Application of Settlement Observation Method Combined with Water Replacement Method in the Controlling the Construction Quality of Mixing Soil and Stone Material

At present, conventional techniques that applied to test the earth compactness such as sand replacement method, cutting ring method and nucleon density instrument are not applicable to control the roller compaction quality of the earth-rock mixtures. In this article, comparison of settlement observation method to water replacement method is analyzed. Process test of roller compaction is carried out in the engineering. Then settlement observation method combined with water replacement method is presented to control the roller compaction quality of the earth-rock mixtures. The result shows that the settlement observation method combined with water replacement method is easy, true and reliable. It is available to control the construction quality and provide referring to the similar engineering.
