This product is made of a base mat or organic material (cellulose fibers) or inorganic material (glass fibers). Asphalt shingles are sometimes referred to as composite shingles. Its base is an organic felt or fiberglass base. Organic felt mats are made from cellulose fibers obtained from recycled paper or wood waste.
These fibers are reduced to a water-based pulp, formed into sheets, dried, cut into strips and rolled into rolls. Thinner and lighter shingles with greater fire resistance are made on a fiberglass base. In a typical process, the fiberglass membrane is manufactured by cutting thin glass filaments and mixing them with water to form a pulp, which forms into a sheet. The water is then sucked out of the pulp and a binder is applied to the mat.
After curing, the mat is cut into slices at appropriate widths and rolled up. A typical road section is constructed in several layers. The pavement is the surface layer and is made of concrete or asphalt. The base supports the pavement and is made of an aggregate base layer (AB) and sometimes of an aggregate subbase layer (ASB).
The subbase layer allows more sand, silt and clay. This layer has less resistance, but is used because it is cheaper when the road is level. Asphalt shingles are not made of asphalt all the way. Rather, they consist of a fiberglass base or felt paper, coated with an impermeable layer of asphalt and covered with ceramic granules.
Since its development in the 1980s, fiberglass base has been the most popular product. It is lighter and less expensive, but still provides considerable strength to the roof, as well as additional fire protection. You might be surprised to learn that asphalt shingles aren't made entirely of asphalt. The composition may vary, but asphalt shingles generally consist of mineral fiber and cementous fillers.
Studies have revealed that asphalt represents only 5 percent to 35 percent of the tile. This material is also called ACM, or “asphalt containing material”. Limestone rock, which normally reaches plants by truck or railway car, is processed by crushing mills into fine limestone powder. This powder is then mixed with the asphalt to make a product called a filler coating.
On the production line, kilometers and kilometers of rolled fiberglass mat that serves as the “backbone” of the tiles are deployed and inserted into a coating machine, where the filled coating, superheated to more than 400 degrees Fahrenheit, is applied to the top and bottom of the mat to create a base sheet. Fine fiberglass mats made of glass fibers of a specific length and diameter are joined together with the help of stable resins and binders. They are used to reinforce asphalt roofing shingles. This fiberglass adds weather protection, greater fire resistance and a longer lifespan to the roofing material.
Asphalt shingles remain the dominant residential roofing option in North America, and can also be found on roofs in many countries around the world. A variety of factors can affect the lifespan of shingles, such as the climate, the slope of the roof, the quality of the installation and, of course, the quality of the shingle. Since the asphalt coating of the roof tile is itself a sticky material, the bottom of the product must be covered with something to prevent the shingles from sticking to the processing rollers during manufacturing and sticking together in the package. The latest component of asphalt roofing shingles used to cause a bit of confusion in the amateur roofing community.
The asphalt on the roof must “oxidize” by blowing air through the hot asphalt, which increases its viscosity. Every day, thousands of tons of raw and manufactured materials are delivered to the cargo yards and reception docks of top-tier roofing plants in the United States. They are selected, processed and designed to work together to create a roofing material that, weight for weight, is among the best value for money options available. This site is about the recycling of asphalt roofing shingles or “composition shingles”, including quantities, composition, processing, products and products made from recycled asphalt roofing shingles.
Asphalt roofing shingles are reinforced with a thin fiberglass mat, made of glass fibers of specific length and diameter joined together with the help of stable resins and binders. Currently, SSPs for the base and subbase allow for “reclaimed asphalt concrete”, “Portland cement concrete”, “lean concrete base”, “cement treated base” or “glass”, but not roof shingles. These mineral granules are processed into a variety of colors by ceramic firing to help reflect the sun's rays and, at the same time, add beauty and style to the ceiling. These materials will be transformed into high-quality, durable roofing shingles and specialty products that have earned the respect of countless industry professionals and homeowners.
Roll roofs, which consist of long strips of asphalt coated felt with a finishing layer of finely crushed stone, have been manufactured in the United States since 1893. Caltrans pre-tests. As documented in a Caltrans memorandum dated July 24, 1996, Caltrans tested “crushed asphalt roofing shingles” in the spring of 1996 as 10 percent of AB for durability, and the results were favorable. In addition, special “reflective” granules can be used to make shingles that reflect a greater percentage of the sun's thermal energy.
