Well-graded aggregate is also known as uniformly-graded aggregate.Īir Voids: Empty spaces in a compacted mix surrounded by asphalt-coated particles, expressed as a percentage by volume of the total compacted mix.Īlligator Cracks: Interconnected cracks forming a series of small blocks resembling an alligator’s skin or chicken-wire, and caused by excessive deflection of the surface over unstable subgrade or lower courses of the pavement.Īsphalt (Asphalt Binder or Asphalt Cement): A dark brown to black cementitious material in which the predominating constituents are bitumens which occur in nature or are obtained in petroleum processing. Well-Graded Aggregate: A gradation with relatively uniform proportions from the maximum size down to filler with the object of obtaining an asphalt mix with a controlled void content and high stability.Open-Graded Aggregate: A gradation containing little or no mineral filler and in which the void space in the compacted aggregate are relatively large, usually 10% or more.Stone Matrix Asphalt (SMA) is a common example of a gap-graded asphalt pavement. Gap-Graded Aggregate: A gradation consisting of larger and finer particles but little or no particles in the middle of the gradation band creating a “gap”.Fine-Graded Aggregate: A gradation having a continuous grading in sizes of particles from coarse through fine with more material smaller than the primary control sieve.
Dense-Graded Aggregate: A gradation that has a particle size distribution such that when it is compacted, the resulting voids between the aggregate particles, expressed as a percentage of the total space occupied by the material, are relatively small.Coarse-Graded Aggregate: A gradation having a continuous grading in sizes of particles from coarse through fine with more material larger than the primary control sieve.The most common mineral fillers include pulverized limestone, other stone dust, hydrated lime, Portland cement, fly ash, and certain natural deposits of finely divided mineral matter.Īggregate Gradation: The particle size distribution from the largest through finest materials. 30) sieve and at least 70 percent of which will pass a 0. Mineral Filler: A finely divided mineral product with a maximum of 3 percent retained on the 0.Fine Aggregate: Aggregate particles passing the 2.
ZIP file with PBR texture includes follow PBR MAPS Here are two categories with our PBR textures: All PBR are High Resolution at 4K resolution. PBR created from realistic photo textures or PBR created in Substance Designer. You can find two kinds of PBR on our website. It can be referred to as Physically Based Rendering ( PBR) or Physically Based Shading (PBS). Physically Based Rendering ( PBR) is a method of shading and rendering that provides a more accurate representation of how light interacts with surfaces.
