Managing Tomorrow’s Resources Today ZeeLaura Page May 8, 2024 Page 4 of 8 Overview Road maintenance is based on deterioration. While roads will deteriorate if simply left unused, most deterioration is associated with use. The damage caused by vehicles increases much more than proportionately with size and weight. Hence, maintenance costs are greater for trips made by heavy vehicles. A single, large truck can cause as much damage as thousands of automobiles, and a truck’s configuration can affect the amount of damage as well. If the load is spread over more axles, allowing for less weight on each wheel, then damage is reduced.1 Refuse Vehicles are generally some of the heaviest vehicles regularly operating on City streets. Accordingly, these vehicles contribute significantly to the cost of maintaining those streets. Generally speaking, the City’s streets are in good shape (with and Average PCI of 67); however, assuring adequate future funding for an effective pavement management program is one of the most financially prudent steps the City can take. Rapid deterioration of pavement typically occurs after roadways drop to a PCI score of 60 or lower;2 therefore, assuring adequate funding for an effective pavement management program for the City’s streets is critical. Delays in preventative maintenance increase the quantity and severity of pavement defects, and result in higher costs during pavement life. Consequently, using only a routine and reactive approach will considerably increase the life cycle costs of the pavement. 3 Background Pleasanton Garbage Service provides collection services for solid waste, recycling, and organics exclusively for residential and commercial customers in the City. Residential solid waste, recycling, and organics are collected in an automated, side-loading, vehicles that collects materials from all customers on each side of each street in a single pass. Commercial collection service is provided in varying frequencies to customers by front-loading vehicles. To be conservative in our estimates, we have assumed these vehicles service the average commercial customer account 1 time per week. Approach Our analysis is based on the City ’s projected Average Annual Expenditures and allocates the Average Annual Expenditures attributed to the impacts of Refuse Vehicles on the City ’s streets. The basis for allocating the Average Annual Expenditures is made by calculating the Equivalent Single Axle Load (ESAL) of each type of vehicle traveling on the City ’s streets, as described below. The weight and loading of Refuse Vehicles impose a particular, specific, and quantifiable impact on streets. The analysis is based on the fact that the City ’s streets are designed to handle a certain amount of vehicle 1 Rufolo, Cost-Based Road Taxation, Cascade Policy Institute, Policy Perspective #5, November 1995. 2 Metropolitan Transportation Commission, “Current Issues in Pavement Maintenance and Management.” July 2002. 3 A Pavement Preventative Maintenance Program; Larry Galehouse, P.E., L.S.; Michigan Department of Transportation.
