A state toll highway authority is planning to expand the pavement deflection monitoring program for its 500 miles of toll highways. The requirements state that a 20 percent change in pavement deflection should be detectable in at least 9 out of every 10 tests. If the state authority currently monitors 100, 1-mile-long segments, determine the expansion needed in its deflection program to comply with the new requirements.

A pavement designer has arrived at a design traffic of 100 million standard axles for a newly developing national highway as per IRC:37 guidelines using the following data: design life = 15 years, commercial vehicle count before pavement construction = 4500 vehicles/day, annual traffic growth rate = 8%.

What is the K- design value for a roadway designed for 70 mph, and G₁--2.5% and G2=3.9%?
A pavement has a design life of 20 years and design traffic of 75 msa for a newly developing National Highway. Number of commercial vehicles after construction of pavement is 4200 vehicles per day. If vehicle damage factor is taken as 1.05 and annual rate of traffic growth is taken as 8%, then the value of lane distribution factor adopted is. (Round off to two decimal places).
From the traffic counting in 2020, the average commercial vehicle per day is 500 (10% commercial vehicle) and the traffic growth rate is estimated at 5%. A pavement needs to be designed for 15 years and is expected to open for the public in 2022. Using ATJ 5/85 method, estimate the total number of vehicles per direction during the first year of service. * 100740 213669 O 1108240 O 2173824
