The primary pollutants of concern from asphalts and asphalt paving operations are volatile organic compounds (VOC). Of the 3 types of asphalts, the major source of VOC is cutback. Only minor amounts of VOCs are emitted from emulsified asphalts and asphalt cement. VOC emissions from cutback asphalts result from the evaporation of the petroleum.
CHAPTER 17 - ASPHALT PAVING 1/31/01 2 Telephone conversation between R. Benson of the Asphalt Institute and S. Buchanan, Eastern Research Group, Inc., September Volume III Hot-Mix Asphalt Hot-mix asphalt is the most commonly used paving asphalt for surfaces of 2 to 6 inches thick.
GHG emissions of over 20 different paving product types by ton of material placed. Their comparisons show that PCC paving materials and processes demand the most energy, followed by hot mix asphalt (HMA) paving. The report also showed that cold in-place recycling (CIR) is the least energy intensive process.
Dorchies ()File Size: KB. Evaluation System Boundary. This study focuses on GHG emission from the raw material production and pavement construction, as shown in Figure includes the emissions from all components of the asphalt pavement, including the extraction of raw materials, transport and the onsite placement of the asphalt by: Hot mix asphalt is used primarily as paving material and consists of a mixture of aggregate and liquid asphalt cement, which are heated and mixed in measured quantities.

Asphalt is a dark brown to black, cementlike semisolid or solid produced by the nondestructive. We therefore request that Paving Asphalt Emissions are evaluated separately from roofing asphalt emissions for prioritization.

The majority of emissions at asphalt mixing facilities come from the combustion of fuel, such as natural gas, that are used to dry and heat the rock or aggregate and to keep the temperature of the asphalt hot.

Pavement and Has a Place in Livable Communities. Long before “sustainability” entered the layman’s vocabulary, the asphalt industry was supporting research and field studies to ensure that asphalt pavements and paving practices were environmentally friendly. Asphalt plants produce very low emissions.

With respect to the compaction effort, there seemed to be no discernible difference in. Hurley, G., “Evaluation of New Technologies for Use in Warm Mix Asphalt,” Master’s Thesis, Auburn University, Auburn, AL, August Hurley, G.

Emissions from asphalt plants, including greenhouse gases, are very low and well-controlled. Between andthe asphalt industry decreased total emissions by 97 percent while increasing production by percent.
