Compaction of granular pavements using compaction equipment induces high stresses and strains in the materials being compacted. The distributions of these stresses are dependent on the properties of the compaction plant as well as the mechanical properties of the granular materials. The stresses help compact the granular materials at certain depths, but could also loosen the materials at some locations. Understanding of this micro behaviour of the granular materials is fundamental to improving the performance of granular pavements, and understanding and avoiding problems such as early rutting. The purpose of our investigations is to understand where, when and how the loosening may be happening, and consider measures that avoid this. To minimize early rutting, an innovative approach such as pre-stressing granular material will be tested.

Nilex Woven and High Strength Woven Geotextiles are often used for separation and stabilization in the construction of roads. The woven geotextile’s separation action prevents the mixing of dissimilar soils allowing each soil layer in the road structure to function as intended. The high tensile strength specifically associated with the high strength geotextiles provides the aforementioned function together with enhancing the low elongation properties over the standard woven geotextiles. This is done by imparting stability through the tension membrane effect into the road section reducing rutting and extending roadway life.
