Asphalt concrete (commonly called asphalt, blacktop, or pavement in North America, and tarmac, bitumen macadam, or rolled asphalt in the United Kingdom and the Republic of Ireland) is a composite material commonly used to surface roads, parking lots, airports, and the core of embankment dams. Asphalt mixtures have been used in pavement construction since the beginning of the twentieth century.
Asphalt milling is a recycling and re-paving procedure, aimed at removing the top layer of asphalt from a street, parking lot or driveway without disturbing the sub-base. Once the asphalt is milled up, it is taken to an asphalt plant where it's screened and sized again and then used to make new pavement.
"Use constituting disposal" is recycling that involves the direct placement of wastes or products containing wastes (e.g., asphalt with petroleum-refining wastes as an ingredient) on the land. "Burning for energy recovery" is recycling that involves burning a hazardous waste for its fuel value (either directly or when it is used to produce a fuel).
The Alliance to End Plastic Waste (AEPW) was founded in 2019 by over 80 plastic manufacturers from around the world.

WMGR082 (pdf) Processing and beneficial use of steel and iron slag and refractory bricks mined from an existing slag pile for use as a construction material.
The major approach to solve this issue is to recycle waste tyre rubber including its use as crumb rubber modifier in asphalt pavement. This study aims to investigate the effect of crumb rubber modifier on engineering properties of rubberised asphalt. The physical and rheological properties of rubberised asphalt binder that include different ...
Taxpayers save money by recycling asphalt. Contractors also save on transportation, energy and material costs. Other benefits of using recycled asphalt include reduce the demand for new asphalt that's more expensive, improved asphalt stiffness, and reduces the likelihood of cracking when used on pavements.
Asphalt shingles, whether manufacturers' waste or post-consumer shingles from asphalt shingle roof that been removed are high in asphalt cement/binder content. Shingles are easily processed and, like with recycling old asphalt mixes, the asphalt cement/binder is recovered and reused in new asphalt concrete mixes.
This paper studies the effects that varying amounts of waste cooking oil (WCO) and waste engine oil (WEO) have on the rejuvenation effect of aged asphalt, and the road performance of the 7% compound regenerant to different contents of RAP.
Cold Mix Asphalt (In-Place Recycling) The cold in-place recycling process involves specialized plants or processing trains, whereby the existing pavement surface is milled to a depth of up to 150 mm (6 in), processed, mixed with asphalt emulsion (or ed asphalt), and placed and compacted in a single pass.
Inside the Mizzou Asphalt Pavement and Innovation Lab, or MAPIL, located in the MU College of Engineering, engineers and students are determining how to incorporate various types of single-use, polyethylene-based plastic waste into asphalt pavement, …
Asphalt Pavement. While recycled asphalt pavement was not reported separately in these data, generation of "inert solid waste," which consists of concrete, asphalt, dirt, brick and other rubble, was conservatively estimated at 8.2 million tons. The estimated recycling rate for inert solid wastes was 57 percent; the remainder was disposed of.
Construction and Demolition (C&D) debris is a type of waste that is not included in municipal solid waste (MSW). Materials included in the C&D debris generation estimates are steel, wood products, drywall and plaster, brick and clay tile, asphalt shingles, concrete, and asphalt concrete. These materials are used in buildings, roads and bridges ...

Asphalt recycling leverages old asphalt and the market continues growing for a few simple reasons. Recycled asphalt provides a better product at a lower cost! Additionally, as a recycled product, municipalities and companies deliver an …
Asphalt is part of a recycling category called "construction and demolition" (or C&D) waste. Concrete, wood, glass and building fixtures are also considered C&D waste. C&D waste is typically treated differently from normal waste, which means it can be more difficult to find recycling centers.
California's Department of Resources Recycling and Recovery estimated that asphalt-rubber paving consumed more than 35,000 metric tons of crumb rubber in 2018.
The most common disposal method for asphalt shingles in the US is to dump them into landfills. Approximately 11 million tons of asphalt shingle waste is generated each year in the United States. The main environmental concern in recycling asphalt shingles is the rare presence of asbestos in shingles manufactured before 1980.
Roofers and contractors who sign on to the Commission's shingle recycling program receive reduced disposal costs on loads of clean asphalt shingles. There are several guidelines roofers and contractors must meet in order to receive the reduced tipping fee. Contact the Scott Area Landfill, mail@wastecom or 563-381-1300 for more information.
