- 393 - SECTION 601 -- GENERAL REQUIREMENTS
601.01 General
1.This Section describes materi als, procedures and equipment that are common to items of work described in Division 600. The requirements in Section 601 are applicable to all work, unless otherwise indicated.
2.The Contractor shall protect concrete pavement from any damage including but not limited to damage due to precipitation or freezing conditions.
3.The Contractor shall replace any concrete damaged by precipitation, freezing, or other conditions at no additional cost to the Department.
4.The Contractor shall always have materials readily available to protect the surface and t he edges of the concrete.
5.No section of concrete pavement will be opened to traffic without providing the Engineer adequate advance notice to inspect joints, check the pavement surface, and schedule the coring unit.
6.The method used to place concrete shall not allow the concrete materials to segregate or displace rein forcing steel. The impact of any free fall must be kept to the lowest levels consistent with efficient placement.
7.Curing compounds shall not be placed on any surface that will be bonded to another concrete surface.
8.The Department is responsible for the initial cores on all Portland cement concrete pavement.
601.02 Equipment
1.a. All placing and finishing equi pment shall be at the job site one full NDOT work day before its intended use to allow the Engineer time to examine it.
b.On small urban projects, the equipment will be examined before the work starts. However, the equipment need not be on site 1 day before the paving.
2.Garden rakes shall not be used to handle or move concrete. 3. Equipment shall meet t he requirements of Section 1002.
4.The subgrade profiling equipment shall be capable of meeting the Construction methods of Section 302. Electronically controlled profiling equipment will not be required when subsequent construction uses formed construction methods.
5.Concrete spreaders shall be self-propelled and able to spread and strike off concrete. The spreader may be an independent machine or combined with the finishing machine. Mechanically drawn strike off blades shall not be employed unless hand finishing methods are allowed. Self-propelled concrete spreaders shall be equipped with the following devices:
a.A power-driven system capable of uniformly spreading the concrete transversely without segregation.
b.An adjustable strike-off screed capable of leveling the concrete surface at the required elevation inside the forms.
