My reputation is to low to comment but that looks like frost heave to me, does this area experience freezing temperatures?

If it is frost-heave the answer is generally proper drainage and replacing the susceptible materials under the pavement.

EDIT: As suggested by Phil Sweet this could also be blistering. There are several types of blistering and the remediation depends on the underlying cause. Blistering can be caused by a number of factors and would require inspection by a professional to determine the cause.

  • $\begingroup$ @PhilSweet actually many palm tree species can handle freezing temperatures. Also an area that seldom experiences freezing temperatures is less likely to consider frost heave when constructing roads. $\endgroup$ Jan 26 at 2:41
