3. Section-1500
TABLE 1501.3: QUALITY CONTROL TESTS DURING CONSTRUCTION
S. No. Tests / Check Frequency
1. Subgrade & Subbase As in Tables 301.5 & 401.3
2. Gradation and moisture content of aggregate for
CC pavement
Minimum once per day.
3. Concrete workability (Slump cone tests IS:1199) One test per 3 cum of concrete at paving site.
4. Strength of Concrete (IS:516) Minimum 6 cubes and 6 beams (3 each for
7 day & 28 day strength) per day.
5. Straightness of side forms (steel)(For paralleling and
possible settlement and securing position before concreting)
To be checked daily
6. Size, spacing, paralleling of Dowel bars and location of To be checked prior to casting of concrete at
different joints the location.
7. Batching and Mixing of materials Check for measurements and proper mixing
8. Hot/Cold weather concreting including compaction Checks Regularly
9. Compaction equipment (Needle, Screed and Plate vibrators) For continuous working and stand by
arrangement
10. Separation membrane (thickness and laying) Prior to laying of pavement concrete
11. Levels and Alignment
(i) Level tolerance Clause 1802.3; to be checked for each day’s
work
(ii) Surface Regularity (Transverse and Longitudinal
including camber/cross slope)
Regularly
(iii) Width of pavement and position of paving edges
work Regularly at grid points
Clause 1802.2; to be checked for each day’s
(iv) Pavement thickness To be checked for each day’s work
(v) Alignment of joints -do-
(vi) Depth of Dowel Bars -do-
(vii) Texturing and Edging -do
