What is the most common waste material used in construction?

Detailed Solution for Test: Highway Materials & Testing- 1 - Question 5

Fly ash is an industrial waste obtained from the thermal plants, it has been mandatory to use the fly ash in bricks.

Test: Highway Materials & Testing- 1 - Question 6

Bitumen is a by-product of __________

Detailed Solution for Test: Highway Materials & Testing- 1 - Question 6

Bitumen is obtained by burning the petroleum at high temperatures, it is mostly used in the construction of flexible pavements.

Test: Highway Materials & Testing- 1 - Question 7

Tar is a by-product of __________

Detailed Solution for Test: Highway Materials & Testing- 1 - Question 7

 

It is a natural substance, oozing out of the ground in places like the La Brea tar pits. Usually it is made by heating coal inside a chemical apparatus. Most tar is produced from coal as a byproduct of coke production, but it can also be produced from petroleum, peat or wood.

Test: Highway Materials & Testing- 1 - Question 8

In the initial stage of construction which type of pavement is cheap?

Detailed Solution for Test: Highway Materials & Testing- 1 - Question 8

Flexible pavements are easy to construct and have cheaper cost than C. C pavements and also they are easily accessible to the users.

Test: Highway Materials & Testing- 1 - Question 9

What type of pavement can aggregate with an aggregate impact value of 26% not be used in?

Detailed Solution for Test: Highway Materials & Testing- 1 - Question 9

For the bituminous concrete surface course, the impact value should not exceed 24%, so the sample in the question cannot be used. For cement concrete base course, it must not exceed 45%, bitumen bound macadam base course 35% and for water bound macadam base course 40%.

Test: Highway Materials & Testing- 1 - Question 10

In a length gauge used for determination of elongation index, what is the length of gauge size for sieve sets 25 mm and 20 mm?

Detailed Solution for Test: Highway Materials & Testing- 1 - Question 10

The length of gauge size is obtained by multiplying the average of sieve sets with 1.8. So, for particles passing 25 mm sieve and retained on 20 mm sieve, the length of the gauge size would be
