IMS Infrastructure Management Services Arden Hills Report P a g e | 4 <br />3.0 THE PAVEMENT MANAGEMENT PROCESS <br />3.1 IMS PAVEMENT MANAGEMENT PROCESS OVERVIEW <br />As shown in Figure 4 below, the IMS Laser Road Surface Tester was mobilized to Arden Hills to conduct <br />an objective survey and to collect pavement imagery, roadway geometry, longitudinal and transverse <br />profile, and surface distress data. <br />The collected pavement imagery, and surface distress data were analyzed following the ASTM D6433 <br />Standard Practice for Roads and Parking Lots Pavement Condition Index Surveys for assessment of <br />Pavement Condition Index (PCI). These measurements of pavement quality formed an overall 0 to 100 PCI <br />score, with 100 representing the best and 0 representing the worst pavement conditions. The pavement <br />longitudinal profile data was also analyzed based on ASTM E1926 to assess its roughness through <br />determination of the International Roughness Index (IRI). <br />To ensure the success of the implemented pavement management program, a pavement assessment and <br />analysis should be completed every few years to update the budget models and rehabilitation plans. <br /> <br /> <br />Figure 4 - Laser Road Surface Tester (RST) <br /> <br /> <br /> <br />
