Conducting 7 days-24 hours (24 x 7) traffic survay using mobile automatic traffic count and classifier (ATCC) in both up & down direction for determination of 'PCU', 'CVPD' and other relievant traffic parameters required for pavement design as per relevant IRC codes at any suitable location over the road.

Conducting axle load survey for determination of VDF as per relivant IRC code at any suitable location over the road.

Conducting Falling Weight Deflectometer (FWD) test for overlay design of pavement as per required frequency on the entire stretch of the road conforming to relevant IRC guide lines.

Assessment of existing pavement layers of the road by making pits of suitable dimension @ 2 Nos/Km (zigzag way) with making still and video photographs of the same, collecting soil sample from the pits to determine the different soil properties of the sub-grade soil, like –LL, PL, PI, CBR, Soil Classification, Sieve Analysis, Sand Content, Modified Proctor Test, FSI etc. as per relevant IS codes.
