• The City of Robbinsdale (with an organized system) set aside $150,000 from solid waste fees for roads in 2008. The presentation did not specify how many miles of roads the total cost figures are intended to maintain. Foth, MCPA, 2009 (16) Also in 2009, Foth Infrastructure & Environment produced a report for the Minnesota Pollution Control Agency regarding waste collection service agreements. The report cited the University of Michigan (1992) as saying "fatigue damage to rigid and flexible pavements is most directly determined by maximum axle loads and pavement thickness." The report also cites the R3 (2008) report and the truck / passenger car equivalent concepts, discussed in that report. The Foth report also cites the University of Michigan's claim that starting and stopping of garbage trucks can increase damage by 50 to 100% (17). The conclusions of the report, as they relate to pavement damage, include the following. • Main causes for deterioration include traffic volume, type of traffic, and environmental factors (water, temperature, sun, pollutants). • A properly designed bituminous surface should be able to handle the traffic loading over its design life including heavy truck loadings. • Environmental factors are generally responsible for the majority of pavement wear and deterioration. The Foth report also provided comments by municipalities regarding their perceptions of the impacts of heavy trucks (and garbage trucks in particular) on their streets. These are summarized below. • Bloomington The City engineer put together a memo that references MnDOT studies. This memo also outlines the Bloomington road weight restrictions, comparisons of heavy traffic, and costs for repair. In addition, the City has photos of road wear in cul-de-sacs where garbage trucks are the only trucks entering (school buses and other heavy trucks do not enter cul-de-sacs). • Lakeville We do not have a position on how collection vehicles impact our roads. We're sure they do, but it has not recently been addressed or studied. • Prior Lake We know there are impacts but we have no studies. • Rosemount There have been some comments from the public works department but mostly there have been comments from elected officials. 10
