The weight of an asphalt pavement depends upon the aggregate type, the bitumen, and the air void content. An average example in the United States is about 112 pounds per square yard, per inch of pavement thickness. [21]
Otta seal is formed by adding graded aggregate to a soft bituminous binding agent. The agent is usually emulsified asphalt.Bituminous binder application rates are between 1.9 liter/m 2 (0.42 US gallon/yard 2) and 2.4 liter/m 2 (0.53 US gallon/yard 2) – the value is dependent on aggregate gradation and type.
Bituminous geomembrane (BGM) is a type of geomembrane consisting of a reinforcing geotextile to provide mechanical strength and elastomeric bitumen (often called asphalt in U.S.) to provide impermeability. Other components such as sand, a glass fleece, and/or a polyester film can be incorporated into the layers of a BGM. [1]
The weight designations originated with organic base felt weighing 15 or 30 pounds per 100 sq. ft. (6.8 kg or 14 kg per 9.3 m 2). However, modern base felts are made of lighter-weight fibre, so the weight designations, though common colloquially, are no longer literally accurate. [ 2 ]
Several variations of bitumen roofing felt are available. Single coverage thicknesses range from 55 to 90 pounds per square (100 sq. ft.) for single-coverage; Double coverage range from 110 to 140 pounds per square. [4] Fibre content: mixed rag fibre - lowest cost, shortest life; all plastic fibres; fibreglass - longest lived; Bitumen:
Asphaltite (also known as uintahite, asphaltum, gilsonite or oil sands [1]) is a naturally occurring soluble solid hydrocarbon, a form of asphalt [2] (or bitumen) with a relatively high melting temperature. Its large-scale production occurs in the Uintah Basin of Utah and Colorado, United States.
A more durable road surface (modern mixed asphalt pavement), sometimes referred to in the U.S. as blacktop, was introduced in the 1920s. Instead of laying the stone and sand aggregates on the road and then spraying the top surface with binding material, in the asphalt paving method the aggregates are thoroughly mixed with the binding material ...
A Bitubale is baled asphalt, in cold form, wrapped in white plastic or in asphalt-based film. Invented by Singapore-based Eastern Petroleum Group, [1] Bitubale is a green technology innovation for the global bitumen transport supply chain. Bitubales are produced in specially designed plants for cooling, dispensing, encapsulation, and packing of ...
