition, timing preventive preservation and rehabilitation treatments, and economic analysis of alternatives Pavement ResearchResearch to improve all of the above
  • Slide 4
  • PAVEMENT MANAGEMENT SYSTEM Overview
  • Slide 5
  • DEFINITIONS PAVEMENT MANAGEMENT "Pavement Management is a program for improving the quality and performance of pavements and minimizing costs through good management practices"
  • Slide 6
  • DEFINITIONS PAVEMENT MANAGEMENT SYSTEMS "A Pavement Management System is a set of defined procedures for collecting, analyzing, maintaining, and reporting pavement data, to assist the decision makers in finding optimum strategies for maintaining pavements in serviceable condition over a given period of time for the least cost.
  • Slide 7
  • A Pavement Management System (PMS) is designed to provide objective information and useful data for analysis so that road managers can make more consistent, cost-effective, and defensible decisions related to the preservation of a pavement network. While a PMS cannot make final decisions, it can provide the basis for an informed understanding of the possible consequences of alternative decisions. A PMS does NOT make decisions, Managers DO! PAVEMENT MANAGEMENT SYSTEM Overview
  • Slide 8
  • Pavements deteriorate over time due to traffic/use, environment, and aging Poor road conditions increase vehicle owner costs $325$700 annually (vehicle damage, tire wear, etc.) National average is $333 per motorist totaling $67 billion per year Poor road conditions are a contributing factor in many roadway accidents According to some studies as much as 30% of crashes each year) Good roads cost less if maintained at a reasonable level of service if they receive proper preventative maintenance Importance of Pavement Management Preserving roads in good condition is key to maintaining the health of the States Pavement Network.
