Bazalt kullanımının aşınma tabakası performansı üzerindeki etkileri (Uşak-Kula yolu örneği)

Increase in traffic volume, tyre pressure, axle load cause serious deformations on highways and demand for new solutions to prevent these deformations. The causes of deformations can be classified in three main groups that are effect of traffic, effects of weathering and lack of adequate supporting capacity of base and sub-base course.Aggregates are one of the two main constituent of hot mix asphalt and composes 90-95% of it by weight. In this study the effect of basalt aggregate on the performance of wearing course is investigated.After the detailed examination of physical and chemical properties of mineral aggregates and types of bituminous binders, world-wide hot mix asphalt design methods has been explained.One of the major reasons of pavement deformation is the wrong action during field applications. In chapter four; field applications are explained starting from plant operations, transportation, surface preparation, mix placement till compaction to understand causes of failures and their effect to the performance of pavement.In the fifth chapter, types and causes of pavement deformation in hot mix asphalt and the rutting relation with aggregate are examined.Detailed experimental procedures are explained in chapter six. Four different Marshall mix design is prepared with basalt aggregate, mineral filler and limestone aggregate and the performance of mixes are investigated with rutting tests.
