Durability Capacity Change of Rubber Powder Composite BRA Modified Asphalt Mixture

Both engineering practice and literature confirm that the high modulus asphalt mixture has superior performance. If modified, final can effectively improve service life of pavement. Therefore, design test this paper are trying to mix rubber powder BRA prepare Sup-13 mixture. Through a series experimental studies, discusses effect adding separately both into on its durability. The part mainly focuses composite modified water resistance test, temperature stability low crack it is concluded compound modification equalize improvement strength, modulus, strain. For reason, if with finer particle size adopted modify mixture, specimen will apparently.
