a. Road Classifications. Roads outside the limits of the United States are classified on both large-and medium-scale maps as--
(1) Hard-surface, all-weather roads.
(a) Two or more lanes wide.
(b) One lane wide.
(2) Loose or light surface, all-weather roads.
(a) Two or more lanes wide.
(b) One lane wide.
(3) Loose surface, fair-or dry-weather roads.
(4) Tracks.
(5) Trails.
b. Hard-Surface, All-Weather Road. These roads carry fairly heavy truck loads in all weather. Minimum maintenance requirements are periodic inspection and repair. The construction is usually concrete or asphaltic concrete, bituminous macadam, surface-treated oiled gravel, and light tar-bound macadam.
c. Loose or Light Surface, All-Weather Road. These carry light loads in all weather. The roads generally are drained and graded. Periodic maintenance is required. Construction is usually of gravel, stone, or some stable material, such as sand-clay, on a light foundation.
d. Loose Surface, Fair-or Dry-Weather Road. These roads carry light loads in dry weather only. The road may or may not be graded or drained and requires continual maintenance. Any surfacing consists of gravel, or sand-clay with a poor foundation.
e. Tracks. Tracks include winter roads, caravan routes, and natural roadways and can accommodate very light vehicles, such as ¼-ton trucks, in dry weather. Tracks are normally shown only in areas having poor road systems.
f. Trails. Trails include important foot trails, foot paths, and pack trails. Minor trails and unimportant connecting trails are omitted. In areas with good road systems, tracks are included in this category.
g. Symbols. The following contain the approved symbols for roads in foreign areas.
