The slab is supported on beams of size 225 x 500 mm spaced at 4.0 m centers. Design details are given in table 2, from which it is clearly evident that pavement thickness for a pavement structure designed as per IRC:37-2001 increased by 13% to 23.7% over the pavement design as per IRC:37-1984 primarily to account for the increased share of heavy axle loads and ensuring some certainty in pavement performance against . 0000006248 00000 n The site is a small commercial facility that hosts receptions and social events and therefore has a large number of parking spaces.
