The grading of aggregate is studied primarily for the purpose of mix design. To choice the grading of aggregate is one of the important problems of mix design. The characteristic curve of aggregate grading may be described by the three parameters: maximum aggregate size, grading index and mineral filler content. In this paper we discussed the influence of the three parameters on aggregate continuously graded. Some new calculating formulas are established and successfully used in the asphalt mix design.
