Calculate ESAL in the design lane for 20 year design period for asphalt (assume TSI= 2.5) and concrete (assume TSI= 2.5 and D = 9 inch) pavement, respectively, based on the initial traffic of single axle-loads shown below, given that the yearly rate of growth 2%, Direction Distribution Factor =50%, Lane Distribution Factor = 75% Axle Load Number (kip) 18 20 22 24 26 28 30 32 34 per day 61.4 47.2 21.4 12.9 6.1 2.9 1.2 0.7 0.3

A flexible pavement has the following class loads during a particular hour of the day. i. ii. 80 buses with 2-axles (each axle load of 40 kN) ; ii. 160 trucks with 2-axles (from and rear axle loads of 40 kN and 80 kN, respectively) Find the equivalent standard axle load repetitions for this vehicle combination as per IRC 37-2012.

2 a. The scales reading the weight of each truck were reading 10% low. Calculate the ESAL for the following truck, assuming flexible pavement for both the axle/axle group weight and the weight increased by 10% 12,000 lbs 40,000 lb shoporst 20,000 b. Calculate the ESAL for the above truck, assuming rigid pavement. 20,000

Please explain this transportation egnieering problem in a better explantion. This problem is related to pavement design,I don't know how to start or what the main purpose is, how can I go about it with this problem. Please help me

A section of a two-lane rural highway is to be realigned and replaced by a four-lane highway with a full-depth asphalt pavement. The AADT (both ways) on the existing section can be represented by 500 ESAL. It is expected that construction will be completed 5 years from now. If the traffic growth rate is 5 percent and the effective CBR the subgrade on the new alignment is 8.5, determine a suitable depth of the asphalt pavement (in inches) using the AASHTO method. Take the design life of the pavement as 20 years. The resilient modulus of the asphalt (EAC) is 400,000 lb/in.². Assume m, for the subgrade is 1 and the percent of traffic on the design lane is 45 percent. Use a reliability level of 90 percent, a standard deviation of 0.45, and a design serviceability loss of 2.0. inches

The data given below pertain to the design of a flexible pavement. Initial trafic = 1213 cvpd Traffic growth rate = 8 percent per annum Design life = 12 years Vehicle damage factor = 2.5 Distribution factor = 1.0 The design traffic in terms of million standard axles (msa) to be catered would be

Discuss the pros and cons of JPCP versus JRCP. What is meant by the mechanistic-empirical method of pavement design? Is it possible to develop a wholly mechanistic method of pavement design? Why?

A section of a two-lane rural highway is to be realigned and replaced by a four-lane highway with a full-depth asphalt pavement. The AADT (both ways) on the existing section can be represented by 750 ESAL. It is expected that construction will be completed 5 years from now. If the traffic growth rate is 2 percent and the effective CBR of the subgrade on the new alignment is 9.0, determine a suitable depth of the asphalt pavement (in inches) using the AASHTO method. Take the design life of the pavement as 20 years. The resilient modulus of the asphalt (EAC) is 450,000 lb/in.2. Assume mi for the subgrade is 1 and the percent of traffic on the design lane is 45 percent. Use a reliability level of 90 percent, a standard deviation of 0.45, and a design serviceability loss of 2.0.

A six lane divided highway is being designed for a current AADT of 6000 vehicles with a growth rate of 5% and a design life of 20 years. If the vehicle mix is 60% passenger cars (2 kips), 30% 3-axle single unit truck (12 kips) and 10% 3-axle tandem trailer (30 kips). The pavement has a terminal serviceability index (pt) of 2.5 and Structural Number (SN) of 5. Determine the design ESAL?
