Pavement Accelerated Repair Implementation Strategy Program (Finalist)

The City of Redlands has implemented the Pavement Accelerated Repair Implementation Strategy (PARIS) Program to access and resurface two-thirds of city streets over a five year period. The scope of street repairs will include pulverization, grind and overlay and slurry seal. Striping, curb and gutter, and cross gutters are replaced or repaired where affected by paving work. It total, the program will repair 378 lane miles of local streets, 129 lane miles of minor streets, and 133 lane miles of major streets. The current phase, contracted at $8,739,532.00, includes funding from I-Bank, Measure I and Local Transportation dollars. When complete, PARIS will raise the City’s pavement condition index to approximately 80 placing Redlands among the top cities in California by the end of project-year five. The PARIS project is built on the City’s innovative Pavement Management Program (PMP) under which the physical condition of City streets are evaluated and the remaining street life cycle determined. The PMP prioritizes streets for repair based on metrics including: street PCI, average daily traffic, truck routes, vicinity to schools, and population density. As part of the PMP staff utilized eRoad Pavement technology, or “eRoad”, an automated pavement evaluation system to create a database of the current inventory of City street conditions, treatment options, and cost estimates for each treatment available. This methodology takes advantage of an in-depth analysis provided by the eRoad system and use of advanced GIS technologies. The result is a “big-picture” approach that graphically shows streets that warrant treatment based on function, location, and the condition of street surface. The PARIS program has allowed the City to save money, time, and be environmentally friendly through utilization of pulverization where applicable. Pulverization is a process that grinds up existing street surfaces and blends the output to create a new paving mix – all done on-site. Pulverizing existing layers has many benefits over excavation and re-paving: • Saves money: old base layers do not have to be excavated (they are mixed in during the process) and new materials do not need to be hauled. • Faster: the reconstruction process goes much more quickly because the work is all done on-site. • Environmentally friendly: because new base materials do not need to be imported and all existing material is recycled on location (with excess diverted for other uses), pulverization reduces transportation and materials costs.
