Abstract
The aggregates for asphalt mix has to be selected from various stockpiles to match the specified gradation requirements. The fraction of various aggregates which give the desired aggregate gradation is very important to insure quality mix. Previously this fraction is determined by graphical and trial & error method. But due to present need, mix requires more sizes of aggregate which is not computable from these traditional methods. Many optimization techniques are now available which can be used for aggregate blending. These methods can seamlessly use to optimize the either specification requirement or cost minimization or both simultaneously. Here in this paper more scientific and mathematical optimization approaches are presented which can accurately answer these problems.
