<br /> Comprehensive Review of <br /> S olid W aste Collection and Disposal Options <br /> <br />v2.1 83 10/22/12 <br /> Assuming a typical compaction density of 750 pounds per cy, the waste in a fully <br />loaded 19 cubic yard vehicle may weigh 14,250 pounds; <br /> Thus the total gross weight of a loaded vehicle would equal 39,100 pounds; <br /> Depending on the distribution of the total load between axles, the tandem axle weight <br />limit transmitted to the road (38,000 pounds) may be exceeded; and, <br /> For the Town’s older single-axle collection vehicles, assuming 2/3rds of the total gross <br />load is distributed over a single rear axle, the single-axle weight limit (20,000 <br />pounds) would be exceeded. <br />- 39,100 pounds * 0.66 = 25,806 pounds <br /> <br />6.3.1.3 Commercial Collection Vehicles <br />The Town’s existing commercial front loader collection trucks have a rated capacity of 28 cy. <br />According to data provided by the Town, the tare weights of these tandem-axle commercial front <br />loader vehicles range between 38,000 to 39,000 pounds (approx. 19 tons). Based on the known <br />tare weight of the Town’s collection vehicles and their waste hauling capacities, these <br />commercial vehicles are subject to potential overweighting depending upon their axle <br />configuration and the load weight distributed across their axles. For example: <br /> Assuming a typical compaction density of 750 pounds per cy, the waste in a fully <br />loaded 28 cubic yard vehicle may weigh 21,000 pounds; <br /> Thus the total gross weight of a loaded vehicle would equal approx. 59,000 pounds; <br />and, <br /> Assuming two-thirds of the total gross load is distributed over the rear tandem axles, <br />the tandem axle weight limit transmitted to the road as determined by the distance <br />between axles (min. 38,000 pounds at 8 feet or less) may be exceeded. <br />- 59,000 pounds * 0.66 = 38,940 pounds <br /> <br />6.3.1.4 Fleet and Routing Modifications <br />Accordingly, fleet and routing modifications are necessary to: <br /> Enable the Town’s existing single-axle residential trucks to comply with the NCDOT <br />weight limit; <br /> Enable the Town’s existing tandem-axle commercial trucks to comply with the <br />NCDOT weight limit; and, <br /> Accommodate for periodic use of single-axle residential collections vehicles.
