ASPHALT OVERVIEW
ASPHALT, also known as Asphaltum, is the most common variety of bitumen (also called mineral pitch). It is a compact, glassy, brittle, black or brown mineral. It is highly viscous liquid or semi-solid which is present in most crude petroleums and in some of the natural deposits. It breaks with a polished fracture, melts very easily giving a strong pitchy odor when heated, and leaves no ashes when pure asphalt is burnt.
Asphalt is sometimes confused with tar, coal tar, or pitch because the appearance is similar and the substances may be used interchangeably in many industrial processes. Tar and pitch are obtained from the coal products that are chemically and physically different.
ASPHALT Crushing and Screening
Screening and/or crushing may be required in some cases to produce a suitable aggregate like product from mill tailings or to meet gradation specifications. Crushing is not normally required, with the possible exception of some coarse tailings that may require size reduction of oversize particles. Some fine-sized tailings, such as copper mill tailings, can be classified prior to disposal in order to separate the coarser fraction of the tailings for subsequent reuse.
Types of Asphalt
Straight-run asphalt or asphalt cement - These are used for paving roads, airport runways, and packing lots. Since its nature is solid to semi-solid, it must first be cut with a solvent in order to bring it to a more liquid state. This process is known as Cut Back Asphalt. Highway workers mostly use straight run asphalt.
Air-blown or oxidized asphalt - It has a high softening point and is primarily used in roofing, pipe covering, and in other similar situations.
Mill Tailings
Mill tailings have successfully been used as aggregate in asphalt paving applications. Generally, the coarser, sand-size fractions of mill tailings can also be considered for use as coarse aggregates provided there are no harmful or reactive chemical components concentrated from the host rock and the tailings can satisfy the conventional paving aggregate requirements.
Despite the fine size of most mill tailings, these materials can be blended with coarser materials, such as gravel, to bring the overall fines content to an acceptable range. It is also possible to separate the coarser fraction of tailings by classifying prior to disposal.
Depending on the source of the mill tailings, there may be some concern with trace metals remaining after ore processing that could potentially leach from fine-grained tailings, which have a high surface area.
