Systems and methods for resurfacing roads using road rejuvenator products
The disclosure provides a paving machine and related methods. In one example, a paving machine includes a first group of sprayers positioned on an underside of a body of the paving machine, and a second group of sprayers positioned downstream of the first group. The first group of sprayers dispense a first product on an existing road and the second group of sprayers dispense a second product over the first product. The paving machine includes a channel positioned downstream of the second group of sprayers to dispense an asphalt mixture over the second product, and a screed positioned adjacent to the channel in contact with the asphalt mixture.
1 . A paving machine, comprising:
a body including a front end, a back end positioned opposite the front end, and an underside extending between the front end and the back end;
a first group of sprayers positioned on or extending forward of the underside of the front end of the body, the first group of sprayers for dispensing a first product on an existing road;
a second group of sprayers positioned downstream of the first group of sprayers, the second group of sprayers for dispensing a second product over the first product dispensed by the first group of sprayers;
a channel positioned adjacent to and downstream of the second group of sprayers, the channel providing an asphalt mixture over the second product; and
a screed positioned adjacent the channel, the screed contacting the asphalt mixture provided by the channel.
2 . The paving machine of claim 1 , wherein the first group of sprayers is positioned downstream from the front end of the body.
3 . The paving machine of claim 1 , wherein the first product dispensed by the first group of sprayers includes a modifier, a liquid road rejuvenator product, or a mixture thereof.
4 . The paving machine of claim 1 , wherein the second product dispensed by the second group of sprayers includes an asphalt emulsion.
5 . The paving machine of claim 1 , wherein the asphalt mixture provided by the channel includes a hot mixture, a warm mixture, or a cold mixture.
6 . The paving machine of claim 1 , further comprising:
a hopper in communication with the channel, the hopper for receiving the asphalt mixture and providing the asphalt mixture to the channel.
7 . The paving machine of claim 1 , wherein the channel is positioned between the second group of sprayers and the screed.
8 . A system comprising:
a first group of sprayers positioned on or extending forward of an underside of a front end of a paving machine, the first group of sprayers for dispensing a first product on an existing road; and
the paving machine including:
a second group of sprayers positioned downstream of the front end of the body, the second group of sprayers for dispensing a second product over the first product dispensed by the first group of sprayers;
a channel positioned adjacent to and downstream of the second group of sprayers, the channel for providing an asphalt mixture over the second product; and
a screed positioned adjacent the channel, the screed contacting the asphalt mixture provided by the channel.
9 . The system of claim 8 , wherein the paving machine includes a spray machine including:
a storage tank containing the first product, the storage tank in communication with the first group of sprayers to provide the first product to the first group of sprayers.
10 . The system of claim 9 , further comprising:
a dump truck including a dump box, the dump box for storing the asphalt mixture and providing the asphalt mixture to the paving machine.
11 . The system of claim 8 , wherein the first product dispensed by the first group of sprayers includes a modifier, a liquid road rejuvenator product, or a combination thereof.
12 . The system of claim 8 , wherein the second product dispensed by the second group of sprayers includes an asphalt emulsion.
13 . The system of claim 8 , wherein the asphalt mixture provided by the channel includes a hot mixture, a warm mixture, or a cold mixture.
14 . The system of claim 8 , wherein the paving machine further includes:
a hopper in communication with the channel, the hopper for receiving the asphalt mixture and providing the asphalt mixture to the channel.
15 . The system of claim 8 , wherein the channel of the paving machine is positioned between the second group of sprayers and the screed.
16 . A method for resurfacing an existing road using a paving machine, the method comprising:
covering an exposed surface of the existing road with a first product;
covering the first product disposed over the exposed surface of the existing road with a second product,
wherein the first product dispensed by a first group of sprayers disposed on or extending forward of the underside of a front end of a body of the paving machine includes a modifier, a liquid road rejuvenator product, or a combination thereof, and
wherein the second product dispensed by a second group of sprayers includes an asphalt emulsion;
disposing an asphalt mixture directly over the second product; and
shaping the asphalt mixture disposed over the second product.
