Construction joints in the pavement are generally created by ___________________.

• A. Scoring concrete with a grooving tool
• B. Saw cutting the hard concrete
• C. Rounding corners with the edger tools
• D. All of these

Answer: (D)

Construction joints in pavement are formed to provide a controlled plane for cracking and to separate pours placed at different times. You can create these joints by scoring the fresh concrete with a grooving tool to establish a contraction joint, by saw-cutting the concrete after it has set to establish a clean, precise joint plane, and by rounding the corners with edger tools to smooth the joint area and prevent edge damage as the pavement cures. Each method contributes to defining or refining the joint, so using all of them is common practice.
