Recycling of Asphalt in Germany

Experience with RA in Germany since more than 30 years

binder courses with PMB with the requirement of an equivalent binder in the complete mixture

since 1996 < 20 % share of RA

since 2005 < 40 % share of RA

new hotmix production that contains reclaimed material ~ 97 % (in 2012)

Open Questions

Softening Point (R&B)

• 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?

Page 32: PMB AND RECYCLING - vejforum.dk · 12/7/2016 · Evolution of PmB RC production 2014 25/55-55 A RC 21 % 25/55-55 A RC+ 12 % 25/55-55 A 67 % 2011 25/55-55 A RC 19 % 25/55-55 A RC+

PmB and Recycling - T. Sandmann, TOTAL - Vejforum 2016/12/07 32

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
