Test: Highway Materials, Construction & Maintenance - Question 1

### In CBR test the value of CBR is calculated at

Detailed Solution for Test: Highway Materials, Construction & Maintenance - Question 1

In CBR test the value of CBR is calculated at both 2.5 mm and 5.0 mm penetration, Normally the CBR value at 2.5 mm penetration which is higher than that at 5.0 mm is reported as the CBR value of the material.

Test: Highway Materials, Construction & Maintenance - Question 2

### Percentage of free carbon in bitumen is

Test: Highway Materials, Construction & Maintenance - Question 3

### The ductility value of bitumen for suitability in road construction should not be less than

Detailed Solution for Test: Highway Materials, Construction & Maintenance - Question 3

Minimum ductility value of a normal bitumen should be greater than 50 cm.

Test: Highway Materials, Construction & Maintenance - Question 4

RC-2, MC-2 and SC-2 correspond to

Detailed Solution for Test: Highway Materials, Construction & Maintenance - Question 4

The cutback with the lowest viscosity is designated by numeral 0, such as RC-0, MC-0 and SC-0, suffix numerals 0, 1, 2, 3, 4 and 5 designate progressively thicker or more viscous cutbacks as the numbers increase. This number indicates a definite viscosity irrespective of the type of cutback; in other words, RC-2, MC-2 and SC-2 all have the same initial viscosity.

Test: Highway Materials, Construction & Maintenance - Question 9

The temperature to be maintained for the determination of the penetration value of bitumen is

Detailed Solution for Test: Highway Materials, Construction & Maintenance - Question 9

The penetration test determines the hardness or softness of bitumen by measuring the depth in tenths of a millimetre to which a standard loaded needle will penetrate vertically in five seconds. The sample is maintained at a temperature of 25°C.

Test: Highway Materials, Construction & Maintenance - Question 10

In highway pavements emulsions are mainly used in

Detailed Solution for Test: Highway Materials, Construction & Maintenance - Question 10

A bitumen emulsion is liquid product in which a substantial amount of bitumen is suspended in a finely divided condition in an aqueous medium and stabilized by means of one more suitable materials. The function of this emulsifier is to form a protective coating around the globules of binder resisting the coalescence of the globules.
