Abstract: |
In this study, preliminary results of zeolite application to reduce the compaction temperature of mix asphalt are presented and discussed. The reference mix was an asphalt concrete AC 16 W containing 35/50 penetration grade bitumen and designed for binder course. Two types of the zeolites were used for tests: natural zeolite klinoptilolit and synthetic NaP1 one. The optimal amount of zeolite addition was determined on the basis of the compactibility test results in the Marshall compactor as well as in the gyratory compactor. The results of stiffness modulus and waterproofness tests confirm the possibility to reduce the compaction temperature of asphalt mixes with zeolite additions to 1300C level. |
