DESIGN OF VEHICULAR AND PEDESTRIAN PAVEMENT:
14.1
General: Design the pavement to reflect topography, soils,
climate, local materials, function, and other requirements and
specific situations. Provide sufficient details to construct all
pavement elements. Consider local materials and design details.
Use Program Guide PG-18-4 as a guide for developing details.
14.2
Public Road Intersections: Intersection design of VA roads with
public roads must receive joint approval of VA Office of
Facilities Management and the local municipal authorities.
14.3
Pavement Construction:
A.
Design pavement sections of all roads, service areas, fire
apparatus vehicle accessibility areas, and parking areas for
the maximum anticipated traffic loads and existing soil
conditions.
B.
Construct service areas for bulk oxygen storage, laundries,
warehouses, kitchens, canteens, utility buildings, and similar
facilities of reinforced concrete.
C.
Where required, provide a concrete paving joint pattern plan
and details.
D.
Construct roads and surface parking of asphaltic concrete.
E.
Principal roads and primary service roads should be 7200 mm
(24'-0") wide between faces of curbs. Secondary service roads
should be 3600 mm (12'-0") between faces of curbs.
14.4
Curbs and Gutter: Design all roads with integral concrete curbs
and gutters. Substitute free-standing curbs only when justified.
A.
Curb Radii: The radii of curbs at road intersections should
be 9000 mm (30'-0"), preferred; 7500 mm (25'-0"), minimum.
