چکیده انگلیسی
This paper discusses the behaviour of field-stabilized bored pile mud and the feasibility of its application in pavement. The geotechnical properties of field-stabilized mud on different curing days were evaluated by a series of laboratory tests including compaction, California Bearing Ratio (CBR), modified unconfined compressive strength (MUCS), axial compression tests and scanning electron microscopy (SEM). A field roadbed 80â¯cm thick and 50â¯m long was paved successfully using the in-situ stabilized mud treated by the proposed in-situ stabilization system. The stabilized mud displayed a favourable fill performance in regards to the compactness and deflection values of the test pavement. Maximum dry density for improved mud increased while optimum water content decreased over time. A linear relationship between CBR and curing time was identified. The main role of fly ash (FA) is filling void in stabilized mud rather than reacting with other parts.
