3 cards from this section. Quick, good the night before a test.
What is the purpose of a dowel bar in rigid pavement?
Think about the role of the dowel as a connector of weight.
Define thermal expansion in concrete.
What happens to materials when they get warmer?
What type of joint accommodates thermal expansion in concrete?
Think about which joint type deals with heat.
True or False: Tie bars are used to transfer loads between two concrete slabs.
Consider the role tie bars play versus dowel bars.
Design an expansion joint for a concrete pavement 25 cm thick for an area experiencing temperature variations of 25°C throughout the year. Determine the joint width needed.
Consider the thermal coefficient for concrete and use the temperature change.
Given the wheel loads acting on multiple lanes of pavement, analyze the point of maximum stress for both edge and corner conditions. Elucidate steps taken.
Refer to appropriate equations based on load types and positions.
