ESALS per Vehicle 0.0007 Car 0.10 1.35 Delivery Truck Loaded 18-Wheeler 1.85 Loaded 40' Bus 5.11 Loaded 60° Articulated Bus A) Delivery truck - Assuming that the truck has two separate axles with even distribution of ESAL's. Determine the load in pounds for each of the axles in pound? B) Loaded 18-Wheler - Assuming that the 18-wheeler has a single axle on the front that carries 1/5 ESAL's and two rear double axles caring 2/5 ESALS on each. What is the front axle and each of two double axles in pound?

Civil engineering

A six-lane highway (3 lanes in each direction) is to be designed to replace an existing highway. The present AADT in one direction is 6000 and is expected to grow at 3% per year. The design life is 30 years and the vehicle mix is: Passenger cars (2000 lb/axle) = 60% 2-axle single unit trucks (6000 lb/axle) = 30% 3-axle single unit trucks (12000 lb/axle) = 10% 1) Determine the design ESAL using the AASHTO method. Exclude passenger cars. Assume SN = 4 and pt = 2.5. 2) Determine the design ESAL using CALTRANS method. Exclude passenger cars. Compare and comment on the result obtained from Problem 1. Calculate the Traffic Index using Caltrans Method. 3)

An axle weight study on a section of highway gave the following data on axle load distribution. Determine the truck factor for this section of highway. Assume  SN = 4  and  pt = 2.5.
