against both public traffic and traffic caused by the contractor's employees and agents for a period of
28 days. In order that the pavements be properly protected against the effects of rain before the
pavement is sufficiently hardened, the contractor will be required to have available at all time materials
for the protection of the edges and surfaces of the unhardened RMP. The protective materials and
method of application shall be the same as previously described in paragraph PRIOR TO GROUTING.
When rain appears imminent, all paving operations shall stop, and all available personnel should cover
the surface of the hardened RMP with protective covering.
