Note 2. The bituminous material used for the bituminous coated aggregate slope wall shall be RS-2 or RC-70. Art. 511.03 Slope Wall CONSTRUCTION REQUIREMENTS
511.03 General. Preparation of the earth bed, excavation, backfilling, and
disposal of surplus material shall be according to Section 502.
a.Reinforced Concrete Slope Wall. Reinforced concrete slope wall shall be according to Section 503 and constructed in alternating sections, each approximately 9 ft (2.7 m) in width. Concrete slope walls shall be reinforced with welded wire reinforcement, supported 2 in. (50 mm) below the upper surface of the slope wall by concrete blocks. A clear distance of 2 in. (50 mm) shall be maintained between the welded wire reinforcement and the outside face of any vertical or inclined anchor or cutoff wall. The welded wire reinforcement shall be continuous across construction joints and shall extend into each section a minimum of 6 in. (150 mm) from any adjacent previously placed section. Adjacent sections of welded wire reinforcement shall be lapped a minimum of 6 in. (150 mm).
b.Bituminous Coated Aggregate Slope Wall. Bituminous coated aggregate slope wall shall consist of crushed aggregate placed on the prepared slope, shaped and compacted to the satisfaction of the Engineer. After the aggregate has dried to the satisfaction of the Engineer, the bituminous material shall be applied at a minimum rate of 1 gal/sq yd (4.5 L/sq m). The rate shall be sufficient to penetrate and bind together the particles in the upper 2 in. (50 mm) of the crushed aggregate. The adjacent structure shall be protected from bituminous material to prevent spattering or discoloration.
511.04 Method of Measurement. This work will be measured for payment as
follows.
a.Contract Quantities. The requirement of the use of contract quantities shall be according to Article 202.07(a).
b.Measured Quantities. This work will be measured for payment in place and the area computed in square yards (square meters). The area for measurement will include the upper, sloped surface of the wall. Anchor and cutoff walls will not be measured for payment.
511.05 Basis of Payment. Reinforced concrete slope walls will be paid for at
the contract unit price per square yard (square meter) for SLOPE WALL of the thickness specified. Concrete protected according to Article 1020.13(d) may be paid for at the adjusted unit prices according to Article 503.22. Bituminous coated aggregate slope walls will be paid for at the contract unit price per square yard (square meter) for BITUMINOUS COATED AGGREGATE SLOPEWALL, of the thickness specified. Piling Art. 512.04 SECTION 512. PILING
512.01 Description. This work shall consist of furnishing and driving piles.
512.02 Materials. Materials shall be according to the following.
Item Article/Section
a.Timber Piling ...................................................................................... 1007.08
b.Preservative Treatment ..................................................................... 1007.12
c.Portland Cement Concrete (Note 1) ....................................................... 1020
d.Reinforcement Bars and Welded Wire Reinforcement ...................... 1006.10
e.Structural Steel .................................................................................. 1006.04
f.Structural Steel Coatings ........................................................................ 1008
