The Influence of Bituminous Coating on Uplift Resistance of Short Pile Foundations in Sand

Abstract

Bituminous coatings can be used to reduce negative skin friction on pile. The present study investigates the other applications and the effectiveness of heated coating withelastic and visco-elastic-plastic behavior on the skin friction at soil-pile interface. Aseries of small scale physical modeling tests of short pile foundations under pullout load was carried out to study the effects of adhesive coating materials on the short pile foundation interaction. The results indicated that heated bituminous materials can significantly affect the pull-out capacity of short pile foundations.
