Flexible pavements and rigid pavements are two types of roads.
Flexible pavements have an embankment thickness of 3m and large size soil particles.
Rigid pavements are made of concrete or asphalt and have a rigid structure.
Flexible pavements are more suitable for areas with high traffic loads and varying soil conditions.
Rigid pavements are more durable and require less maintenance compared to flexible pavements.

Discussion on DLC mix using M15 grade concrete and 12:1 aggregate cement ratio.
Minimum cement content is 120 kg per cum if flyash is more than 20%.
5 samples of cube tested for 7 days with 10MPa compressive strength.
DLC mix is homogeneous and uniform in pre mix batching plant.
DLC is carried from one place to another place covered by tarpoline.
One sample after 7 days showed 7.5 Mpa compressive strength.
The question is unclear and lacks context.
The question needs to be rephrased for clarity.
More information is needed to provide a proper answer.
It is unclear what the purpose of the DLC surfaces is.
The sub base surface compaction percentages are not relevant to the question.
The question may be related to civil engineering or construction.
The question pertains to the expected stress and restrained movement on an expansion joint with dowel bar load transfer.
Total thickness of 300mm with M40 grade concrete and 31.5mm aggregate size.
Texture strength of cement concrete is 4.5 Mpa and compressive strength after 28 days curing is 40Mpa.
Expansion joint thickness is 25mm with dowel bar load transfer to one slab to another slab.
Dowel bar is 32mm dia, 500mm lengt...

The interviewer is asking about CBR valve and subgrade for road construction.
CBR valve is generally between 3 to 15% for road construction
Clay content should be less than 8%
Sand content should be between 15% to 35%
Gravel content should be greater than 25%
CBR division of state highway develops CBR
Subgrade and aggregate should meet the CBR valve requirements
