| Summary: | Aggregate type and grading play an important part in the performance of asphalt mixtures having an effect on stability, impermeability, surface degradation, skid resistance, fatigue life and segregation. Aggregates may be broadly characterised by rock type, as natural uncrushed rocks and sands or crushed materials. This exprimental project attempts to study the effect of different aggregate type and gradation on the properties of the bituminous mix of road pavements and to determine the optimum bitumen content based on the Marshall Stability test method. Two types of aggregates; namely granite and limestone were used with different gradation i.e. gap graded, well graded and uniformly graded. |
