The fine aggregate plays a vital role in the performances of asphalt mixture. In this paper, four kinds of fine aggregates with different lithology, apparent density and water absorption rate were discussed. Asphalt mixture according to AC-13 is prepared by these four kinds of fine aggregates and the volumetric properties, water stability performance and high …

· Asphalt fine aggregate matrix (FAM) is a predominant component directly related to field performances of hot asphalt mix (HMA), it is necessary to investigate material properties of FAM. Prior to preparing FAM specimens, the asphalt content was calculated by keeping the filler–bitumen (FB) ratio the same as in the corresponding HMA. A non …
· Asphalt fine aggregate matrix (FAM) consists of a binder, fine aggregate, filler, and air voids. Studies on FAM, which is one scale smaller than asphalt concrete (AC), have been gaining attention among researchers because of its considerable similarities with AC and increased testing efficiency it provides. FAM tests are mostly performed to evaluate …
· At the surface levels, however, they are smaller and more angular. To extend pavement life, fine aggregate particles may be added to the mix. The climate in which you will use the asphalt pavement can affect the ingredients. Asphalt made for hotter climates is more difficult to withstand, while asphalt made for colder climates is easier.

· Asphalt mastic is a blend of asphalt binder and mineral filler smaller than 0.075 mm while asphalt mortar consists of asphalt binder, mineral filler and fine aggregate smaller than 2.36 mm.
This study investigated the common aging protocols for binders and asphalt mixtures on fine aggregate matrix (FAM). Currently, no unified aging protocols are specified for laboratory-prepared FAM. The majority of FAM-related aging research used asphalt binders and mixture aging specifications. However, the practicality of employing these ...
· The graded mineral aggregate composed of coarse aggregate, fine aggregate, and mineral powder is the main component of hot asphalt mixture (HMA), and it occupies a mass ratio of more than 95% in HMA.
· In this study, the usability of expanded glass (EG) in hot-mix asphalt (HMA) as the fine material is investigated. Firstly, standard tests on the EG have been done to determine the basic properties. Next, optimum binder content and aggregate gradation are determined in accordance with Superpave volumetric mix design.
· To ensure the integrity of asphalt mixture, fine aggregate is added to the framework of coarse aggregate, which have crucial effect on the shear resistance of …
· Fine aggregate in cold mixture asphalt was replaced with 50% of crumb rubber. Three different sizes of crumb rubber, 20 mesh (0.841 mm), 40 mesh (0.42 mm) and 60 mesh (0.25 mm), were applied in a series of laboratory experiments. Tests were done using Marshall Test equipment to obtain the mechanical performance of cold mixture asphalt.

· Use of recycled asphalt in asphalt mixtures and their characteristics. RAP (recovered asphalt pavement) is the asphalt achieved by breaking, crushing or grinding existing old asphalt and has about 95% good quality aggregates, which are wrapped in bitumen [ 6 ]. For that reason, the use of recycled asphalt (RAP) has been a very …
· While the use of steel slag fine aggregate in asphalt mixture is rarely reported due to some poor performances and high cost factors. On the one hand, the angularity …
The value of a specific fine aggregate fraction is reported as milligrams of methylene blue per gram of specific fine aggregate fraction such as: MBV = 5.3 mg/g, 0/#200. The MBV expresses the quantity of required to cover the total surface of the clay fraction of the sample with a mono-molecular layer of the .

· Since a considerable amount of steel slag is produced in the southwestern part of Pennsylvania around Pittsburgh, where natural fine aggregate sources are limited, an evaluation was undertaken to determine the feasibility of using "cured" steel slag fine aggregate in hot-mix asphalt (HMA) mixtures.
· This study addresses the relationship between fine aggregate shape properties and the performance of hot-mix asphalt. Aggregate shape was expressed as three independent properties: form, angularity, and texture. Image analysis procedures and indices were developed to capture these properties. The indices were measured for 22 …

The maximum size used is 80 mm and the range of 80 mm to 4.75 mn is known as coarse aggregate and 4.75 to 150 µm is called fine aggregate. Size 4.75 mm is common for both …
Qualities of fine aggregates: Fine aggregate should be clean i.e. it should be free from lumps, organic material, etc. It should be strong and durable. It should not react with cement after mixing. Also, it should have a tough floor. It should not absorb greater than 5% of water. These types of aggregates should not be soft and porous.
The fine aggregate specific gravity test (Figure 1) ... However, aggregate and asphalt binder volumes are diffucult to measure directly, therefore a material's weight is typically measured and then converted to a volume …
· That portion of an aggregate passing the 4.75 mm sieve and predominantly retained on the 75 µm sieve is called "fine aggregate" or "sand," and larger aggregate is called "coarse aggregate". Coarse …
