Hand Compaction

One of the types of asphalt is called asphaltic concrete, which is made using continuous fractured aggregates and pure bitumen with a degree of penetration of between 60 and 100. There are several methods for producing asphalt concrete and asphalt planes, among which the following three most commonly used methods can be enumerated.

  • Marshall Method
  • Haberfield Method
  • Hveem (Gyratory) Method

All three of these methods have actually had satisfactory results, but what is most well-known in Iran is Marshall Method. Haber Field's method is most commonly used in asphalt concrete designs with a fairly fine aggregate, such as asphalt, in which materials of 100% of grade 4 grades are rejected. In the Hveem (Gyratory) Method, the asphalt samples are rubbed with rubbing, and the size of the largest asphalt beads is one inch as the Marshall Method. Marshall's method was first introduced by engineer Bruce Marshall, and later there were a lot of changes made until it became the current one. This method is described in detail in ASTM D1559.

The samples prepared by Marshall in order to find the relationship between density and the percentage of bitumen, to gain the relationship between specific gravity and bitumen percentage and the relationship between the percentage of bitumen and empty space, compressive strength and drawing the related charts, and also used for indirectly cutting of asphalt.
