Article History : Article entry : 2021-09-30 Article revised : 2021-12-09 Article received : 2021-12-16 Aus-Layered Asphalt Concrete (AC-WC) is the topmost layer of the pavement structure that is directly related to the vehicle wheels. WC) in this study selected tire ore waste as an added material to the job mix. In this study, the variation of the mixture added with tire ore starting from 0%, 3%, 6% and 8% addition of tire ore waste for the highest variation value is 3%, stability value is 494.99 kg, Voids Filled With Asphalt’s value is 68,40%, value of Voids in Mix is 3.65%, flow value is 3,21 %, value of Marshall Quotient is 154,61 kg/mm, Density’s value is 2,29 gr/cc. Finally, it was concluded that the addition of waste tire ore is not in accordance with SNI 06-2489-1991 because the higher percentage value in the mixture will decrease the value of Marshall Stability.


Introduction
Roads are the most dominant transportation infrastructure used, judging from the high intensity of road users [1] [2], the maintenance and construction of roads must also have good quality and there must be innovation updates from time to time on the infrastructure of road construction [2] [3].
Aus Layer Asphalt Concrete (AC-WC) is the topmost layer of the pavement structure that is directly related to the vehicle wheels [4] [5], has a smoother texture than Intermediate Asphalt Concrete (AC-BC), in this study tire ore was chosen as an added material. Asphalt Lapis Aus (AC-WC) due to the lack of utilization of tire ore and the nature of the ore itself is elastic which is suitable to be mixed with Asphalt Lapis Aus (AC-WC) [5] [6].

Literature Review
in previous research that has been carried out with the title "The Effect of Adding Waste Tire Powder as a Substitute for Fine Aggregate on the Stability of the AC-WC Layer. -WC)" containing granules/waste of tire powder and comparing with asphalt mixture without waste of tire powder [7].
The mixing method used in this study is the middle limit of the AC-WC mixture gradation in the requirements of Highways. 30 has an optimum asphalt content of 5.75% and a mixture with 100% waste tire powder as a substitute for aggregate in fraction No. 30 has an optimum asphalt content of 6.05%. The results of the Marshall Immersion test show the residual strength index of the AC-WC mixture with 50% waste tire powder as a partial substitute for aggregate in the No. fraction. 30, has the largest value of 95.49%. The optimum mixture was obtained in a mixture containing waste tire powder as a substitute for fraction No. 30 as much as 56% by 95.645%

Research method
In this research will do some stages in general. Starting with the preparation stage, the data collection stage, materials and equipment to be used such as waste tire ore, coarse aggregate, fine aggregate, asphalt, as well as test objects, then proceed to the data analysis stage and the last stage is drawing conclusions [8][9][10].

Data Collection Techniques
In compiling this report, the researcher carried out several methods of collecting data, which included primary and secondary data collection at the time of the research [10]. Is the data obtained from the results of experiments / experiments in the laboratory. In this case, it includes data on aggregate inspection, asphalt inspection and inspection of test objects (briquettes) [11].

Interview
Interviews are data collection techniques that are carried out face-to-face and direct questions and answers to informants [12]. Like when before making a job mix formula. The researcher also asked directly to people who understood the process of making asphalt mixtures, especially to laboratory lecturers, and the head of the laboratory [13].

Documentation
During the implementation of the research, starting from taking water hyacinth in the river to alleviating test objects (briquettes) the research always documents it, with the aim that from the documentation that researchers can take, hopefully later it can be useful in preparing reports [13].

Observation
Observation is data collection where researchers go directly to the Lamongan Islamic University laboratory to conduct direct research on the utilization of used tire ore waste on the AC-WC asphalt mixture [14] [15]. From this, it is hoped that researchers will be able to find out how the effect of adding waste tire ore to the asphalt mixture and so that researchers can find out various kinds of work process situations (conditions) in the laboratory [16][8].

Secondary Data Collection
Secondary data is data obtained indirectly, for example from previous research references and references from literature books [17]. In this case the researcher collects data by visiting the library, study center, archive center, journal or reading many books related to his research [18] [19].

Data Analysis
After doing research on the addition of a mixture of waste tire ore to the hot asphalt mixture, researchers can compare the results of the Marshall Properties test using 4 types of test objects in which 4 test objects are given before being added and after being given additional waste tire ore [20] [21]. After testing and research, the results will be obtained, which is then carried out by making mathematical modeling with the help of MS Excel 2013 software to determine the relationship between the additional levels of waste tire ore, (i) asphalt quality; and, (ii) values of marshall properties [22]. The final result is a mathematical model of the relationship between the addition of waste tire ore: (i) asphalt

Marshall Test Test Process
Marshall test refers to SNI 06-2489-1991, with the final test results to determine the value of marshall stability, flow, marshall quotient, voids filled with bitumen, voids in mineral aggregates and voids in mineral aggregates [23]. air voids (voids in mix) where the hot asphalt mixture is added with waste tire ore [24].  The density value is the volume weight value to show the density of the asphalt concrete mixture. From the dendity graph, the highest density is 2.33 gr/cc. If the MQ value is too high, the mixture will tend to be too stiff and easy to crack.

Relationship between Tire Ore Waste and VIM
Conversely, if the MQ value is too low, the pavement becomes too flexible and tends to be less stable. From the MQ graph above, the highest value is 447.40 kg/mm.

Conclusion
From the results of tests conducted regarding the effect of mixing tire ore on hot asphalt, the following conclusions can be drawn:  2. So that future researchers will be more careful in conducting research, both during the calculation process, weighing, making test objects, and testing test objects.
