Gabions are manufactured with all components mechanically connected at the production facility to manufacture high-quality wire, as per ASTM A975-97 and ISO-03-0090-1999. All gabions are given in the form of collapse, either folded or rolled and bundled. Files are compressed and bonded together at the factory for easy shipping and handling. Lacing wire shipped in rolls. Fasteners are shipped in boxes. Preformed stiffeners shipped in bundles. Made from a thick galvanized mild steel wire, woven through supervision and meticulous process in accordance with the standard.
Aspal adalah bahan hidro karbon yang bersifat melekat (adhesive), berwarna hitam kecoklatan, tahan terhadap air, dan visoelastis. Aspal sering juga disebut bitumen merupakan bahan pengikat pada campuran beraspal yang dimanfaatkan sebagai lapis permukaan lapis perkerasan lentur. Aspal berasal dari alam atau dari pengolahan minyak bumi.
Aspal atau bitumen adalah suatu cairan kental yang merupakan senyawa hidrokarbon dengan sedikit mengandung sulfur, oksigen, dan klor. Aspal sebagai bahan pengikat dalam perkerasan lentur mempunyai sifat viskoelastis. Aspal tampak padat pada suhu ruang padahal adalah cairan yang sangaaat kental. Aspal merupakan bahan yang sangat kompleks, dan secara kimia belum dikarakterisasi dengan baik. Kandungan utama aspal adalah senyawa karbon jenuh, dan tak jenuh, alifatik, dan aromatic yang mempunyai atom karbon sampai 150 per molekul. Atom-atom selain hidrogen, dan karbon yang juga menyusun aspal adalah nitrogen, oksigen, belerang, dan beberapa atom lain. Secara kuantitatif, biasanya 80% massa aspal adalah karbon, 10% hydrogen, 6% belerang, dan sisanya oksigen, dan nitrogen, serta sejumlah renik besi, nikel, dan vanadium. Senyawa-senyawa ini sering dikelaskan atas aspalten (yang massa molekulnya kecil), dan malten (yang massa molekulnya besar). Biasanya aspal mengandung 5 sampai 25% aspalten. Sebagian besar senyawa di aspal adalah senyawa polar.
Sumber : Dari Wikipedia bahasa Indonesia, ensiklopedia bebas Shell Bitumen 60/70 is a penetration grade bitumen used in road and airport constructions and other similar applications. Paving Asphalt 60/70 S is a penetration graded asphalt product derived from specially selected crude oils via carefully controlled refining processes.
The quality of ExxonMobil products is assured for every delivery. They are produced and controlled according to the ExxonMobil Product Quality Management System, EN ISO 9000 or equivalent standard.
“Jey Oil Bitumen / Aspal Iran” The bitumen is provided during the process of oxidation of vacuum bottom in bitumen production units. Due to its medium air blowing and penetration, is used in mild areas.
Geosynthetics are the generally polymeric products used to solve civil engineering problems. This includes eight main product categories: geotextiles, geogrids, geonets, geomembranes, geosynthetic clay liners, geofoam, geocells and geocomposites.
The polymeric nature of the products makes them suitable for use in the ground where high levels of durability are required. Properly formulated, however, they can also be used in exposed applications. Geosynthetics are available in a wide range of forms and materials, each to suit a slightly different end use.
These products have a wide range of applications and are currently used in many civil, geotechnical, transportation, geoenvironmental, hydraulic, and private development applications including roads, airfelds, railroads, embankments, retaining structures, reservoirs, canals, dams, erosion control, sediment control, landfll liners, landfll covers, mining, aquaculture and agriculture.
Geogrids are either stretched in one or two directions for improved physical properties, made on weaving or knitting machinery by standard manufacturing methods, or by bonding rods or straps together.
There are many specific application areas, however, they function almost exclusively as reinforcement materials.
The latest development in stiff polymer geogrid manufacture is based on an isosceles triangular aperture, produced by a new manufacturing technique from a punched then stretched polymer sheet.
Uniaxial Geogrids are polymers formed into a very open, is manufactured from Polypropylene (PP) or High Density Polyethylene (HDPE).
It is produced through the process of extruding, punching, heating and stretching. With Performance High Tensile Strength, High elastic modulus and Low Creep Deformation.
Application:
Mainly used in the highway, railway, retaining wall, dam and steep slope
Benefits:

Product Applications – Paving Asphalt 60/70 S is recommended for road construction. If other applications are considered, then users should conduct appropriate testing before use.
Geobags are small soil containers that made of either woven or non-woven geotextile.
They are filled with sand and stitched manually to form a bag.
Geobags are used for the protection of hydraulic structures and riverbanks from severe erosion.
