4 cards from this section. Quick, good the night before a test.
What does the modulus of subgrade reaction measure?
Think about how the ground supports the pavement.
Name one type of joint used in rigid pavement.
Consider how pavements deal with temperature changes.
What is the modulus of subgrade reaction?
Think about how the subgrade supports the pavement.
True or False: Warping stress is a result of temperature changes.
Consider how heating and cooling affect materials.
Given a rigid pavement with a thickness of 25 cm, calculate the modulus of subgrade reaction required if the slab must withstand a maximum load of 2000 kg on a wheel.
Don't forget to convert units properly.
Design a contraction joint for a rigid pavement with an expected temperature drop of 20 degrees Celsius. How wide should the joint be?
Look into allowable stress for concrete and temperature coefficients.
