difference between limit state method and working stress in
terms of load
Answer Posted / ghantola
Working Stress Method
The Stresses in an element is obtained from the working loads and compared with permissible stresses.
The method follows linear stress-strain behaviour of both the materials.
Modular ratio can be used to determine allowable stresses.
Material capabilities are under estimated to large extent. Factor of safety are used in working stress method.
The member is considered as working stress.
Ultimate load carrying capacity cannot be predicted accurately.
The main drawback of this method is that it results in an uneconomical section.
Limit State Method
The stresses are obtained from design loads and compared with design strength.
In this method, it follows linear strain relationship but not linear stress relationship (one of the major difference between the two methods of design).
The ultimate stresses of materials itself are used as allowable stresses.
The material capabilities are not under estimated as much as they are in working stress method. Partial safety factors are used in limit state method.

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.
