The ratio of longer span to shorter span is less than or equal to 2 it is two way slab
The ratio of longer span to shorter span is grater than 2 than it is one way.

Answer / srinu@

L/B Length of ratio is > 2 is 1 way slab
L/B Length of ratio is < 2 is 2 way slab

Answer / asad ali

(srinu@) ans is right but there words is wrong OK
L/B is span ratio not a (length of ratio) OK

Answer / shaikh altaf

if shorter span/longger span is greater 2 than two way slab
if shorter span/longer span is less than2 than one way.

Answer / sajin

if the ratio of length to breadth is less than 2 then its an
two way slab and if the ratio is greater than two then it is one way slab.

in one way slab design for the reinforcement ,the
reinforcement provided parallel to the shorter span will be
taking the load and called the main bar and the reinforcement
provided parallel to the longer side will be of smaller dia.
the bar in longer span is called distributer.the crank is only provided for the main bar (ie.bars parallel to shorter span)

in two way slab the reinforcement provided in both span will
be taking load and we have to provide crank for all bars

Answer / venky

One way slab is the slab having ratio of longer span to
shorter span equal to or more than 2 . If the ratio of
longer span to shorter span is equal to or less than 2, then
such slabs are called as two way slab.
In one way slab main tensile reinforcement is placed
parallel to shorter side which will be the main steel, where
as in two way slab both direction require main steel.

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.
