4. REQUIREMENTS FOR PLANTS CONTROLLING GRADATION OF HOT, DRY AGGREGATES 4.1 Plant Screens 4.1.1 Equip plants with plant screens having adequate capacity and size range to properly separate all of the aggregate into the sizes required for proportioning so that they may be recombined consistently within the specification limits.Gradation and Size - Pavement InteractiveThe particle size distribution, or gradation, of an aggregate is one of the most influential aggregate characteristics in determining how it will perform as a pavement material. In HMA, gradation helps determine almost every important property including stiffness, stability, durability, permeability, workability, fatigue resistance, frictional resistance and moisture susceptibility (Roberts et ...SIEVE ANALYSIS OF FINE AND COARSE AGGREGATES .to calculate relationships between various aggregate or aggregate blends, to check compliance with such blends, and to predict trends during production by plotting gradation curves graphically, to name just a few uses. Used in conjunction with other tests, the sieve analysis is a very good quality control and quality acceptance tool.

Section III: Surface Graveltons of aggregate are going to be purchased or crushed, is it not wise to invest a few hundred dollars in testing the material to insure that the right aggregate is used? It is a good practice to test the aggregate before placing it on the road.Also, if the tests fail, you can work with the crushing contractor to try to blend and improve or ...Cold Feed BinsAggregates are typically moved from the stockpiles to the cold feed bin using a front-end loader. Cold feed bins are used to accurately meter the different aggregates used in the mix to the drying drum. The amount of each aggregate is controlled by a combination of the gate opening at the bottom of the bin and conveyor belt speed.Marshall Mix Design - Pavement InteractiveOften, aggregates from more than one source or stockpile are used to obtain the final aggregate gradation used in a mix design. Trial blends of these different gradations are usually calculated until an acceptable final mix design gradation is achieved. Typical considerations for a trial blend include: All gradation specifications must be met.
