There is still time to attend the Lightweight Fill Conference in virtual format! You can register at the conference website. As far as attendance goes, the registration fees are modest for attending, only $50. Proceeds will go to the ASCE G-I’s Student Fund – A very worthy cause!
Lightweight fill materials are materials that have a lower unit weight than the unit weight of locally available compacted natural soil fill. Lightweight fill materials that have been successfully used in civil engineering applications include expanded polystyrene, i.e., geofoam, cellular concrete, wood fiber, blast furnace slag, boiler slag, fly ash, shredded tires, foamed glass aggregate, expanded shale, clay & slate, pumice, and basalt.
