Otta seal is a type of bituminous surface treatment that was developed by the Norwegian Road Research Laboratory (NRRL). Its name is based on the location in which it was created, the Otta Valley. Otta seal was developed to be used as a temporary surfacing on new roads; however, after seeing its strength, it has been used as permanent roads as ...
Dust abatement refers to the process of inhibiting the creation of excess soil dust, a pollutant that contributes to excess levels of particulate matter. Frequently employed by local governments of arid climates such as those in the Southwest United States , dust abatement procedures may also be required in private construction as a condition ...
Magnet is a chloride chemical that uses the moisture in the atmosphere to prevent dust from moving on the road; however this is typically less effective. DustWorx is a concentrated polymer that works to prevent dust particles from forming at the surface. These chemicals are all environmentally safe. [17]
Chipseal (also chip seal or chip and seal) is a pavement surface treatment that combines one or more layers of asphalt with one or more layers of fine aggregate. In the United States, chipseals are typically used on rural roads carrying lower traffic volumes, and the process is often referred to as asphaltic surface treatment.
New macadam road construction at McRoberts, Kentucky: pouring tar. 1926. With the advent of motor vehicles, dust became a serious problem on macadam roads. The area of low air pressure created under fast-moving vehicles sucked dust from the road surface, creating dust clouds and a gradual unraveling of the road material. [18]
Dust-laden gas or air enters the baghouse through hoppers and is directed into the baghouse compartment. The gas is drawn through the bags, either on the inside or the outside depending on cleaning method, and a layer of dust accumulates on the filter media surface until air can no longer move through it.
Dirt roads almost always form a washboard-like surface with ridges. The reason for this is that dirt roads have tiny irregularities; a wheel hitting a bump pushes it forward, making it bigger, while a wheel pushing over a bump pushes dirt into the next bump. However, the surface can remain flat for velocities less than 5 mph (8 km/h). [2]
Asphalt road being milled in preparation for repaving. Pavement milling (cold planing, asphalt milling, or profiling) is the process of removing at least part of the surface of a paved area such as a road, bridge, or parking lot. Milling removes anywhere from just enough thickness to level and smooth the surface to a full depth removal.
