Pavement Management Report <br />Page | 12 <br /> <br /> <br /> <br />PAVER MODELING AND ANALYSIS <br />INTRODUCTION <br />PAVER software was utilized in the pavement management for the streets in the City of Lino Lakes. First step in <br />the pavement management process was to develop a pavement deterioration curve for bituminous roadways. <br />Next step was to apply the deterioration curve to all the roadways, and run the 20-year design model. Two main <br />models of interest were budget driven model and target PCI driven model. A curve was also generated when there <br />will not be any maintenance activities done over the years to show the importance of performing maintenance <br />actions to prolong the life of pavements. <br />PCI DETERIORATION MODELS <br />Pavement performance curve, which was based on the Army Corps of Engineer data (Figure IVa), was used to <br />estimate pavement performance for roadways that were not inspected this year. The graph below represents <br />typical pavement deterioration rate, and it may varies depending on the type of maintenance activities done over <br />the period of pavement life. In order to predict pavement performance, all the bituminous roadways were <br />assigned to the following deterioration curve. <br /> <br />Figure IVa.
