Section numbers referred to hereinafter are those of the referenced standard. 1.3 CONDITIONS A. Earthwork: Subbase completed and accepted. B. Underground Work: Piping and conduits installed, inspected, accepted, backfilled and compacted. C. Drainage Structures: Catch basins, inlets, manholes and the like within areas to be paved, complete and accepted. D. Environment: Apply no bituminous material when the temperature of the air is less than 40 F. in the shade or when the weather condition or the existing surface is unsuitable. 1.4 COORDINATION A. Coordinate pavement work with installation of underground work and fence work. 1.5 PROTECTION A. Where new pavement occurs adjacent to work that will remain, take all precautions as necessary to prevent damage to such existing work. Paving within two (2) feet of existing buildings shall be accomplished by hand work. Protect work of others from damage by operations under this Section. Upon completion keep traffic off finished surfaces for 48 hours. BITUMINOUS PAVING

2 B. Cuts made through any paved surface must be repaired i n a nondiscernible fashion. Cuts through concrete must be repaired by replacing the section between the nearest two joints - either construction or expansion. Cuts through asphalt must be repaired so that depressions or humps do not develop during the warranty period - if they do, they will have to be re-worked until corrected, at the contractor's expense. Asphalt and base compaction by "normal traffic" is not permitted. When cuts extend through pavement markings, the replaced pavement shall be marked to match the existing. 1.6 WARRANTY A. Written statement signed by responsible official that finish course will not develop cracks 1/4 inch wide within 5 years after completion and that any such that appear will be filled, using asphaltic concrete and rolled (to restore area to uniform appearance) without additional cost to Owner.
