IX. Problems and Solutions
Random segregation consists of areas of coarse aggregate, sometimes referred to as "rock pockets", that occur randomly across the length and width of the mat. Random segregation is often a result of improper handling of the aggregates in the stockpile and cold-feed bins at the hot mix asphalt plant. Rock pockets or random segregation

behind the oxygen approach, where instead of air, the power plant is fed oxygen produced by an air separation plant. However, combustion with oxygen yields temperatures too large for today''s materials, so some flue gas must be recycled to moderate the temperature. Applying this process is easier for steam turbine plants than gas turbine plants.
Municipal Solid Waste Sorting Plant Project Report
Municipal Solid Waste Sorting Plant Project Report. Part 1. General description of waste sorting project. Waste is a kind of precious resource which is put in the wrong place, which has become a large trouble all over the world. Nowadays, as the peak of urbanization level comes, the municipal solid waste treatment problems have become more severe.
Stock Pile Segregation
· In concrete products, aggregate segregation can also lead to inconsistent feeds into the batch plant. If your gradations are too coarse, the concrete products can be hard to place and the strength can decrease. If the gradations are too fine, the shrinkage increases, water demand goes up, you need more cement, and/or the strength decreases.

Asphalt Segregation. DESCRIPTION Segregation is the separation of the course and fine aggregate particles in an asphalt mix. The segregation of the mix can occur at several locations during the mix production, hauling, and placing operation. Segregation can occur as the mix is delivered from the asphalt plant to a surge silo.
