Question

Which of the following is the correct order of stages of estimation of concrete roads?

(a) Earthwork excavations, cement concrete for the base course (1:4:8) and cement concrete for wearing course (1:2:8)

(b) Earthwork excavations, cement concrete for wearing course (1:4:8) and cement concrete for the base course (1:2:8)

(c) Earthwork excavations, cement concrete for the base course (1:6:9) and cement concrete for wearing course (1:7:9)

(d) Cement concrete for the base course (1:2:3), cement concrete for wearing course (2:7:9) and earthwork excavations

I had been asked this question by my school principal while I was bunking the class.

The question is from Labour and Rate Analysis in section Rate Analysis, Estimation and Costing of Construction & Building Materials

Answer 1

Right option is (a) Earthwork excavations, cement concrete for the base course (1:4:8) and cement concrete for wearing course (1:2:8)

To explain I would say: The correct order of stages of estimation of concrete roads is earth work excavations, cement concrete for the base course (1:4:8) and cement concrete for wearing course (1:2:8). Cement concrete road is laid over an existing Water Bound Macadam road.
