5 Aggregate Production - IN.gov

This chapter discusses the total process of aggregate production from extraction through processing. Also discussed is the handling, stockpiling, and shipping of the product up to the point where the material leaves the Producer's control. Processing influences mineral quality and integrity, aggregate physical properties, and, in particular, gradation (size control). Establishing a stable ...

How is Asphalt Made? A Look Inside the Manufacturing Process

26/09/2018  Aggregate varies depending on climate and other requirements. Essentially, you could define it as a bunch of small rocks. On the lower sections of a pavement, the aggregate comprises of larger and smoother rocks. At the surface level, however, the aggregate is finer and more course. Other additives may be included to improve the final product ...
