Why does asphalt ripple?

Asphalt can ripple due to various factors, including temperature fluctuations, underlying soil movement, and improper installation. When temperatures rise, asphalt expands, and if it isn't laid down correctly or lacks proper support, it can develop surface irregularities. Additionally, moisture infiltration and freeze-thaw cycles can weaken the base, leading to deformation and rippling. Regular maintenance and proper installation techniques can help mitigate these issues.
