The following are some of the conclusions reported, relating <br />to the impacts of heavy trucks on roads. <br />• Impact on roads is variable, based on street type, and relative amount of garbage truck <br />traffic to other traffic. <br />• Most common data available for making damage comparisons is ESALs. MnDOT uses a <br />formula of one garbage truck equivalent to 1,000 car trips. <br />• The City of Falcon Heights attributed the impact of garbage trucks on roads as high in <br />alleys (about 86% of impact due to garbage trucks) and low in heavily traveled areas <br />(about 8% due to garbage trucks). This seems reasonable since in heavily traveled areas, <br />garbage trucks make up a much smaller percentage of the total number of heavy vehicles <br />than in urban alleys. <br />• The City of Arden Hills noted that environmental factors are generally responsible for a <br />majority of pavement deterioration on the city's 9-ton streets. <br />The presentation also discussed cost estimates of road impacts from various cities. <br />• The City of Roseville (with an open system) estimates $20 to $40 per household per year <br />in pavement damage due to garbage trucks (totaling about $188,000 to $376,000 per <br />year). <br />• The City of Oakdale (also with an open system) reported an estimate of $120,000 to <br />$300,000 per year. <br />
