The orientation of the transverse joint may influence the thermal cracking as well. Amon said he cut joints at both right angles to the centerline and at 30-degree angles to the centerline. He states that both have performed similarly—in other words, both have fewer cracks than the control section of pavement without transverse joints. “We designed the pavement to crack where it was directed,” he said.
