PART 2-- FORMWORK AND CONCRETE MATERIALS
2.1 FORMWORK MATERIALS
C. MISCELLANEOUS MATERIALS INCLUDE:
Flashing reglets: Galvanized steel as manufactured for this purpose with splines to align joints.
Waterstops: Polyvinyl chloride. Construction joints: Tongue and groove extruded plastic as
manufactured for this purpose. Joint filler: Premolded asphaltic board as per ASTM D 1751. Form-
release agent: Clear mineral oil, non-staining, as manufactured for formwork.
D. Vapor retarder for concrete slab on or below grade: 6 mil clear polyethylene.
2.2 REINFORCING MATERIALS
A. Reinforcing bars: Deformed steel bars,Grade 60,Type S,to comply with ASTM A 615. Plain finish
bars may be used in spiral. Fabrication to comply with CRSI Reinforcing Bar Detailing.

!�* B. Uniformly apply base course materials of correct thickness. Spread sub-base material to total
compacted thickness shown in Drawings. Compact to 95%.
*Note to specifier: sub-base is for larger paving areas and special conditions. Verify need for sub-base
with civil engineer.
3.3 ROLLING AND TOLERANCES
A. Properly slope paving surface to drain. Roll out irregularities such as humps or dips. Operate rollers
only where soil has been compacted. Do not allow rollers to damage curbs or adjacent paving. After
spreading, roll until surface is hard and smooth to finish elevations shown on Drawings. Roll in multiple
directions until no roller marks are visible. Smoothness tolerance: 1/8" in 6'.
�. B. Confirm final bituminous paving thickness at randomly selected locations. Compacted thickness
within tolerance of minus 0.0" to plus 0.5". Tolerance limit 3/8" in 10'maximum deviation from grade
elevations shown on Drawings. Variation from true elevation may be 1/2" or less.

3.4 COMPLETION,TESTING, REPAIR AND CLEAN UP
A. Redo,repair, and recompact the work as required to meet specified standards. Remove spillover
material, and clean adjacent pavements of spills. Repair any damage to adjacent areas.
B. Before sealing, flood test pavement. Thoroughly flood paved area with water and if water ponds to
depth of more than 1/8 in 6', fill and correct to provide drainage. Smooth the edges of all corrected work
until repairs are invisible.
C. Apply seal coat according to manufacturer's instructions to create a finish seal which drys to a
uniformly smooth, black,surface. Protect sealed area from traffic until sealer has cured and is safe for
traffic.
LANDSCAPING 02900
All Final grading will be completed by the General Contractor. All landscaping will be the responsibility of
the Owner.
