|I think Kelly's formula is right.|
|Dhanu said: (Sep 18, 2017)|
|Yes its Kelly's formula.|
|Roy said: (Oct 3, 2017)|
|Kelly for edge loading, picket for corner loading and Westergaard for internal loading.|
|Shashikanth said: (Oct 28, 2017)|
|For edge loading Teller and Sutherland formula.|
|Ashu said: (May 28, 2018)|
|Yes, Correct @Roy.|
|Sam said: (Aug 5, 2018)|
|Glodbecks also used for corner loading.|
|Koamala Sai Kumar said: (Dec 23, 2018)|
|The formula for corner loading was first proposed by Westergaard and later is modified by Teller and Sutherland.|
|Swar said: (Jan 11, 2019)|
|I too think its Kelly's formula.|
|Aadarsh said: (Jan 14, 2019)|
|Option A. Westergaad's formula (as per IRC 58-2011).|
|Neeraj Kumar said: (May 16, 2019)|
|Option A and B both are correct because the formula was given by Westergard but slightly modified by Kelly later.|

|Westergard gave a formula for three Loading cases-Corner, Edge and Interior. Kelly modified Westergard's corner loading equation for more accuracy and it is now being used by IRC.
Original corner loading formula was given by Gold beck but was latter found to give stresses under wheel loads considerably higher than actual stresses in pavement slabs under service conditions.
PICKETT (along with Ray) gave influence chart for determining stress at interior and edge of the pavement.
