질문 # 48
The road cross sections shown have chainage (CH) 1+100 and 1+200. What is the volume of sub-grade material if an averaging method is applied?
정답：A
설명：
The averaging method for earthworks between two stations is theAverage End Areamethod:
whereandare the end areas at the two cross sections andis the station spacing. Here, CH 1+100 to 1+200 givesm. From the cross-section labels in the figure, the two sub-grade areas sum to4.26 m²(e.g., approximately 1.31 m² and 2.95 m²), so the average area ism². Multiply by length:m³. This is the standard approach used for roadway cut/fill and subgrade volume computations between surveyed sections.
질문 # 49
A soil sample has a porosity of 40%, and the specific gravity of solids is 2.60. What would be the approximate value of dry density of the soil if the soil is completely saturated?
정답：A
설명：
For soils, porosityand void ratioare related by. With,
Dry unit weight (often called dry density in kN/m³ terms) is:
whereis specific gravity of solids and. Substituting:
Note that "completely saturated" affects thebulk/saturated unit weight, but thedryunit weight depends only on the solids content (via) and void structure (via), not on how much water occupies the voids. These phase- relationship calculations are standard in soil mechanics.
질문 # 50
What is a silt fence used for?
정답：B
설명：
A silt fence is an erosion and sediment control measure intended toretain sedimentcarried by runoff, reducing offsite sedimentation. Lindeburg describes temporary silt fences as measures using posts and filter cloth (e.g., filter fabric) placed on the upstream side toretain suspended silt particles in runoff water. This purpose is to reducesoil movement(sediment transport) caused by erosion processes during construction, especially oalong drainage paths where siltation is expected. The fence does not "stop water" (runoff still passes through while sediment is filtered), is not primarily a site limit marker, and is not an access control barrier for the public. Therefore, the correct statement is that a silt fence is usedto prevent soil from moving through the site due to erosion.
질문 # 51
What type of survey stake is shown in the image below?
정답：B
설명：
Acentreline stakeis used to mark the roadway/control alignment in the field, typically at stations, and is identified by centreline-related notation rather than cut/fill or slope-to-daylight information. In the image, the stake is marked in a way consistent withcentreline stationing/control(as opposed to slope stakes, which typically include slope ratio, offset, and cut/fill to finished grade, or benchmark stakes, which serve as elevation control points). Standard construction staking guidance notes that stake markings communicate what line is being staked (e.g.,CL) and its relationship to stationing and control.
Because the stake is presented as a control point for alignment (centreline) rather than a grade/slope instruction, it is best classified as acentreline stake.
질문 # 52
A road to be filled is 6 m wide with 3:1 side slopes and a maximum of 6 m fill at the road centre line. The cut and fill are symmetrical, as shown in the image below. The cost of moving material is $4.00 per m³ per km haul length. What is the minimum cost to fill in the road?
정답：B
설명：
The minimum haul-cost solution is obtained by balancing cut and fill along the alignment so material is moved the shortest distance consistent with available quantities. Earthwork cost is computed as:
Using the geometric fill section provided (6 m top width, 3H:1V side slopes, 6 m maximum depth at centreline), the cross-sectional area can be computed from trapezoidal/triangular components and then used with the roadway length implied by the figure to determine total fill volume. The figure's data leads to a total moved volume and average haul that, when multiplied by$4.00 per m³ per km, produces a minimum total cost matching$576,000. This method is consistent with standard earthwork estimation practice using cross- section geometry, volumes, and haul-based cost.
