Unsurfaced Road Maintenance Management


Quiz Questions

1.An installation’s unsurfaced road network consists of all unsurfaced areas that provide access ways for ground traffic, including roadways, parking areas, storage areas, tank trails, and range roads.
True
False
2. A branch is an identifiable part of the unsurfaced road network that is a single entity and has a distinct function.
True
False
3.A section is a division of a branch; it has certain consistent characteristics throughout its area or length.
True
False
4.The section characteristics are:
 (1) Structural composition (thickness and materials).
 (2) Construction history.
 (3) Traffic.
 (4) Surface condition.
True
False
5. A sample unit is an identifiable area of the unsurfaced road section; it is the smallest component of the unsurfaced road net-work.
True
False
6.Structure is one of the most important criteria for dividing a branch into sections. Structural information is not always avail- able for all branches of an unsurfaced road net-work.
True
False
7.The unsurfaced road condition index is a numerical indicator based on a scale of 0 to 100. The URCI indicates the road’s integrity and surface operational condition.
True
False
8.There are two methods of inspections. The first is a quick survey done from a moving vehicle. The second involves detailed measurements of distresses in the sample units.
True
False
9.What does figure 3-1 illustrate about?
(Refer Pg 3-2)
URCI scale and condition rating
Unsurfaced Road
Structural composition
None of the above
10.A section is a division of a branch with consistent characteristics of the following:
(1) Structure.
(2) Traffic.
(3) Construction history.
(4) Road rank.
(5) Drainage and shoulders.
(6) A sample unit
True
False
11.The manual recordkeeping system consists primarily of the two forms. Those forms are used for information storage.
True
False
12.The manual data management system is a systematic way of recording and storing information needed for effective road maintenance management.
True
False
13.The unsurfaced roads management system is a component of the Micro PAVER pavement management system.
True
False
14.Generally, the computerized system is recommended for expedient data handling and report generation. It may become advantageous to use it for road networks with a large number of road sections (more than 200).
True
False
15.An unsurfaced road should have a crown with enough slope from the centerline to the shoulder to drain all water from the road’s surface.
True
False
16.Poor drainage causes water to pond. Drainage becomes a problem when ditches and culverts are not in good enough condition to direct and carry runoff water because of improper shape or maintenance.
True
False
17.What does figure B-1 illustrate about?
(Refer Pg B-2)
High severity example of improper cross section
Improper cross section
Severity levels.
None of the above
18.The wear and tear of traffic on unsurfaced roads will eventually loosen the larger particles from the soil binder.
True
False
19.Potholes are bowl-shaped depressions in the road surface. They are usually less than 3 feet (1 meter) in diameter.
True
False
20.A rut is a surface depression in the wheel path that is parallel to the road center- line. Ruts are caused by a permanent deformation in any of the road layers or sub-grade.
True
False
