The projected AADT during the first year of operation is 3900 (both directions). If the traffic growth rate is estimated at 3% and the CBR of the subgrade is 7.5, determine the depth of a full-asphalt pavement using the AASHTO method and n = 20 years. The resilient modulus of the asphalt (EAC) is 320,000 lb/in2. Assume mi for the subgrade is 1 and the percent of traffic on the design lane is 42%, pt = 2.5 and SN = 4. Use a reliability level of 90%, a standard deviation of 0.45, and a design serviceability loss of 2.0.
The predicted traffic mix of a proposed four-lane urban non-interstate freeway: Passenger cars = 78% Single-unit trucks 2-axle, 5,000 lb/axle = 12% 2-axle, 9,000 lb/axle = 4% 3-axle or more, 23,000 lb/axle = 3% Tractor semitrailers and combinations 3-axle, 20,000 lb/axle = 3% What will be an ideal response?
A piping system that has the main supply pipe from the boiler enter the first baseboard unit, all baseboard sections connected in series, and the outlet from the last baseboard section connected to the circulator pump, which connects to the boiler, is called a:
A) One-pipe, venturi piping system. B) Series loop, single circuit hot water piping system. C) Series loop, double circuit. D) Two-pipe, reverse return hot water piping system.
Each township measures.
