GEOSYNTHETICS FOR THE IMPROVEMENT OF UNPAVED ROADS

Geosynthetics have been used successfully in the construction of unpaved roads. This paper presents the results from an experimental investigation into the effects of anchorage of three types of inclusion upon the rut depth observed under static loading. The model road comprised an anchored, or unanchored, geosynthetic at the interface between 200mm of well compacted road base overlying 500mm of soft clay. Rut depths observed above anchored inclusions were marginally less than those found in unanchored installations. The differences were less than could have been expected from conventional design methods. The principal conclusion derived from this study suggests that the expense of manually anchored installations may be unnecessary because sufficient load transfer and reinforcement takes place in unanchored situations over such subgrades. Comparisons with in-situ tests are drawn where possible. (A)
