According to Arthur Wignall, Peter S. Kendrick, and Roy Ancil, expansion joints may not be required for concrete carriageways constructed during summer months. This is because concrete expansion is primarily driven by seasonal temperature increases, from the time of construction to the peak summer temperatures. When construction occurs in summer, the concrete will experience contraction during the subsequent winter. This contraction creates space within the existing contraction joints, which can then accommodate the expected expansion during the following summer. Therefore, in this specific scenario, the installation of additional expansion joints may be deemed unnecessary.
