Recycled Technology of Urban Road Construction Waste and Miscellaneous Fill Used as Subgrade Fillings

Abstract:

Article Preview

Continuously increasing municipal renovation and roadbed excavation produced a considerable quantity of solid waste each year such us miscellaneous fill mixed with broken pavement fragments and brickbats, which resulted in a series of urban environment and soil resource issues. Comprehensive recycling technology for soil modification to attain the strength requirements of subgrade fillings from the related road construction codes is necessary and even urgent, since the usual soil replacement is not the economic and environment-friendly method. The field investigation and laboratorial tests hereby had been completed to confirm the application potentials of typical soil specimens selected from different locations. The experimental results indicate some of specimens can be reused as subgrade fillings in road construction immediately and others should be treated by soil amelioration. To further certify the practicality of this recycled technology and broaden its range of application, three typical reutilization and treatment techniques, cold recycling, soil solidification and dynamic consolidation are introduced into engineering projects.
