Abstract

ABSTRACT: The paper presents the bearing ratio behavior of sand overlying silty sandy with two woven and two non-woven treated coir geotextiles at the interface under unsoaked and soaked condition. The chemicals such as sodium hydroxide and potassium permanganate were used to treat the coir geotextiles. The coir geotextiles were placed at two different locations (Designated as Series A and Series B). The results indicated that the bearing ratio of the sand overlying silty sand with untreated/ treated woven/non-woven coir geotextiles at the interface was higher in the unsoaked condition in comparison to soaked condition for the Series A and Series B. The improvement in the bearing ratio of the sand overlying silty sand with untreated/ treated woven/non-woven coir geotextiles at the interface in the unsoaked/soaked condition was higher for the Series A in comparison to the Series B. The bearing ratio of the sand overlying silty sand increased when the woven/non-woven coir geotextiles at the interface were treated with sodium hydroxide. The improvement in the bearing ratio of the sand overlying silty sand with potassium permanganate treated woven/non-woven coir geotextiles at the interface was higher in comparison to the sodium hydroxide treated woven/non-woven coir geotextiles. The highest improvement in the bearing ratio was achieved when both the woven/non-woven coir geotextiles were treated with sodium hydroxide followed by potassium permanganate.
