 contours, using heavy solid lines at one foot intervals with storm drainage flow arrows along
earth swales and irregular pavement surfaces. Provide complete retaining wall details
including graded filter material and provisions for drainage. Provide the finish elevations at
all corners and grade breaks for all buildings and concrete slabs and indicate the top
elevation and inverts of all drainage structures. Additional spot elevations shall be
provided along ditches at culvert inverts and at all other critical surface positions to clearly
indicate surface runoff. Indicate the limits of grading. Indicate the location of the disposal
or borrow area and hauling routes. Location of test pits may be shown on this plan. Spot
elevations on the ground shall be shown to the nearest tenth of a foot and those on
structures or pavements to the nearest one-hundredth of a foot. The vertical control
benchmark, shown on the existing topography plan, shall be repeated on this plan.
7.5.1.6 Paving Plan
Orient and scale the paving plan the same as the plot/site plan. The pavement plans shall
show the location, limits, and alignment of all airfield pavements, parking areas, storage
areas, roads, curbs and gutters, walks and patios. Pavement surface, base course, sub-
base course materials and thickness shall be indicated by note and legend symbol. Earth
shoulder and subgrade preparation and compaction requirements shall be indicated by
note. Rigid pavement layout shall indicate the joint pattern, identifying the type of joint by
line or note symbol. Design surface elevations shall be indicated around the perimeter,
and along all construction joints at slab corners at 75' to 100' intervals, or more often, as
may be required, to reflect changes in grade. Transition pavements and fillets on airfield
pavements or road intersections will require additional surface elevations to establish the
transition grades or warped surfaces. Steel reinforcement or temperature steel location,
sizes and spacing shall be indicated by note, symbol or enlarged detail on the same
drawing or on a detail drawing. All embedded structures or items such as manholes, pits,
tie-downs, ground receptacles, etc., shall be indicated and their effect on the standard joint
pattern shall be shown. Design wheel loading for airfield and roadway pavements, grating
and covers shall be noted. Design surface elevations for flexible pavements shall be
indicated around the perimeter, at curb inlets and catch basins, and at locations within the
paved area to reflect changes in grade. Crowned road pavements shall have surface
elevations indicated along the roadway centerline and along both edges. Super-elevation
diagrams shall be shown for the curved road. Sidewalk and patio pavements shall indicate
the joint pattern, set at grade of control curb or building line or conform to adjacent
topography, and shall indicate a design transverse slope to assure free-draining surface.
Typical cross-sections of all pavement design sections on the project shall be shown on the
paving plan or shown on a detail drawing and crossed-referenced. Special pavement
details including joint details, steel reinforcement, tie-downs, grounding receptacles, curb
or curb and gutter sections, new pavement abutting existing pavement, etc., may be shown
on the paving plan or shown on a detail drawing and cross-referenced.
