Pavement Management Report P a g e | 3 Compared to 2021 when a similar report was issued, the average PCI in the City has changed from 73.6 to 75.5. Table 1 shows how the area weighted average PCI in Lino Lakes has changed over the past five years. These records show the maintenance and construction performed by the City have maintained the network in relatively stable condition. Additionally, the last two years have seen the PCI increase, which is also due to the City adding new roads to the system. Table 2 shows the mileage of pavement in each category. Table 1.

Corrective maintenance includes crack sealing and patching. These types of maintenance should be conducted as soon as cracks or distresses surface to reduce the infiltration of water and incompressible materials through the cracks. These fixes are recommended on roads in the upper range of the Adequate category because those roads should not need any major repairs. Preventive maintenance includes surface treatment such as crack sealing, fog sealing, and rejuvenating. These maintenance activities should be performed while the pavement is still in good condition. As roads deteriorate, these cost-effective maintenance strategies become ineffective and more expensive fixes are required. With proper preventative maintenance techniques, the life of an average paved road increases from 20 years to 50 years. Each type of preventive maintenance serves its own function, and project selection depends on the type and severity of distresses observed in the road. A more detailed evaluation of each road is required to accurately determine the proper maintenance strategy. 2022 Inspection 2021 Inspection 2020 Inspection 2019 Inspection 2018 Inspection Adequate 70.01-100.00 69.8%68.2%65.0%66.5%63.9% Marginal 40.01-70.00 23.0%21.4%20.3%19.8%22.2% Problem 0.00-40.00 7.2%10.4%14.6%13.7%13.9% 75.5 73.6 71.0 71.0 71.4 Historical Pavement Conditions Condition PCI Range Percent of Roadway Network by Area Weighted Average PCI
