Abstract:

The potential use of incinerator ash in asphalt concrete paving was evaluated. Laboratory tests were conducted on ash from a waste-to-energy incinerator. Tests were conducted to assess whether asphalt concrete mix with ash was suitable both in terms of physical performance and environmental safety. It was determined that a mix with acceptable parameters on the Marshall tests could be produced with an aggregate consisting of up to 32% incinerator ash. This mix requires a higher asphalt content than a normal mix and appears to be prone to stripping. The results of the toxicity tests on the leachate were inconclusive; however, they suggest that there might be a problem since a significant amount of lead was detected in the leachate. It was concluded that an asphalt concrete mix with ash might be suitable for use in base course or for low-quality surface applications. However, a significant quantity of undesirable material must first be removed to get an aggregate of acceptable quality. Only about one-third of the material in the bottom ash is suitable for use in an asphalt concrete mix.
