There is a strong demand for asphalt mixtures using renewable bioasphalt binders as paving materials. Due to the smaller amount of oil and the price is usually more expensive. Asphalt as a demand for pavement, whether maintenance, improvement, or development of road accessibility, is constantly increasing with the growth of construction. Asphalt as a paving material is in great demand. As oil prices have risen in this decade, concerns have also arisen. Therefore, other alternative materials are needed as an alternative to conventional asphalt, there are asphalts derived from biomass or commonly referred to as bioasphalt. In the construction world, most flexible road structures use synthetic bitumen derived from crude oil, also known as conventional bitumen. Therefore, in the search for more sustainable construction, people around the world are very interested in finding bioasphalt. There are several reasons for using bioasphalt, such as asphalt mixes from plants and trees, as an alternative to petroleum-based mixes. One bioasphalt that can be used as an alternative to conventional asphalt is tar (damar). The percentage of natural resin used in conventional 60/70 bitumen handles is 0%, 2.5%, 5%, 7.5% and 10% modified. On the other hand, the optimal content of bitumen is close to that of modified natural resin. The term "hot mix" is commonly used to refer to the many different types of asphalt and aggregate mixes produced in asphalt plants. The most common hot mix asphalt is divided into different components, which are then divided into three different types of aggregate based mixes: (i) tight granular mixes, (ii) open granulated mixes, and (iii) gradation of aggregates used. 
Design of asphalt concrete mixture
The design of asphalt concrete, the desired properties of its constituent materials and the ratio of their mixtures are of great importance and must be carried out taking into account the entire life cycle and final design of these materials. Meeting the long-term performance requirements of embedded materials is the overall goal of a Life Cycle Assessment (LCA). Thus, when evaluating, it is necessary to evaluate the characteristics of the material, taking into account the entire period of its useful life from the moment it is put into the building until it is disposed of or recycled. The purpose of the evaluation is to verify compliance with the standards set for these materials and should guarantee usability and performance throughout their life. As the main part of the mixture, the gradation of the aggregate plays an important role in the structure and characteristics of the mixture. The test is carried out on the basis of AC classification and SMA classification. According to the rating range and performance indicators, a mixture is given and a classification proposal for anti-slip coating is studied. Since the graded fiber stabilizer was not used in this experiment, compared with the conventional SMA blend, the fine aggregate content above 4.75 mm decreased, the fine aggregate content increased, and the gradation was fine, but it did not matter for the formation of an interconnected skeletal structure. Due to the finer gradation, the aggregate removal rate will be reduced and the amount of asphalt used will be reduced accordingly. At present, there are many roads with large longitudinal slopes on mountain roads, but we hope to improve the anti-skid performance on long and steep slopes. There are many factors that determine the anti-skid performance of a pavement, among which the composition of the asphalt concrete mix is one of the key factors. Combining the advantages of AC-13 and SMA asphalt concrete, this paper offers an economical and practical asphalt mix ratio. When developing a target mix ratio, since the screening of various characteristics of aggregates is too cumbersome and laborious, each set of production mix ratios must be developed in accordance with the selection results. However, no matter how the ratios of 5 fillers changed, it was not possible to achieve the target ratio of the mixture. The description of the aggregate grade in the test is not very reasonable. Therefore, in the actual construction, the aggregate proportion must be adjusted by itself to improve the grade level of the ore. By formulating 5 aggregate proportions for construction, work efficiency has been greatly improved. 
Asphalt Concrete Mixtures
Asphalt concrete mixtures can be classified in different ways. Perhaps the most common type of classification is based on whether the mixture must be heated before being transported, laid and compacted. Asphalt concrete must be thoroughly heated during mixing, transport, pouring and compaction. Asphalt binders used in asphalt mixes can become hard and brittle at room temperature, so once cooled, this type of asphalt becomes hard enough to withstand heavy traffic. On the other hand, cold asphalt concrete is usually processed, placed and compacted without heating. This material can be cold processed as it uses liquid bitumen in the form of an emulsion and diluents that are liquid at room temperature. It should be noted that the properties of asphalt concrete in an asphalt concrete mixture will differ significantly from the properties of the mixture before production. Asphalt cement is heated at different times and over a wide range of temperatures during its mixing, curing and service life. During these processes, the structure and composition of bitumen molecules undergo significant changes, mainly due to the volatilization of light hydrocarbon components and reaction with ambient oxygen. These changes in turn cause the asphalt binder to become harder or less ductile, a phenomenon known as age hardening or aging. In addition, asphalt concrete is present in asphalt concrete in the form of a thin film. Their behavior and properties in this form are completely different from those of "bulk" materials, and the oxidation or aging reaction proceeds faster. 
Hot-mix asphalt concrete (HMA) This is achieved by heating the bituminous binder to reduce its viscosity and drying the aggregate to remove moisture from it before mixing. Mixing is typically carried out at about 300°F (about 150°C) virgin asphalt and 330°F (166°C) polymer modified asphalt and 200°F (95°C) asphalt binder. Laying and compaction should be done when the asphalt is hot enough. In many countries paving is limited to the summer months because in winter the compacted base layer cools the asphalt too much before it can be compacted to the desired density. HMA is the form of asphalt most commonly used on high traffic sidewalks such as major highways, runways and airports. It is also used as an environmental liner in landfills, reservoirs and fish farms. Warm Mix Asphalt (WMA) It is made by adding zeolite, paraffin, bituminous emulsion or sometimes even water to the bituminous binder before mixing. This can significantly reduce mixing and styling temperatures, as well as reduce fossil fuel consumption, resulting in less carbon dioxide, aerosols and steam. Not only are working conditions improved, but lower paving temperatures also result in faster surface utilization, which is important on construction sites with critical schedules. The use of these additives in hot mix asphalt facilitates compaction and allows paving in cold weather or transport over long distances. The use of warm mixes is rapidly expanding. Cold-mix asphalt concrete This is done by emulsifying the bitumen in water with an emulsifier before mixing it with the aggregate. In the emulsified state, the viscosity of the bitumen is low, the mixture is easy to process and thick. Once enough moisture has evaporated, the emulsion breaks down and ideally the cold mix will have the characteristics of an HMA pavement. Cold mix is often used as a repair and maintenance material for lighter traffic roads. 
Renewable Bioasphalt Binder
Bioasphalt binders for asphalt pavements are made from environmentally friendly materials which is renewable and can replace traditional asphalt pavement layers. In this study, a bio-asphalt binder made from Damar resin mixed with latex polymer, waste boiled oil and fly ash as a filter. Bioasphalt binders are Avello's proprietary pyrolysis petroleum distillate blends suitable for use as an additive or replacement for bituminous materials. Bioasphalt binders are produced using Avello's fast pyrolysis technology. The US economy is heavily dependent on an aging transportation infrastructure: 90 percent of US roads and highways are paved. Refinery modifications have been made in recent years to maximize liquid fuel production, reduce bitumen supplies and increase prices. The limited supply of bitumen, coupled with potential carbon capture and storage to reduce carbon emissions, provides an economic opportunity to produce renewable and sustainable bitumen building materials. Petroleum bitumen is a residue of traditional crude oil refining processes and is mainly used in road construction and roofing. Many refineries in the US have switched to heavier feedstocks and installed oil cokers that do not produce bitumen. These changes in processing have meant that there is less bitumen on the market. Several states have reported shortages of liquid asphalt or petroleum-derived polymers that improve asphalt pavement performance. From 2004 to 2008, the price of bitumen rose sharply during a period of rising commodity prices as crude oil prices rose. The advantages of bioasphalt binders include: Renewable: Bioasphalt binders are produced domestically from non-food sources such as agricultural and wood waste. The use of bioasphalt binders obtained from biomass reduces our country's need for imported oil. Instant: Extensive research at Iowa State University has shown that bio-oil fractions can directly replace petroleum-based liquid asphalt as additives, modifiers, or fillers in existing road and roof surfaces. Reduce your carbon footprint: Bioasphalt binders can lower hot mix production temperatures, reduce paving costs by 20%, and reduce greenhouse gas emissions by up to 30% because less energy is required. Bioasphalt binders also have an antioxidant effect, which can increase the life of the pavement. The addition of bioasphalt binders can expand the range of asphalt. Cost competitiveness: Our economic analysis shows that, without subsidies, the price of bioasphalt binders could be at or below today's bitumen prices. 
Properties of asphalt concrete mixture
Performance and design requirements are an important part of any asphalt mix. The agency or body responsible for the construction of the pavement usually develops the mix design methods and design requirements. Once they are determined, the contractor/manufacturer and their technicians are responsible for developing the mixture within the requirements of the specification. Asphalt mixes must be designed, manufactured and placed in such a way as to provide the following desired mix properties: stabilize Durability flexibility Anti-fatigue slip resistance impenetrability machinability Current testing of asphalt concrete includes physical and mechanical properties. Physical properties include voids, voids filled with bitumen/asphalt, voids in mineral aggregates, aging. Mechanical testing can be done with Marshall stability, Hveem stability, cohesion, modulus of elasticity, modulus of elasticity (indirect tensile reload), indirect method of modulus of stiffness, dynamic compound modulus, bending test, indirect tensile, creep and constant set, machine for Rotational Testing (GTM), Wheel Lab Testing, Moisture Sensitivity Testing. 
- Stability is the ability of an asphalt mix to withstand traffic loads without permanent deformations such as waves and grooves.
- Fatigue resistance refers to the elasticity of the asphalt mix to withstand repeated loads without fatigue in the form of grooves and cracks.
- Durability refers to the ability of an asphalt mix to maintain its properties when the road is damaged by weather, water and traffic loads.
- Water resistance - the resistance of a mixture to water causing loss of adhesion between aggregate and asphalt in the surface layer.
- Slip resistance is the combination of the compound as a surface layer, so that in rainy or humid weather, the car can move without slipping. Workability is how easily a mixture can be coated and compacted to achieve the desired density.
