Abstract

The invention disclosed herein pertains to a device for repaving an existing asphalt surface, specifically a road surface. The device enables continuous uninterrupted excavation and removal of old road paving material. Said device further extracts the excavated material for milling into smaller evenly sized aggregate material that is sorted through by size, retreated under heated conditions with the addition of hot oil, and further homogenized for even size, density, and saturation before being relayed over the extracted surface.

1 . A road paving device comprising at least three wheeled carriages wherein at least one of said three wheeled carriages having a motorized engine, said at least three wheeled carriages movable in tandem together in a linear direction, a first wheeled carriage having a container and an extraction element whereby pulverized and loosened asphalt material from the ground surface is pulled into its said container, an elevator system is disposed within the container of said first wheeled carriage, said elevator system is angled in an upward position towards a second wheeled carriage, an L-shaped platform containing a rotatable drum is positioned between the first and second wheeled carriage along their adjacent top surfaces, said second wheeled carriage having a container wherein said container comprises three segmented spaces, a first segmented space containing a series of pans extending laterally from the internal vertical wall surface of said container, each pan is slanted at a downward angle, said pans are positioned in opposite and alternating manner from each other along opposing vertical side surfaces of said first segmented space, each pan is attached to an agitator element that, when initiated, will cause each said pan to shake and agitate, an escalator element is positioned within a second segmented space, said escalator element is movable in an upward direction towards the top side of said third segmented space, said third segmented space of said second individual wheeled carriage containing at least three augers, each auger of said at least three augers extending along and parallel with the length of said third segmented space and parallel with each other, said third segmented space contains a conveyor platform positioned adjacently to said third wheeled carriage, said third-wheeled carriage having a container along its top side.

BACKGROUND OF THE INVENTION Field of the Invention The invention herein pertains to a device for repaving an asphalt ground surface. Background Advancement of technology relating to the rehabilitation of roads now allows for on-sight removal, rehabilitation, and reuse of aged asphalt pavement material. Current types of asphalt material used for road rehabilitation comprise the following: Hot Asphalt, MC Cold Asphalt, and UPM. The inherent nature of these types of asphalt material will determine paving methods. Hot Asphalt is a common type of asphalt used for paving and patching. As the name suggests, Hot Asphalt, is easiest to work with when the temperature of the asphalt is high. Hot Asphalt is longer lasting and offers permanent solution to road condition problems. However, it must be used almost immediately after purchasing. As the asphalt cools, it becomes increasingly difficult to work with, and once completely cool, it hardens like rock. MC Cold Mix is asphalt that can be used as a temporary solution. Since this type of asphalt is used at cold temperatures, it is slow to cure and best used in areas that have little to no traffic to avoid deformities from untimely impact. UPM is also a cold mix asphalt, but unlike MC Cold Mix, it can be used as a permanent solution to any asphalt or concrete problem. UPM is designed to work in any weather condition and can be used to fix both wet and dry holes. Once UPM has been compacted, it is immediately ready to be tread upon. The focus of this invention relates to on-site recycling and reuse of hot asphalt material. U.S. Pat. No. 4,534,674 relates to a method and system for recycling and reuse of hot asphalt pavement material. U.S. Pat. No. 4,534,674 discloses a road resurfacing machine comprising a vehicle having a heating element positioned underneath a chassis wherein said heating element directly heats and melts the road surface. The melted state of the road surface renders it more malleable for scarification. By this invention, the road is excavated and crushed on-site to produce coarse rubble, hot asphalt cut-back oil is sprayed directly onto the coarse rubble to rehabilitate and bind the asphalt, new hot asphalt material is added atop the excavated rehabilitated material and mixed in commingling manner in-situ, then compacted by said vehicle. A problem remains whereby the device lacks the ability to homogenize the size, the density distribution, and the evenness of coated oil over the excavated aggregate material, which affects the life-span of the pavement. U.S. Pat. No. 12,734,584 discloses a similar method of in-situ hot asphalt resurfacing that also lacks a means to homogenize the excavated material. There currently remains a need within the industry for improved quality of recycled hot-asphalt material for in-place repair wherein the rehabilitated asphalt material is more homogeneous in size, distribution, and saturation. SUMMARY OF THE INVENTION The invention disclosed herein pertains to a device for repaving an existing asphalt surface, specifically a road surface. The device enables continuous uninterrupted excavation and removal of old road paving material. Said device further extracts the excavated material for milling into smaller evenly sized aggregate material that is sorted through by size, retreated under heated conditions with the addition of hot oil, and further homogenized for even size, density, and saturation before being relayed over the extracted surface. It is an objective of this invention for the device of this invention comprises a series of interconnected wheeled carriages that are connected by a single motorized engine. It is another objective of this invention for the device to comprise a series of interconnected wheeled carriages move tandemly together in a linear direction. It is another objective of this invention that the device enables milling of excavated asphalt material into relatively similar-sized stones, and for the mixture of said milled stones to be evenly coated with hot oil, and to be mixed into a relatively homogenous texture and or density. It is yet another objective of this i
