Curing has a major influence on the properties of hardened
concrete such as durability, strength, water-tightness,
wear resistance, volume stability, and resistance to
freezing and thawing
Proper concrete curing for agricultural and residential
applications involves keeping newly placed concrete moist
and avoiding temperature extremes for at least three days.
A seven-day (or longer) curing time is recommended.
Begin the curing as soon as the concrete has hardened
sufficiently to avoid erosion or other damage to the freshly
finished surface.
This is usually within one to two hours after placement
and finishing.
Keep water on the concrete during the curing
period. These include
ponding or immersion,
spraying or fogging, and
saturated wet coverings.
Such methods provide some cooling through
evaporation, which is beneficial in hot weather.
Prevent the loss of the mixing water from
concrete by sealing the surface. Can be done by:
covering the concrete with impervious paper or
plastic sheets,
applying membrane-forming curing compounds

As per Kandal suggestions, we have implemented rolling starts on 140 (+/- 5) degrees and we kept 3 rollars to complete the rolling before falling 125 degrees and the Aggregate AIV is below 22. But When the DBM bed is being rolled 3rd high viabration, (Before 1 plain & low ,2 high Viabrations), the aggregate is getting sharp edge agg. projections are damaged. As the literature is said that, the VG-30 Grade having better control the temp. susceptibility than Penetration grade. if so we could not get this problem at site. But we are facing on site. let me know.
