This study by Kief and Toan, published in Geotech Hanoi, surveys worldwide research, demonstrating that NPA Geocells improve layer modulus by up to x5 and reduce total costs of pavement construction by up to 20%. The study shows that NPA Geocells are a sustainable solution for the structural base of all roadway and railway applications. They also enable the utilization of on-site or recycled materials. Consequently, NPA Geocells can be used to meet affordable, sustainable construction goals in Vietnam and other rapidly developing countries.
