Renewable Materials Based Bioasphalt – Scale-up and Performance Testing(23603)

United Environment and Energy LLC


Petroleum-based asphalt is widely used in road and other infrastructure construction. In an asphalt mix plant, the asphalt and aggregate are generally heated to ensure that the aggregates are fully coated by the asphalt to produce hot mix asphalt (HMA). It takes approximately 300,000 BTUs to heat 1 ton of HMA, which is equal to about 87.9 kWh of electricity. Each year, about 0.15 quadrillion BTUs are consumed in asphalt plants in the U.S. This is in addition to the energy used to produce asphalt in refinery plants. Moreover, the use of the petroleum based asphalt produces odor and volatile organic compounds (VOC) emissions. Funded by NYSERDA, UEE conducted a Phase I feasibility study on a novel bioasphalt production technology from waste cooking oils and coal-fired power plant fly ash. The study demonstrated that an energy efficient, environmentally friendly, and low cost renewable bioasphalt could be produced in a large quantity.

Project Description

This proposed Phase II project will focus on bringing this viable new technology from a laboratory scale to a pilot scale process, determining the optimal pilot plant operation conditions for bioasphalt production, evaluating the bioasphalt performance by asphalt producers and end-users, conducting a bioasphalt production cost and a hot mix life cycle cost analysis, and quantifying the bioasphalt energy benefits.


The success of this technology will lead to the development of a clean bioasphalt product. It will make the hot asphalt mix production process cleaner, energy efficient, and cost effective. It will also provide revenue for coal-fired power plants and provide financial support for cleaner energy production. The application of renewable material-based bioasphalt for highway and other infrastructure construction will ensure sustainable development in the asphalt industry, reduce energy consumption, and benefit New York State and the nation through energy independence.
