Former BGA Chair, Professor David Toll, has contributed to the latest (22nd) ISSMGE Interactive Technical Talk (IITT) on Tropical Residual Soils (TC107) hosted by ISSMGE President Dr Marc Ballouz. Professor Toll talks about the particular difficulties associated with tropical soils, such as unusual mineralogy, cementation by iron and aluminium sesquioxides and the difficulties in testing and classifying such materials.
IITTs are a new educational initiative by the president of ISSMGE. They bring together geo professionals from around the world, young and renowned, from both academia and industry, to discuss a certain topic of geotechnical engineering. Other BGA members who have contributed are Professor Catherine O’Sullivan (Geo-Mechanics from Micro to Macro TC105) and Professor Mike Winter (Transportation Geotechnics TC202).
