Abstract
ABSTRACT This technical note presents the results of two static load tests performed in a root micropile installed in a tropical lateritic soil profile. The tests were executed 6 years apart in order to investigate for signs of ageing effects in the pile side shear resistance and load settlement behaviour. Despite the measurements indicated an increase in the side shear capacity of the first soil layer, the results did not show clear signs of ageing effects, which occurrence was analysed considering different mechanisms. Soil suction possibly contributes to the differences between the tests, which should be carefully monitored for future studies of ageing effects in piles installed in unsaturated tropical sites.
