Describes studies made by the California Divi- sion of Highways in 1932 on internal vibration of concrete and subsequent application of the results of these studies in drafting specifications for and the placing of concrete in the San Francisco-Oak- land Bay Bridge, one of the earlier projects on which the internal type vibrator was used. Some of the essential requirements and advan- tages of internal vibration in concrete construction are discussed. The paper includes a brief descrip- tion of the 20 ft and 30 ft width pavement type vibrators used in placing and lower roadways of t e h and finishing the upper Bay Bridge.
