Compaction characteristic of the surface layer asphalt mixture (13-type gradation mixture) was studied using Superpave gyratory compactor (SGC) simulative compaction tests. Based on analysis of densification curve of gyratory compaction, influence rules of the contents of mineral aggregates of all sizes and asphalt on compaction characteristic of asphalt mixtures were obtained. SGC Tests show t...

Compaction is one of the most important factors to be considered while manufacturing laboratory samples cold in-place recycled (CIR) mixtures. In this study, effect three compaction procedures (static, gyratory, and impact) on volumetric performance CIR mixtures was investigated. specimens were manufactured with same proportion added water bitumen emulsion, using several levels compaction, vary...

Filler and binder make up a small proportion of bituminous mixtures, hence they are considered as important ingredients mixtures. Sometimes due to equipment error during production, some mixtures retain extra or reduced amount filler compared the design mix formula. It is thought that poor performance result inadequate proportioning materials use inappropriate compaction tools. This study was i...
