PORTABLE PAVING MATERIAL MIXING APPARATUS
First Claim
1. A portable paving material mixing apparatus configured to prepare aggregate for repairing a paved surface, the apparatus cooperating with a vehicle trailer, the apparatus comprising:
- a hopper having an open top configured to receive aggregate and being positionable to transfer a portion of the aggregate to a rotatable mixing drum through an aperture in a front end of the drum;
a burner configured to heat material within the mixing drum;
a discharge bed positioned to receive mixed paving material from the mixing drum and configured for direct transfer of the mixed paving material to the paved surface; and
,the hopper, mixing drum, and discharge bed configured to be simultaneously supported on the vehicle trailer.

Abstract
A portable paving material mixing apparatus includes a material hopper, a rotatable mixing drum, and a discharge bed, all configured to be supported on a vehicle trailer. A burner heats material within the mixing drum. Embodiments of the mixing apparatus include a rejuvenator application system suitable for hot mix asphalt, cold mix asphalt, hot in-place recycling, and asphalt based concrete mixing. The apparatus rapidly processes a batch of material sufficient to fill 5-7 potholes, has sufficient carrying capacity to process multiple mixer batches, and stores prepared material in the discharge bed while the next batch is being prepared in the mixing drum. The apparatus enables a more efficient, less equipment-intensive paving repair process without the need for a separate millings loader or hot box.

16. A method for preparing paving material to repairing a paved surface, the method comprising:
-
a. providing a portable paving material mixing apparatus including; i. a vehicle trailer; ii. a hopper having an open top configured to receive aggregate and being positionable to transfer a portion of the aggregate to a rotatable mixing drum through an aperture in a front end of the drum; iii. a burner configured to heat material within the mixing drum; iv. the drum having an access panel in a sidewall through which material may exit the mixing drum to be received in a discharge bed; v. the discharge bed positioned to receive mixed paving material from the mixing drum and configured for direct transfer of the mixed paving material to the paved surface; and
,vi. the hopper, mixing drum, and discharge bed supported on the vehicle trailer; b. providing aggregate; c. loading the aggregate into the hopper; d. positioning the hopper to transfer an appropriate amount of aggregate from the hopper to the drum and returning the hopper to a resting position; e. rotating the drum to force aggregate toward a rear end of the drum; f. operating the burner so that a flame projects into the drum but does not come in direct contact with material in the drum, for a period of time sufficient to heat the material to a predetermined application temperature; g. rotating the drum while the burner is on; h. stopping rotation of the drum and opening the access panel; i. rotating the drum to discharge material from the drum to the discharge bed; and
,j. moving material from the discharge bed to the paving surface. - View Dependent Claims (17, 18, 19, 20)
