Abstract:Full-automatic asphalt extractor, as a new asphalt extraction device, has been applied in test and detection items of road engineering widely. First, this paper introduces the technical principles of as-phalt extractor in light of extraction test determination technique of amount and grading of bituminous mix-ture. Then, it elaborates the main experimental processes and specific analytical methods for verifying amount and grading of asphalt combined with construction of the lower layer of the reconstruction product of the trunk line of Lianhuo Highway Huang-Ha Highway, which can provide reasonable references for relevant tests and detections.
Keywords:full-automatic extractor  amount of asphalt  grading  performance evaluation
