Laboratory Batching Procedure Corrected for Fines and Moisture

摘要: A key step in mix design is the selection of an appropriate aggregate structure since this affects performance and amount asphalt mix. This paper explores effects that fines adhered to larger particles have on batch gradation resulting optimum binder content dust proportion. It shows conventional batching procedures can produce gradations with a substantially percent passing sieve No. 200 relative target gradation. procedure corrects for trapped moisture proposed shown replicate Asphalt was determined using superpave method both batched conventionally corrected procedure. volumetrics obtained cases are different. To obtain more-representative gradations, recommended routine specimens. Further research assess potential changes criteria tests.
