Sample Checklist for Inspection of Road works

Road Pavement Construction Inspection Checklist

Below is a sample checklist for inspection of road works which you can use for doing the inspection of road works.

Stage of work/Item Technical Parameters to be checked / ensured As per estimate At Site
 

 

 

 

 

 

Geometrics (verify irrespective of stage of work)

To check and ensure the following

a) Length

b) Roadway width ( 6.00m/7.50m)
c) Carriage way width (3.00m /3.75m)
d) Shoulder width (1.875m /1.50m)
e) CC pavement width
 

f) Camber of shoulders and embankment

( Range- 4 to 5% in case of Earthen road, 3.5 % to 4% in case of Gravel/WBM surface and 3 to 3.5% in case of BT surface)
