質問 # 100
Which of the following tests would most likely be used to determine if engineered fill was placed to meet contract specifications?
正解:A
解説:
Engineered fill specifications are typically written in terms ofminimum relative compaction (RC)and an acceptable moisture range (often around optimum moisture content). Field verification therefore focuses on whether placed lift material achieves the specifiedin-place dry densityrelative to the laboratory maximum dry density (from Proctor testing). The compaction test (field density test) directly measures whether the fill meets the specified RC requirement. Civil engineering references describe that grading specifications set a minimum acceptable density (relative compaction) and acceptable water content range, and that the Proctor test establishes the laboratory maximum dry density and optimum moisture content used as the basis for compaction acceptance. Moisture checks alone do not confirm achieved density; sieve analysis is gradation, and triaxial testing is shear strength characterization rather than placement acceptance. Therefore, the most appropriate test to confirm engineered fill meets contract compaction requirements is acompaction test.
質問 # 101
A contractor is checking final grade elevation in advance of paving operations. What elevation needs to be confirmed before any asphalt is placed?
正解:A
解説:
Before asphalt paving, the immediate supporting layer must be at the correct line and grade because asphalt thickness is builton top of the prepared base. Thetop of baseelevation controls final pavement structure thickness and the finished riding surface elevation when combined with asphalt lift thicknesses. If base grade is too high or low, the asphalt thickness will vary outside tolerance, which can affect performance (rutting, cracking), drainage crossfall, and tie-ins at structures and curbs. Standard field inspection practice therefore verifies base course elevations (and crossfall) immediately before paving so corrections (regrading
/recompaction) can be made while accessible. This fits typical roadway QA/QC sequencing: shape and compact subgrade/base to the specified elevations, confirm, then place asphalt lifts to achieve final grade.
Hence, the elevation that must be confirmed prior to placing asphalt istop of base.
質問 # 102
Which factor aggravates a freeze-thaw cycle and contributes to asphalt pavement deterioration?
正解:B
解説:
Freeze-thaw pavement damage is driven bywater presencein cracks/voids and repeated freezing and thawing. When water enters pavement cracks and freezes, it expands and worsens cracking; repeated cycles promote disintegration and pothole formation. Poor drainage increases theavailability and residence time of waterin the pavement structure, so more water can infiltrate cracks and remain trapped in layers, intensifying freeze-thaw action and accelerating deterioration. This mechanism is consistent with documented observations that water entering cracks, freezing, and thawing expands cracks and breaks bonding, leading to potholes and rapid local deterioration under traffic. Therefore, among the given choices, the factor that most directly aggravates freeze-thaw cycles and contributes to asphalt deterioration ispoor drainage.
質問 # 103
Which of the following items appears on a record drawing?
正解:D
解説:
Record drawings (often associated with "as-built" documentation) are the finalized drawing set that reflects theconstructed conditionof the project. Their core purpose is to capture and preservefield changesand deviations from the original issued construction documents so that the owner and future stakeholders have an accurate technical record for operations, maintenance, and future modifications. During construction, changes can occur due to site conflicts, approved substitutions, design clarifications, and coordination between trades.
Those modifications must be consolidated so the final drawings match what was actually installed. In contrast, initial estimates and tender quantities belong to procurement and cost management documentation, while safety meeting minutes belong to safety administration records. A record drawing therefore focuses on revisions to the original design-locations, sizes, elevations, and details that differ from the original plan set-so that the final documents represent the "as-constructed" asset. This is why "changes from the original construction documents" is the defining item that appears on record drawings.
