Is It Ok To Pave In The Rain?

slide-16
SLIDE 16

Considerations

  • Weather Restrictions
  • Rain
  • If Temperature < 55 °F – cannot pave
  • Utilities

○ Although utilities are supposed to be marked there is a high probability that

something is underground that is unknown.

○ Not uncommon to have depths above expected levels

  • Other Considerations

○ Murphy’s Law
