Compaction, grading, asphalt surfacing
Why is compaction applied to the prepared sub-grade soil?
To increase density and reduce settlement under loads
To make excavation easier for service trenches
To enhance color uniformity before paving
To allow more air voids for drainage pathways

About 20 to 30 years
Around 5 to 8 years
Roughly 35 to 50 years
Nearly 12 to 15 years
Flexible pavements are surfaced with which materials and why are they termed flexible?
Bituminous or asphalt; structure bends under traffic loads
Cement concrete; slab remains fully rigid under loads
Interlocking blocks; movement restrained by edge restraints
Stabilized soil; layers behave elastically without deflection
Which maintenance expectation best matches flexible pavements?
Require restoration roughly every 10 to 15 years
Need extensive repairs each two to three years
Are maintenance‑free throughout entire design life
Only require cleaning without structural interventions
Which layer arrangement correctly lists the typical order of flexible pavement components from top to bottom?
Surface course, base course, subbase, subgrade
Subgrade, subbase, base course, surface course
Base course, surface course, subgrade, subbase
Surface course, subgrade, base course, subbase
Which statement about rigid pavements accurately captures their structural behavior and composition?
Hydraulic cement concrete surface provides most strength
Bituminous surface relies on granular layers for stiffness
Composite asphalt-concrete layers flex uniformly with loads
Interlocked pavers transfer loads mainly through soil
Which option best defines a carriageway within a roadway cross-section?
The portion for vehicle movement only
The raised edging for channelizing water
The strip for pedestrian circulation only
The compacted shoulder outside traffic lanes
Water bound macadam (WBM) construction primarily relies on which binding mechanism between aggregates?
Water-assisted fines creating mechanical interlock
Hot bitumen coating producing adhesive bonds
Hydraulic cement paste forming rigid slab
Polymer emulsion stabilizing graded soil
Which road type is generally the most economical for low traffic rural areas but most susceptible to weather?
Earth road with gravel surfacing
Bituminous macadam surface course
Cement concrete rigid pavement
WBM with screenings and bindings
A sidewalk (footpath) is primarily provided to accomplish which design goal in urban streets?
Segregate pedestrians from vehicle traffic
Increase lane capacity for heavy trucks
Provide structural support for pavements
Collect and store stormwater runoff
Which pairing correctly matches component to function in a roadway?
Kerb – provides edge restraint and drainage channel
Shoulder – emergency stopping and lateral support
Carriageway – landscaping strip and utility corridor
Pavement – pedestrian waiting and bus bay area
When choosing between a bituminous road and a cement concrete road for a warm region with frequent maintenance access, which choice is more appropriate and why?
Bituminous road – flexible and easier to repair
Bituminous road – rigid and joint-free panels
Cement concrete road – softens under high heat
Cement concrete road – requires frequent thin overlays
During staged improvement of a village approach road, which logical upgrade sequence improves durability with moderate cost increase?
Earth road → WBM → Bituminous road
Earth road → Cement concrete road → WBM
WBM → Earth road → Bituminous road
Bituminous road → Earth road → Cement concrete
Which equipment is primarily used to compact base layers during road construction?
Dozer and scraper for rough grading
Vibratory roller for soil compaction
Concrete mixer for batching concrete
Shovel for manual excavation
Identify the equipment best suited to quickly move loosened soil over short distances on a roadwork site.
Power shovel for deep trenching
Dozer and scraper for earthmoving
Barricading for traffic control
Signage board for route guidance
A contractor must pour curbs and drainage channels. Which equipment prepares a uniform concrete mix on site?
Concrete mixer for batching and mixing
Vibratory roller for compaction
Shovel for manual backfilling
Signage board for driver information
On a busy highway rehabilitation, what combination best maintains safety and directs drivers through the work zone?
Barricading and signage board together
Dozer and scraper together
Power shovel and vibratory roller
Concrete mixer and shovels
Which site activity is shown when earth is distributed to achieve a uniform formation before compaction?
Subgrade spreading and leveling
Granular subbase placement
Final surfacing and sealing
Drainage trench excavation
During subgrade compaction, what is a reasonable sequence of compacted layer thicknesses when using a roller?
First layer 200 mm, next layers 150 mm
All layers 300 mm thick uniformly
First layer 100 mm, next layers 400 mm
Random thickness varying with moisture
What primary function does a granular subbase serve between subgrade and pavement?
Provide drainage and load distribution
Act as final riding surface
Increase soil plasticity and shrinkage
Replace the need for compaction
When specifying a granular subbase, which combination is most appropriate to control performance on site?
Select graded material, define layer count, set depth, require compaction
Use any local soil, omit layers, maximize depth, avoid compaction
Choose largest stones only, one thin layer, minimal depth, light rolling
Unspecified material, random layers, variable depth, visual settlement
Which statement best describes wet mix macadam used in road bases?
Crushed rock premixed with controlled water
Dense asphalt compacted without added water
Cement-treated soil mixed on the roadway
Graded sand layer sealed with prime coat

Hot mix with mechanized paver
Cold mix with manual raking
Warm mix with pneumatic roller
Hot spray with chip spreader
A contractor must choose the base course sequence before finishing by rolling. Which plan ensures a stable base and proper surface?
Place wet mix macadam, then bituminous macadam, finally roll
Roll subgrade first, place bituminous macadam, then wet mix
