Above-normal rainfall so far for the month of February could have also significantly impacted the asphalt.
The normal rainfall total for February is 1.49 inches, which has already been broken by the current total of 2.69 inches so far for the month.
Below-freezing temperatures affecting the citrus groves also brought similar cold to Daytona in early January. Pavement cracks are much more likely in colder climates, which usually isn't an issue for Florida.
