Definitions
- a heated bituminous liquid is added to the combined ag- [5l] lnt.CI F26b 3/00 gregates in predetermined proportions, and the aggregates [50] Field of Search 34/9, 60; and bituminous liquid are mixed together to form a hot asphal- 263/1 tic composition.
- the typical procedure for creating the hot asphaltic or bituminous mix comprised storing graded lots of aggregate or a mixture of aggregate, mixing the graded aggregates togetheror blending the mixtures of aggregates in the approximate proportions that were to be ultimately mixed together, drying and heating the aggregates, elevating the dried aggregates through an elevator, screening the aggregates for separation into known sizes, combining predetermined quantities of known sizes of the aggregates together again and mixing the bituminous liquid with the aggregates, and storing or dispensing the bituminous mix into a vehicle for transporting to the construction site.
- the contractor was forced to initially combine different sized aggregates in order to properly heat them to economically dry and heat the aggregates, and after the heating step had been accomplished, the aggregates had to be separated or screened immediately before they were deposited into a batcher.
- This procedure required that the screening equipment be positioned vertically above the batcher, and that aggregate storage bins be positioned below the screening equipment, which created a relatively tall and expensive structure.
- the present invention comprises a bituminous mixing method and apparatus which dries and heats graded aggregate in separate lots, and combines the separate aggregates together immediately before placing the aggregates in a batcher or mixer.
- Another object of this invention is to provide a heating, drying, and conveying mechanism for use in a bituminous mixing process wherein aggregate can be conveyed separately from graded lots of aggregate, simultaneously heated and dried in varying quantities, and combined together as they are placed BRIEF DESCRIPTION OF THE DRAWINGS H6.
