Granulation accounts for a large part of the composition and mass of a mixture which make it obvious that it is an important part of the asphalt mixture and plays an important role in characteristics performance. In this study, three gradations within the scope of Gradation Specification No. 4 for Iranian Made Asphalt Mixtures with Marshall Test, Moisture Sensitivity and Dynamic Creep are used to compare the performance characteristics of different mixtures. Wrinkles have been measured using psycho-numerical parameters, and a combination of visual and mechanical testing has been used to assess moisture sensitivity mechanisms. 
In conclusion, the lower bound granularity of the established rules has the best performance results compared to the other granularities examined in this study. Furthermore, in this study, a method to quantify boiling water results (in ASTM standards) using image processing in MATLAB software is presented. Mineral fillers are an integral part of the asphalt mix and affect its performance. This study investigated the effect of using four local industrial waste/by-product materials (marble, granite, steel slag and slaked lime powder) as mineral fillers on asphalt mix properties. Detailed properties of these materials and properties of asphalt binder and asphalt mixture are presented. In Egypt, limestone powder is a typical mineral filler in asphalt mix compositions. A control asphalt mixture containing limestone mineral filler was designed using the Marshall method. With the exception of replacing the limestone filler with other types of industrial waste/by-product material, the other four asphalt mixtures were prepared using the same composition and volume, while maintaining the same percentage of the mineral filler as in the control mixture. went. The marshall stability and moisture-induced damage of the studied asphalt mixture were determined and the results were compared to the control asphalt mixture. In addition, the performance characteristics of the studied mixtures were evaluated by performing cyclic performance tests including dynamic modulus (E*) and flow number (FN). Test results show that asphalt mixture with marble as filler has the highest stability; While slaked lime filler significantly improves the moisture damage resistance of the asphalt mix, E* and FN. 
Unsurprisingly, steel slag filler did not improve the performance of the asphalt mix. Asphalt paving mix contains mineral aggregates, bitumen and optional additives to bind the aggregates. Conventional dense grade asphalt, also known as asphalt concrete or hot mix asphalt (HMA), consists of about 5 percent asphalt and about 95 percent aggregate. Special Advanced Surface Asphalt Mix (Special Advanced Surface Asphalt Mix) is a new line of asphalt mix for paving applications. Premium surface asphalt mixes in this category include porous asphalt mixes and masticated asphalt mixes (SMA). Porous asphalt mixes (also known as "silent asphalt" or "draining asphalt") contain smaller and smaller aggregate particles, but no medium-sized particles. SMA, also known as stone mastic, split mastic, grit mastic or stone filled asphalt, was originally developed to provide a composite material that maximizes the wear of studded tires. This resistance is achieved through the use of a high ratio of bulk aggregate particles, resulting in interlocking and direct rock-to-rock contact. SMA has also been shown to provide high resistance to plastic deformation and good low temperature performance under heavy traffic loads and high tire pressures. In addition, SMA has a rough surface texture that provides good abrasive properties once the bitumen surface film is taken away. Other important features that make SMAs more desirable than traditional high-density HMAs include increased durability, improved aging performance, reduced traffic noise, and reduced or prevented rainwater seepage on paved surfaces. Advanced asphalt mixes, especially silent asphalt and SMA, experience asphalt mix damages after production and during transportation and storage. This phenomenon makes it impossible to use these compounds without immobilization. The common stabilization method is to add filaments, usually cellulose or mineral fibers, to the mixture. Polymer fibers can also be used for this purpose. Fibers are typically present in asphalt mixtures at levels between 0.3% and 0.5% based on 100% dry total weight. 
While fiber stabilization provided a reasonable level of bitumen loss (below 0.1%), it also resulted in decreased mixing performance. The mixing time required for the fiber-stabilized mixture is approximately 2 min, compared to the mixing time of 1 min required for conventional HMA. Additionally, due to the increased compaction resistance of filament-filled asphalt mixtures, higher mixing temperatures are required relative to conventional asphalt mixtures. Finally, the bitumen content should be increased from about 5% in conventional HMA to about 7-10% in order to provide proper fiber coating as well as aggregate particles. All these disadvantages increase the cost of production of bitumen. Prolonged mixing slows down production, while higher required temperatures increase energy consumption. Asphalt is the most expensive component in the asphalt mix, and increasing the proportion of asphalt in the SMA can significantly increase the cost. In addition, the production parameters required to utilize the fiber also impose an environmental burden. Maintaining high temperatures for long periods of time can lead to increased energy consumption and greenhouse gas emissions. Additional asphalt must be obtained, which is an energy-intensive process. Cellulose fiber requires the consumption of the trees themselves and their processing. The first embodiment of the present invention is a composition (interstitial graded asphalt) that can be used as an additive to asphalt mixtures such as SMA, porous asphalt and gap graded asphalt. 
In one embodiment, the composition includes the mineral kaolinite, found exclusively in sediments in the Dead Sea region of Israel, and a catalyst. In a preferred embodiment, the catalyst is a quaternary ammonium compound. The compositions of the present invention are preferably provided in powder form. Powder particle size is preferably less than 40 µm. When amorphous silica is included in the composition, the particle size of silica is approximately 1–10 µm. The composition provides thixotropic and pseudoplastic properties to the asphalt mixture, reducing mixing time and effort during mixing, laying and compaction of the asphalt mixture compared to the temperature of the fiber-modified asphalt mixture.
