LOADING TESTS ON PILES DRIVEN INTO ESTUARINE CLAYS AT THE PORT OF KHORRAMSHAHR, IRAN, AND OBSERVATIONS ON THE EFFECT OF BITUMEN COATINGS ON SHAFT BEARING CAPACITY
THE RESULTS OF 25 PILE LOADING TESTS ON CONCRETE, STEEL AND TIMBER PILES DRIVEN INTO DEEP ESTUARINE CLAYS AT THE PORT OF KHORRAMSHAHR, IRAN, ARE PRESENTED TOGETHER WITH DETAILS OF THE ASSOCIATED SITE INVESTIGATION. ABOUT HALF OF THE PILES TESTED HAD BEEN COATED WITH BITUMEN AS A PROTECTION AGAINST ATTACK BY SOIL ACIDS. THE BEARING CAPACITIES OF THE COATED PILES ARE VERY MUCH LOWER THAN THOSE OF SIMILAR UNTREATED PILES AND ARE MARKEDLY TEMPERATURE SENSITIVE. THESE FINDINGS ARE DISCUSSED IN THE LIGHT OF THE MECHANICAL PROPERTIES OF THE BITUMENS USED AND THEIR RELEVANCE IS INDICATED TO THE USE OF BITUMEN COATINGS IN REDUCING NEGATIVE FRICTION ON END BEARING PILES. /AUTHOR/
