Best practices. Proper management of aggregate stockpiles requires many steps: “All the best practices in the world are not going to help you, if the asphalt or concrete plant you are selling the material to is not also using these best practices.
• ‘Aggregate’ is a term for any particulate material. It includes gravel, crushed stone, sand, slag, recycled concrete and geosynthetic aggregates. Aggregate may be natural, manufactured or recycled. • Aggregates make up some 60 -80% of the concrete mix. They provide compressive strength and bulk to concrete.
Chapter 3 presents best practices for sampling and testing stockpiled RAP materials. Chapter 4 discusses production concerns for mixes containing RAP. Chapter 5 provides additional guidance on best practices for handling Reclaimed Asphalt Shingles (RAS). This document represents the current best practices for RAP and RAS management
Solid wash out (aggregate and sand from original concrete) In order to achieve best practice concrete by-product management, used in the production of concrete may include: Fly Ash: Pulverised fuel ash (PFA) or fly ash from coal fired power stations can be used as a
aggregate by either adding various additives or changing its production methods. However, the industry is still behind in the wider use of recycled aggregate using such research findings. Hence, a research question was formulated as ‘what enablers and barriers affect utilisation of recycled aggregate concrete as a structural material?’.
This document contains recommendations for best practices related to the use of air-cooled blast furnace slag (ACBFS) as coarse aggregate in concrete pavements. It is primarily based on the results of a review of available literature regarding the production and use of ACBFS as coarse aggregate in concrete pavements,

Aggregate Stockpile Management 1. 13 By Mat Herron P roperly managing aggregate stockpiles means overcoming challenges both old and new, though drone technology is playing a greater role in solving those problems, experts say.
As noted earlier, the concrete may start to show signs of deterioration within a few years, or it may take more than 10 or 15 years to start exhibiting problems. For these reasons, avoiding the susceptible aggregate is the current recommended best practice to assure concrete durability.
