Abstract:
In order to explore the performance of road built with CVC solidified silts, through tests of dry shrinkage, anti-washout, freeze-thaw and splitting from three different silts, pavement performance with CVC solidified silts was deliberated, not only influence law of vermiculite content on dry shrinkage, but also effect regularity of vermiculite content on water resistance, freeze-thaw resistance and tensile properties. Road performance was evaluated by comparison with other curing agents' related properties. The results show that the dry shrinkage strain, average dry shrinkage coefficient, anti-erosion performance and freeze-thaw resistance will be improved with the increase of vermiculite content, however, the rate of water loss and splitting strength will be reduced. The organic matter in silts is harmful for anti-erosion performance, freeze-thaw resistance and tensile properties. 3 tabs, 10 figs, 12 refs.
