2 cards from this section. Quick, good the night before a test.
What causes temperature stresses in rigid pavements?
Think about the daily and seasonal effects.
What is warping stress?
Consider daily temperature variations.
What is the primary cause of temperature stresses in cement pavements?
Think about what affects material expansion and contraction.
True or False: Warping stresses are created by seasonal temperature variations.
Recall the difference between daily and seasonal changes.
Given a slab of thickness 20 cm with a modulus of elasticity of 300,000 kg/cm², calculate the warping stress induced by a temperature gradient of 15°C. Assume relevant coefficients.
Remember to break down the equation into parts for lesser complexity.
Analyze how seasonal temperature changes affect frictional stresses in a concrete pavement using the unit weight and coefficient provided in the frictional stress formula.
Focus on the formula and ensure units match for accurate calculations.
