Construction joints in pavement are generally created by which methods?

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

Answer: (D)

Construction joints are intentional break lines in pavement that allow for controlled cracking and movement with temperature and shrinkage. Scoring the surface with a grooving tool creates a shallow, predefined plane where the joint will form. Saw cutting the hardened concrete produces a precise, deeper joint at the exact location after initial set. Rounding corners with edger tools finishes the edges and helps define and protect the joint area, reducing edge damage near the joint. Together, these techniques cover the typical ways pavement joints are established, so using all of them is common practice.
