Open Questions Softening Point R&K Do we need an upper limit or we lack only an appropriate test method for addressing the low-temperature properties? Use of softer binder Analog procedure for PmB as for the road bitumen when using asphalt granulate? PmB and Recycling - T. Sandmann, TOTAL - NABin October 20th 2015 38
Conclusion Specially formulated PMB-RC types allow a share of RAP from 40-50% PmB-RC-made asphalts are equivalent to those with exclusively fresh binder PmB and Recycling - T. Sandmann, TOTAL - NABin October 20th 2015 39
