PAVEMENT MANAGEMENT SYSTEMOverview
DEFINITIONSPAVEMENT MANAGEMENT"Pavement Management is a program for improvingthe quality and performance of pavements andminimizing costs through good managementpractices"
DEFINITIONSPAVEMENT MANAGEMENT SYSTEMS"A Pavement Management System is a set of definedprocedures for collecting, analyzing, maintaining, andreporting pavement data, to assist the decisionmakers in finding optimum strategies for maintainingpavements in serviceable condition over a givenperiod of time for the least cost."
PAVEMENT MANAGEMENT SYSTEMOverviewA Pavement Management System (PMS) is designed toprovide objective information and useful data foranalysis so that road managers can make moreconsistent, cost-effective, and defensible decisionsrelated to the preservation of a pavement network.While a PMS cannot make final decisions, it can providethe basis for an informed understanding of the possibleconsequences of alternative decisions.A PMS does NOT make decisions, Managers DO!

ANALYSESECONOMIC ANALYSESMulti-Year Prioritization (MYP)A method of allocating limited resources in anefficient and cost-effective way over a multi-yearperiod (2-10 year’s needs), through an evaluation oflong-term impacts.A PMS process or tool used to objectivelyidentify the best combination of projects over amulti-year program.
ANALYSESECONOMIC ANALYSESMulti-Year Prioritization (MYP)Prioritization techniques use mathematical modeling toolsto achieve the best combination of projects over thespecified analysis period: Pavement performance Models predict futurecondition and suggest timing of needed rehab Projects are identified with need for PM, Minor Rehab,Major Rehab or Reconstruction The most effective timing for the applying theappropriate treatment are identified
ANALYSESECONOMIC ANALYSESBenefits Provided By MYP Forecast future conditionsAnalyze timing optionsEvaluate effectiveness of alternative strategyPerform economic analysesUse of objective measures for prioritizing needsProject future budgetsPredict the impact of each combination ofprojects on the network over the given analysisperiod
