System and method for asphalt mix tracking
An asphalt mix tracking system having a data collection system adapted to determine at least one characteristic of the asphalt mix, a data control system adapted to receive data from the data collection system, a lot tracking system adapted to track a lot of the asphalt mix, a truck tracking system adapted to track a truck, and a pavement injection system adapted to identify the lot of the asphalt mix. The preferred asphalt mix tracking system is adapted to substantially continuously track the asphalt mix from a mixing site to a paving site. A method for tracking an asphalt mix including determining the at least one characteristic of the asphalt mix, communicating the at least one characteristic of the asphalt mix to the data control system, transporting the asphalt mix from the mixing site to the paving site, and injecting an identification means at the paving site.
1. A method of making data relating to asphalt mix available at a paving site where said asphalt mix has been used to form a section of pavement, the method comprising the steps of:
(a) providing a tracking system that is configured to collect data related to the asphalt mix;
(b) depositing one or more tags into the asphalt mix, each tag provided with a first set of data related to the asphalt mix into which it is deposited;
(c) collecting and storing a second set of data related to the asphalt mix using the tracking system;
(d) associating the first set of data with the corresponding second set of data in the tracking system;
(e) depositing the asphalt mix at the paving site and forming the section of pavement;
(f) after the section of pavement is formed, retrieving the first set of data from one of the tags in response to wireless interrogation by a reader;
(g) wirelessly transmitting the first set of data sent from the one tag to the tracking system;
(h) wirelessly receiving second set of data that is sent from the tracking system in response to the tracking system receiving the first set of data,
wherein a first one or more tags are deposited into the asphalt mix at a mixing site at irregular intervals upon at least one of a determination of an out-of-specification asphalt mix and a determination that the asphalt mix has returned to within specification and a second one or more tags are deposited into the asphalt mix at the paving site.
2. The method of claim 1 wherein the second set of data is at least one of: the name of the formula of the asphalt mix; alarm conditions present or occurring during the mixing process of the asphalt mix; the name, weight, percentage flow rate of ingredients of the asphalt mix; lot size; start or stop times of mixing; duration of mixing; or an instantaneous or average temperature of asphalt mix.
3. The method of claim 1 wherein the second set of data is at least one of: total transit time for transporting the asphalt mix from the mixing site to the paving site; time the asphalt mix is located at the mixing site; transit time between a bin and the mixing site; or transit time between the mixing site and a silo.
4. The method of claim 1 further comprising providing a truck tracking system configured to track one or more vehicles conveying a lot of asphalt mix from a mixing site to the paving site, and providing at least one of location information and transit time information from the truck tracking system to the data control system, wherein the data control system is configured to associate the data received from the truck tracking system with the lot of asphalt mix transferred to the paving site.
5. The method of claim 1 wherein the second set of data is stored by the data control system to a server.
6. The method of claim 1 , wherein the one or more tags are deposited into the asphalt mix at irregular intervals.
7. The method of claim 1 , wherein the one or more tags are deposited into the asphalt mix at regular intervals.
8. The method of claim 1 , wherein the first one or more tags identify a portion of asphalt mix that is out-of-specification, the method further comprising removing the out-of-specification portion of the asphalt mix prior to depositing the asphalt mix at the paving site and forming the section of pavement.
9. The method of claim 1 wherein the one or more tags are deposited into the asphalt mix at the paving site by a paving site dispenser after the asphalt material is deposited but before the asphalt mix hardens to pavement.
10. The method of claim 1 wherein the one or more tags are deposited into the asphalt mix at a mixing site.
11. The method of claim 1 further comprising wirelessly retrieving the stored data from the one or more tags using a reader carried by a vehicle traveling over the section of pavement.
12. The method of claim 1 wherein the data collected by the tracking system includes at least one non-location characteristic.
13. The method of claim 1 wherein the data is collected before the asphalt mix is deposited at the paving site.
14. The method of claim 1 wherein the second set of data received at step (h) is received by the reader.
15. The method of claim 1 wherein the second set of data received at step (h) is received by a wireless device that is not the reader.
16. A method of making data relating to asphalt mix available at a paving site where said asphalt mix has been used to form a section of pavement, the method comprising the steps of:
(a) providing a tracking system that is configured to collect data related to the asphalt mix;
(b) depositing one or more tags into the asphalt mix, each tag provided with a first set of data related to the asphalt mix into which it is deposited;
(c) collecting and storing a second set of data related to the asphalt mix using the tracking system;
(d) associating the first set of data with the corresponding second set of data in the tracking system;
(e) depositing the asphalt mix at the paving site and forming the section of pavement;
(f) after the section of pavement is formed, retrieving the first set of data from one of the tags in response to wireless interrogation by a reader;
(g) wirelessly transmitting the first set of data sent from the one tag to the tracking system;
(h) wirelessly receiving second set of data that is sent from the tracking system in response to the tracking system receiving the first set of data,
wherein a first one or more tags that identify a portion of asphalt mix that is out-of-specification are deposited into the asphalt mix at a mixing site at irregular intervals and a second one or more tags are deposited into the asphalt mix at the paving site, the method further comprising removing the out-of-specification portion of the asphalt mix prior to depositing the asphalt mix at the paving site and forming the section of pavement.
