THE EFFECT OF FABRICS ON PAVEMENT STRENGTH; PLATE BEARING TESTS IN THE LABORATORY

The Norwegian Road Research Laboratory has carried out a test program to investigate the effect of fabrics on pavement strength. Simulated road sections were constructed in the laboratory and consisted of one layer of subgrade material and one layer of gravel. Three different subgrade materials were tested each with three different gravel thicknesses. All sections were tested both with fabric between the layers and without. The plate bearing test did not show that the fabric has any influence on the load bearing capacity, however under certain conditions the fabric could cause the deformations to stop at failure pressure. The conclusion drawn from the tests is that the reinforcing effect of a non-woven fabric is of minor importance for the design of road pavements. The main explanation of the great success of the fabric is probably that the fabric prevents contamination of the subbase. /TRRL/
