A pavement is generally categorised by the type of material that is used to construct each of its individual layers.
A bound layer is created by either mixing cement powder, hydraulic road binder or lime with the unbound material [7]
‘Many practitioners feel that the integer programming-model is one of the most important models in management science’ [38].

Starting in the 1970 s, on the application of plasma technology in a lot of research on flue gas, from the initial electron beam method to later pulse corona technology, until today, a wide variety of discharge technology, a large number of useful results were obtained. 2.3.1 Electron beam irradiation (EBA) EBA process after the flue gas by electrostatic dust removal method, into the spray cooling tower, from the top of the tower ejected evaporates before fall to the bottom of cooling water vaporization, the flue gas cooled to near its saturation temperature60 ~ 70 (℃), and then the flue gas into the reactor, accepted by the electron beam of high energy electron accelerator 80×10-15~ 128×10-15( J) light, most of the electron beam energy is absorbed by the oxygen, nitrogen, water vapor in the flue gas, producing a large number of ions, free radicals, atoms, electrons, and various excited states of atoms, molecules, such as active material, they will be SO2 and NOx oxidation into

The major challenge for processing ores mined from high-arsenic deposit is the separation of copper arsenic, meanwhile, by pyrometallurgy treating high-arsenic sulfide copper concentrate may have a negative effect on environment due to the existence of arsenic, in addition, the usages of high-arsenic material are limited.
Material and Methods Sample The concentrate sample is taken from GeJiu in YunNan province of China, its constituent is shown in the table1.
