Evaluation of blast efficiency in aggregate quarries: facts and
Primarily, in-situ rocks are drilled, blasted, loaded, and hauled to the crushing plant for further processes. The results of blasting have been proved to affect every other downstream process leading to the production of various aggregate sizes (Workman and Eloranta 2003; Kim 2010; Tosun and Konak 2015a). Thus, the need to evaluate the ...

The Aggregate Production Function
We now develop the theory behind the aggregate production function and establish these three properties in Propositions 1, 2, and 3. There are plant (or production unit) technologies for producing output. Plant technologies differ in the amount of capital k and labor n that is used by that plant. The output of a type (k, n) plant is y = fkn.

Chapter 2 Asphalt and Asphalt Paving Materials
The porosity of an aggregate permits the aggregate to absorb asphalt and form a bond between the particle and the asphalt. Adegree of porosity is desired, but aggregates that are highly absorbant are generally not used. 8.
