Prefabricated Vertical Drains to dissipate excess pore pressures during Dynamic Compaction of Clayey Sands with 30-45% Fines Content
ABSTRACT: A proposed Electric Vehicle (EV) assembling facility, located in the Eastern Seaboard of Thailand, required soil improvement to enhance the mechanical properties of the clayey sands (SC). Albeit not the ideal soils for energy densification, Dynamic Compaction (DC) + Prefabricated Vertical Drains (PVD's) were chosen as the most suitable Soil Improvement technique to increase the strength ...

Maximizing ice road open season and worker safety with real time temperature data
The Arctic region is facing an unprecedented crisis as temperatures soar nearly four times higher than in the rest of the world1. This warming trend has caused the operating window of ice and winter roads to shrink, leaving remote northern communities and industries with limited access to transport essential goods and resources during the winter months. A recent study found that a further rise ...

CPT cone selection
Introduction Cone selection is often not given much thought when selecting equipment for a Cone Penetration Testing (CPT) job. It is, however, quite important to consider the soil type that will be encountered as well as the investigation aims of the project. The CPT cone used can have huge impacts on the resulting data quality and applicability and should therefore be carefully considered. This ...
