Certification Body: AITEX Textile Research Institute
Product certification reference: 2010GT0207
Objetive: The purpose of this test is to determine the variation in compression properties of the drainage geocomposite DRENOTUBE®, after an hydrolysis ageing. For this purpose, the results of compressive properties obtained from original samples (as 2010GT0206 report issued by AITEX), are compared with the obtained results of compressive properties of previously aged samples.
Test description: To carry out the test in both cases (original samples and hydrolsysis aged samples), the sample is placed in a semicircular base which has been made for this purpose. The compression is done with a hardened steel plate which compresses the sample vertically. The dimensions of this plate are 29 x 30 cm. To carry out the test, the sample has been compressed until its collapse. The ageing that has been applied to the samples has been 60º, 70º and 80º C for 28 days each one.
