Determine the time required to complete a filling and emptying cycle for a refuse collection vehicle serving a residential area if the following conditions pertain: Truck volume 20 =yd3. Each location has on average two containers of 80 gallons each at 75% full. Refuse is picked up twice per week. Truck has a compaction ratio of 1:2. Pickup time is 1.58 min per service. Truck spends 20 min at the disposal site. It takes 35 min to drive to the disposal site. Assume a density of 250 lbs/cubic yard for uncompacted refuse and 500 lbs/cubic yard for compacted refuse.
