Question

In general, the CBR values of 2.5mm penetration are smaller than 5mm penetration.

(a) True

(b) False

The question was asked during an online exam.

I'd like to ask this question from Flexible Pavement topic in portion Design of Flexible & Rigid Pavement of Geotechnical Engineering II

Answer 1

Right choice is (a) True

To elaborate: The CBR values are generally calculated for penetrations of 2.5 mm and 5 mm. Generally, the CBR values of 2.5mm penetration are greater than 5mm penetration. If the CBR values of 2.5mm penetration are smaller than 5mm penetration, then the test is repeated.
