Resource Characteristics of Weathered Rock Aggregates and Feasibility Evaluation for Using as Roadbase
Focusing on the waste slag in four sections along the first-phase engineering of Three Major Tourist Highways in Pianguan County,Xinzhou City,Shanxi Province,this paper analyzed the resource characteristics from three aspects of weathering degree determination,engineering characteristics of the mother rock of the waste slag,and engineering characteristics of weathered rock aggregates.Regarding the technical requirements from the implementation handbook Technical Guidelines for Construction of Highway Roadbase as the criteria for determination,the feasibility of using the waste slag as the roadbase was evaluated.The test results showed that for the mother rock of waste slag and crushed aggregates along the engineering,the parameter indexes of engineering characteristics met the specification requirements of the use as the roadbase(subbase);the optimized gradation of the crushed mixture could meet the requirements of the gradation curve,and it could be applied to the secondary or below highway roadbase(subbase).
