heavy equipment vehicle parking, or of concentrated vehicle turning movements and
maneuvering, should receive PCC.
3.2.3.1.3 Other areas that normally require PCC are aprons for OMS/AMSA/DS/GS
buildings, wash platforms, fueling platforms, loading dock parking and drives, and
dumpster pad/pickup zones. Some access approaches, and heavily used drives or
streets, may merit consideration for PCC paving. If a Mobile Kitchen Trailer (MKT) is
authorized, it will require a concrete pad, preferably near the TC kitchen.
3-2.3.1.4 It is recommended to adapt pavement specifications to the state s Department
of Transportation (DOT) Standard Specifications for Roadway Construction. Local
pavement materials suppliers and paving contractors are likely to have state DOT
certifications for material sources, screen plants, batch plants, transporters, and pavers
used for pavement material production and placement.
3-2.3.1.5 AC pavement mixes should be relatively stiff to prevent wheel rutting or
surface raveling during heavy use and periods of high temperatures. The state DOT
highway mixes should address this situation. In some cases, the stiffer mix may have a
coarser surface finish, but its strength and serviceability advantages are preferred.
3-2.3.1.6 Pavements or aggregate surfacing may require subgrade improvement
measures to limit rutting or breakup over softer subgrades. Soil replacement is the
preferred subgrade improvement option, but geotextiles should be considered where
the improvement excavation would be deep or the area of needed improvement
extensive. Obtain the recommendations of a local geotechnical engineer or the
Government installation public works department.
3-2.3.1.7 Use of recycled aggregates for base materials and pavement mix aggregates
should be allowed as a recycling/sustainable design measure. State DOT specification
provisions for recycled aggregate should be reviewed for restrictions or limitations on
use.
3-2.3.1.8 Provide painted striping in POV and MEP areas, and elsewhere as needed.
3-2.3.2
Curb and Gutter
3-2.3.2.1 Use of curb and gutter is normally minimized for drainage, grading, and
maintenance reasons. However, use of curb and gutter may be desired to channel traffic
flow at access points, critical on-site intersections, or in areas in which vehicle traffic
needs to be strictly separated from pedestrian traffic or parking areas. Curb and gutter
are often used to define the more public or administrative areas of a facility (training
center) or to protect landscaping.
3-2.3.2.2 In areas where a number of adjacent accessible parking spaces are provided,
the designer should consider use of a "ribbon" type or flat curb at these accessible
parking spaces, so that multiple curb ramps are eliminated. This will eliminate repetitive
dips and rises in the sidewalk.
