Investigation of Engineering Performance of Gravels mixed with additives for unsealed pavement stabilization.

摘要

A case study was undertaken to assist Central Goldfields Shire Council, Victoria, Australia, inrnassessing the success of its unsealed road stabilisation program. A section of road was treated inrn2009, with different combination of additives (RT20 and Eko-Soil) and then post construction testingrnwas carried out in 2010 to verify the success of the trial. A set of parameters, including CaliforniarnBearing Ratio (CBR), Unconfined Compressive Strength (UCS), Maximum Dry Density (MDD), andrnOptimum moisture content was tested after the setting of the additives. The results indicated thatrnEko-Soil performed better than Reynolds RT-20 in treating the selected site.
