If the modulus of sub-grade reaction of a standard plate with a diameter of 30 cm is 20 kg/cm³, the value of modulus of sub-grade reaction for a standard plate with a diameter of 75 cm is _____ kg/cm³.
Why are small angular aggregates used for highway pavement?
A bitumen sample has been graded as VG30 as per IS:73-2013. The ‘30’ in the grade means that
To determine the angularity number of an aggregate, the following observations were taken:
Weight of Empty Cylinder = 550 g
Weight of Cylinder + Aggregate = 2.75 kg
Weight of Cylinder + Water = 1.85 kg
Specific Gravity of Aggregate = 2.67
Calculate the angularity number of the aggregate.
In a Marshall Sample, the bulk specific gravity of mix and aggregates are 2.324 and 2.546 respectively. The sample includes 5% of bitumen (by total weight of mix) of specific gravity 1.10. The theoretical maximum specific gravity of mix is 2.441. The void filled with bitumen (VFB) in the Marshall sample (in%, up to two decimal places) is _______.
