Program Description:

Bonded and unbonded topping slabs may seem similar, but their behaviors are fundamentally different and they required different design and construction. Failure to appreciate the differences can result in cracking, debonding, and performance issues. This session will explore the differences between the two, discuss materials- and installation-related causes of failures, and provide guidelines to properly implement each type of topping slab.

Learning Objectives:

Through attending this program, registrants will be able to:

  1. Explain the different behaviors of bonded and unbonded toppings and how they are different.
  2. Understand how to design and construct the two types of topping slabs.
  3. Identify, understand, and recognize common causes of failures.
  4. Select materials and proportions to enhance the likelihood of successful topping installation.
  5. Describe proper techniques to successfully install overlays and toppings.
