Une machine de haute qualité pour le test d’indentation avec logiciel avancé pour l’acquisition automatique des données, enregistrer et présenter les résultats au travers de graphiques en temps réel

PRIMA100 Light Weight Deflectometer (LWD) is the LIGHTER field measuring equipment with state-of-the-art technology based on more than 30 years of experience of development and production of large scale equipment.

This portable and practical equipment is the answer to on-site measurement of bearing capacity for on-site measurement of bearing capacity, thus minimizing risk and optimizing quality.

Using the portable falling weight deflectometer, PRIMA 100, is the quickest, easiest and most safe way to determine bearing capacity and assure unbound layer quality. PRIMA 100 measures the surface modulus and presents the results immediately allowing decisions to be made on site.

Professor Collop and co-workers of University of Nottingham in the early part of this decade. The test is a combined ageing/ moisture sensitivity test to evaluate the performance of macadam coated binder course and base mixtures.  

The test involves the position of core samples in a high pressure (21 bar air) and high temperature (85°C) environment for 4 days to prematurely age the sample. These samples are then tested in the Nottingham Asphalt Tester/ NU14 to measure the tensile strength of the core samples.

This test has been adopted by the Highways Agency as a compulsory QC test method for any asphalt that is supplied to them.  This requirement came into force in Autumn 2007.

Due to the high pressures that are used in this test, the equipment must be constructed in a suitable fashion.  This equipment is used by a number of leading asphalt suppliers in the UK.
