영문 초록

This paper describes a research study on the durability and strength properties of thin quiet-permeable asphalt concrete. Such asphalt mixes have high porosity, which offers significantly better drainages than normal mix designs. However, these materials also exhibit poor durability and strength limiting their use in pavement application. To remedy this, fiber and polymer modifiers have been proposed. All samples were added to modified binder which were prepared with or without the modifiers and fiber using Marshall mix procedures and were experimentally tested using various standardized testing procedures including percent air void for porosity, cantabro test and marshall stability. In general, the results of marshall stability showed that modified mixtures were equivalent to unmodified mixtures. Especially, the result of cantabro tested modified mixtures was superior to unmodified mixtures.
