Abstract
A process and device for the recycling of asphalt including at least one one preheater unit. The preheater having a heater, scarifying rakes, and a bin to dispense aggregate. Also include is a recycling machine having a heater, scarifying rakes, a plurality of extension mills, a main mill, as well as a pug mill having first and second downwardly rotating rotors, the pug mill mixes asphalt and liquid additives together to form a homogenous mix; and at least one screed for laying the homogeneously mixed asphalt to grade.
Claims68
A process for the recycling of asphalt comprising:
- supplying at least one preheater unit, said preheater unit having a heater for heating an asphalt surface, scarifying rakes to scarify the heated surface and to release moisture contained in the asphalt, and a bin to dispense aggregate onto the heated and scarified asphalt surface;
- supplying a recycling machine, said machine having 1. a heater for maintaining the temperature of the preheated asphalt and aggregate, 2. scarifying rakes for applying a second scarifying application to the heated asphalt and to premix said aggregate and loosened asphalt, 3. a plurality of extension mills for milling said surface to grade, applying a second pre-mixing application of the asphalt and aggregate, a second moisture release from the asphalt, 4. a main mill for milling said surface to grade, applying a third mixing application of the asphalt and aggregate, a third moisture release from the asphalt using negative pressure and 5. a mainframe;
- adding a first application of rejuvenating fluid to the asphalt and aggregate at said main mill;
- supplying a pug mill having first and second downwardly rotating rotors, said pug mill mixes the asphalt and liquid additives together to form a homogenous mix;
- and at least one screed for laying the homogeneously mixed asphalt to grade.
An asphalt paving machine operable in both a paving and transportation mode comprising:
- a mainframe having a plurality of attachment points;
- a plurality of retractable wheels connected to and depending from said main frame;
- said rear attachment points adapted to engage an attachable transportation frame having at least one axle and corresponding wheels;
- a retractable stinger having a 5th wheel pin connector;
- in said transportation mode said stinger is in an extended position, said transportation frame is connected to said mainframe and said wheels are retracted;
- and
- in said paving mode, said stinger is retracted and said wheels are extended.
An asphalt paving machine operable in both a paving and transportation mode comprising:
- a mainframe having a plurality of attachment points;
- a plurality of retractable wheels connected to and depending from said mainframe;
- at least two of said attachment points adapted to engage an attachable transportation frame having at least one axle and corresponding wheels;
- a storage bin including a 5th wheel pin connector, said storage bin releasably attachable to at least two attachment points and positionable between raised and lowered positions;
- in said transportation mode said bin is in said raised position, said transportation frame is connected to said main frame and said wheels are retracted;
- and
- in said paving mode, said bin is in said lowered position and said wheels are extended.
