A sieve analysis (or gradation test) is a practice or procedure used in geology, civil engineering, [1] and chemical engineering [2] to assess the particle size distribution (also called gradation) of a granular material by allowing the material to pass through a series of sieves of progressively smaller mesh size and weighing the amount of material that is stopped by each sieve as a fraction ...
Among the construction trades, in most industrialized countries, each has a distinct 2-5 year craft apprenticeship education and usually once started a worker remains in a single craft and progresses through ranks of skill for the duration of their career (pre-apprentice, apprentice, and journeyman; some countries include a post-journeyman ...

The stone skeleton is filled with a mastic of bitumen and filler to which fibres are added to provide adequate stability of bitumen and to prevent drainage of binder during transport and placement. Typical SMA composition consists of 70−80% coarse aggregate, 8−12% filler, 6.0−7.0% binder, and 0.3 per cent fibre.
