ASSIGNMENT -1 PAVEMENT ANALYSIS AND DESIGN (Units Covered: 1, 2, 3 & 4)
Date of submission: on/before 27-08-2015
1. (a) What are the different variables considered in pavement design and explain role of each factor.
(b) Calculate the radius of tyre contact area if tyre pressure is 0.8Mpa and wheel load is 50KN.
2. Write a detailed note with sketches about Marshall Method of Mix Design.
3. The plate load tests were conducted with 30 cm plate diameter on soil sub grade and over 15 cm base course. The pressures yielded at 0.5 cm deflection are 1.25 kg/cm2 and 4kg/cm2, respectively. Design pavement section for 4100kg wheel load with tyre pressure of 5 kg/cm2 for an allowable deflection of 0.5 cm using Burmister's approach.
4. Using IRC:37-2001 guidelines for the design of flexible pavements and the following data, Choose the total thickness of the pavement.
No of Commercial Vehicles when construction is completed=3000cvpdTwo lane carriage wayAnnual growth factor=7.5%Design life=10yearsCBR Value of Subgrade=5%(Assume suitable data from IRC-Code book)
