Abstract
Methods of manufacturing hot mix on site utilizing a composition of discrete substances that are capable of being mixed together to form a composite material are disclosed. The composition includes a plurality of pellets of a tacky, deformable material at an ambient temperature dispersed within a flowable fine material. Stone aggregate is placed in a mixing chamber that has been moved within proximity of the location where the hot mix is to be used. At least a portion of the stone aggregate is heated in the mixing chamber to a temperature sufficient to soften the pellets of the tacky, deformable material. The composition of discrete substances is added into the mixing chamber. The mixture of the composition of discrete substances and the stone aggregate is agitated until the pellets of a tacky, deformable material soften and uniformly coat the stone aggregate.
