Summary: | Based on the comprehensive treatment project of Dagu Drainage River, this paper proposes the reutilizationof river sludge in roadbed filling to realize their recycling and harmless treatment and presents the first domestic classification standard of sludge utilization in accordance with relative state road and environment standards. The author carried out indoor tests and field construction tests of material performance after mixing sludge with lime, powder of building debris and lime slag respectively. These tests showed that all performance indexes of the sludge mixings meet the requirement of road specification, the limits of relative state standards and test requirements for heavy metals content and Extraction toxicity (ET). |
