Skin Friction of Piles Coated with Bituminous Coats
Piles are often coated with a slip layer such as bitumen to reduce the dragload. The friction between granular soil and coated as well as uncoated pile surfaces were studied using a modified direct shear test apparatus. The lower half of the direct shear box was replaced with a concrete or mild steel block to represent a pile surface. Two types of bituminous coat namely Shalikote and Bitumen of grade 30–40 were evaluated in this study. Shalikote and Bitumen coating reduced the interface friction by more than 70% and 90% respectively. The shearing resistance of pile material-coat-soil is found to be influenced by normal stress, type of coat, and coat thickness. The effect of saturation and the rate of soil settlement on the interface friction are also discussed. Pull out tests were carried out on coated and uncoated model aluminum pile placed in a circular tank filled with granular soil. The results of pull out tests are compared with interface friction tests.
