Khursheed U.S. Environmental Protection Agency Office of Air Quality Planning and Standards Innovative Strategies and Economics Group MD-15 Research Triangle Park The primary use of asphalt/bitumen is in road construction, where it is used as the glue or binder mixed with aggregate particles to create asphalt concrete. Its other main uses are for bituminous waterproofing products, including production of roofing felt and for sealing flat roofs.

The 3 Most Popular Uses for Asphalt Asphalt concrete material is made up of 5% asphalt or bitumen cement and 95% stone, gravel, and sand. Asphalt's primary use is for paving roads. There are other applications, but flexibility of the material makes it a commonly

SHRP-A-650 Summary of Health Practices: The Use of Petroleum Asphalt in the Hot-Mix Paving Industry R. Marcus Barksdale, M.S. James Scherocman, P.E. SHRP-A-650 Contract A-001 Program Manager: Edward T. Harrigan Project Manager: Edward T. Harrigan

asphalt pavements (RAP) with a recycling agent to chemically restore the aged asphalt binder. Waste engine oil from automobiles has been shown to improve asphalt binder when applied in small quantities, with the added advantage of being a waste product itself.

Warm-mix technologies fall into three basic categories; one uses a small quantity of water to create foaming of the asphalt, another uses a chemical additive, and the third uses an organic additive. These technologies result in a mix that can be placed on the roadway at reduced temperatures.

Polymer Modified Asphalt

The primary benefits include resistance to rutting, less thermal cracking, and overall improved durability in the face of traffic and other environmental wear and tear. Whether it's a need for jet fuel resistant pavement or asphalt to resist the stresses of reflective cracking at pavement joints, we have the supply available to meet your needs.

2014/10/20The aggregates are separated into two different structures: primary structure, the load bearing one, and secondary structure, smaller material that provides stability to the skeleton. A coating thickness for these two structures is calculated from a geometrical consideration that includes the packing arrangement of particles and the effect of overlapping as the film grows.

A prime coat is an application of a low viscosity asphalt to a granular base in preparation for an initial layer (or surface course layer) of asphalt. The purpose of the prime coat is; to coat and bond loose material particles on the surface of the base, to harden or toughen the base surface to provide a work platform for construction equipment, to plug capillary voids in the base course

Soil constitutes the primary material for the foundation, subgrade, or even the pavement (for low-cost roads with low traffic in rural areas). When the highway is constructed on an embankment at the desired level, soil constitutes the primary embankment material; further, since all structures have to ultimately rest on and transmit loads to 'mother earth', soil and rock also serve as

Asphalt is the most versatile and flexible paving material in the world making it the preferred paving material for numerous pavement applications. The facts speak for themselves, of the more than 2.2 million miles of paved roads in the United States; over 94 percent of them are surfaced with asphalt.
