With the rapid economic development and continuous increase in consumption, a large amount of glass waste effect has been produced. The use of hydrated lime mixtures can improve the performance of asphalt concrete mix. It is expected that recycling of waste glass into asphalt mixture is possible. The aim of this study was to investigate the performance of asphalt concrete mixes in which the portions of fine aggregates were replaced by different percentages of aggregate content at 5%, 10%, 15% and 20%, respectively. Marshall is designed to investigate the effect of optimum bitumen content (O.A.C.) on various percentages of glass and water resistance. Next, by getting a cheap and economical mix that reduces O.A.C, increases the consistency and durability of the mix, as well as increases the slip resistance of the pavement, which will reduce accidents and save a lot of money. Through crushing and screening, the waste glass material can be used as fine aggregates in asphalt concrete, called glass slurry. Satisfactory performance of the upper asphalt pavement layer can be achieved by adding 10% glass waste to the mixture. The high volume of glass waste from industry has always been a significant issue nationally and globally. Glass recycling saves energy and reduces environmental waste. About 10 million tons of glass waste is generated in the world every year. Currently, the commercial use of waste glass in asphalt paving applications is limited to communities such as New York City, United States, where the amount of waste glass produced and collected provides a substantial incentive for recycling in pavement applications. Most early glass applications were limited to test pavements or special applications. In the late 1960s and early 1970s, a number of studies and field demonstrations were conducted in the United States to investigate the potential of using waste glass as a composite replacement material in hot mix asphalt. During this time, test flooring strips were installed at approximately 33 locations in the United States and Canada. From the mid-1970s to the mid-1980s, the city of Baltimore used glass in its street sidewalk plans. At least 17 streets are glazed to produce the "shiny" effect, which results from the reflection of sunlight or streetlights from the glass pavement. To design and operate a glass processing plant to process more than 12,600 metric tons (14,000 tons) of mixed waste glass for use as a total replacement in paving applications, during research in the mid-1980s. Activities were launched on Long Island. Recently, several paving projects using waste glass have been started around the world. However, the most revolutionary project to date has been undertaken by the New York City Department of Transportation, where approximately 225,000 metric tons of glass were used in resupply applications from 1990 to 1995. Early researchers identified both flat and elongated particles that can cause loose pavement, peeling, poor skid resistance, unusually high tire wear and excessive glare as potential problems. Since glass does not absorb any asphalt cement binder and since glass is also "hydrophilic", moisture damage (stripping) has been identified as a particular concern, especially when with high percentages and large gradations of surface layer mixing times. are presented. Many early researchers suggested adding lime as an anti-stripping agent to reduce potential stripping problems. Early glass stop projects used high percentages of glass (over 25% by weight of the mixture) and thicker glass gradations (greater than 12.7 mm (1/2 in)). Current data suggest that most of the peeling and settling problems reported in early road test demonstrations in the 1960s and 1970s may be due to the use of high glass percentages and large particle glass. The high angularity of the culvert can improve the stability of the asphalt mix compared to round sand, use an appropriately sized culvert. The consistency is reported to be comparable and, in many respects, better than conventional blends. Other beneficial properties include low absorption, low specific gravity, and low thermal conductivity, which are reported to provide enhanced thermal retention when mixed with glass. A proper mix design with the right material will ensure better performance of the existing roads. Some failures are expected to be due to poor design of the asphalt mix and/or materials used. The presence of different properties of local materials necessitates the use of various hybrid designs. One of the main issues in mix design is the type and quantity of filler used, which are known to greatly affect mix design, especially the optimum asphalt material. The amount of filler used in the plant mix will be a factor that affects the properties of the mixture produced. However, the exact quantity of this filler could not be determined due to loss of fine in the form of dust from the factory. When fillers are added to bitumen, it can significantly alter the stability of bitumen. This change can be clearly checked by increasing the viscosity, penetration and softening point of the bituminous filler mixture. Various studies have been conducted to investigate the properties of mineral fillers, notably those passing through a 0.075 mm sieve, and to evaluate their effect on asphalt paving mix properties, including stability, void filling, displacement. Resist contains water. Sensitivity, martial stability and mixing power. Shafabakhsh and Sajed (2014) reported that glass-asphalt concrete has improved dynamic properties, fatigue life, stiffness modulus and creep compliance compared to ordinary asphalt concrete. Arabani (2011) found that the behavior of hot mix asphalt (HMA) was improved at different temperature conditions (depending on changes in mix content and aggregate elevation) compared to HMA mixtures. Al-Kaisi (1981) studied the effect of filler-asphalt ratio on the properties of filler-cement and asphalt paving mixtures using five fillers. He notes that the range of filler-to-asphalt ratio required to produce the desired paving mix properties is affected by the type of filler used and should be set accordingly. In addition, he showed several locally available materials that can be used to replace Portland cement as a filler in asphalt paving mix.
