Reclamation at Aggregate Mining Sites Fact Sheet 3 January

Aggregate mining is themon form of mining in Minnesota. Because aggregate is relatively inexpensive to mine but expensive to transport, most operations are located close to where the resource will be used. As a result, aggregate sites are found in every county and are highly visible along roadways.

A GIS Analysis to Evaluate Areas Suitable for Crushed

Aggregate is a low unit valuemodity. Costs to move aggregate from the mine site to the point of use is a large fraction of the resource cost to users. Production sites for aggregate occur where suitable source materials exist and where transportation and market conditions are favorable.

4 Aggregate Specifications and Requirements

If soundness testing cannot be conducted, the aggregate is required to originate from a Category I source in accordance with ITM 203. The total blended aggregate from the fine and coarse aggregates, and recycled materials used in HMA are required to meet the fine aggregate angularity FAA requirements of Section 904.02b. The procedure for

Aggregate sand and gravel has a myriad of uses, the most prominent of which are shown on the chart below. The main uses of sand and gravel aggregate in Michigan are in order: road base and coverings, concrete, fill to fill in low spots, asphalt, snow and ice control, and concrete products such as brick, block, pipe, and decorative stone.

Surface Mining For Construction Aggregates: Rock

Sources of constructione and go, but rock quarries and their associated products like sand and gravel have been around for centuries. Used in concrete, roads, landscaping, drain fields, fills, foundations, and even hourglasses, aggregate demand for sand and gravel has been a source of constant activity for surface mines and other quarries.
