Question

how can expansion joints help prevent the cracking of asphalt due to thermal expansion? they put more pressure on the asphalt to stop it from expanding. they give the asphalt more room to expand as it heats up. they put pressure on different parts of the asphalt.

Explanation:

When asphalt heats up, it expands. Expansion joints create space for this expansion. If there were no expansion joints, the expanding asphalt would have nowhere to go, leading to cracking due to internal stress. So, expansion joints allow the asphalt to expand freely as it heats up.

Answer:

They give the asphalt more room to expand as it heats up.
