What is a potential consequence of overheating the screed plate?

Explanation:
Overheating the screed plate can cause it to warp. The screed plate is a flat, heated surface that smooths the asphalt as it leaves the paver. If it gets too hot, the metal expands and thermal stresses develop; uneven heating can cause the plate to bend or bow. A warped plate can’t provide a perfectly flat edge, leading to an uneven mat with thickness variations and surface imperfections. The other options don’t reflect this direct effect: heat won’t inherently increase paver wear or change mixing time, and a warped plate certainly changes the mat rather than having no effect.
