Explanation / Answer
a)Voids in total mix:
It is also known as air voids.It is the ratio of the volume of voids in a compacted mixture to the total compacted mixture volume.
b)Voids in the mineral aggregate:
It is void spaces between the aggregate particles of the compacted mix.
c)Voids filled with asphalt:
VFA is the voids in the compacted aggregate mass that are filled with asphalt cement
6.Batching is the measurement of different ingredients before mixing.
Batching are done in terms of volume or weight.
If batching is done in volume then it is called volume batching.
If batching is done in weight then it is called weigh batching and it is more preferable
