Research in this application is at its very early stages and as such many assumptions need to be made in volume calculations. The percentage of polymer in asphalt sealants varies from 7 to 20% (King and King 1988). With an assumption that 50% of polymer can be replaced with WLP; the WLP percentage in asphalt sealant will be 3.5% to 10% (average of 7% is used in calculations). Table 13 shows rough estimations on WLP quantity required to replace 50% of polymer used in asphalt sealants. Table 13 Volume considerations for WLP in concrete and asphalt selanats Annual production Replaced Required WLP Application (thousands m3) (Australia) polymer (tonnes) Asphalt Sealants Up to 50 34 kg/m3 1700 Environment Impact Assessment of WLP in Concrete This section provides an overview of the major environmental impacts and considerations Understanding the associated with recycling WLP in concrete and also asphalt sealants. environmental impacts of each option helps in making informed decisions on whether or not to proceed with a project.
