Concrete Sleeper - an overview | ScienceDirect Topics

The first kind of RAC was designed with RA from crushed out of service concrete sleepers (RC-S), the second one with RA from crushed out of service railways ballast (RC-B), and the third one with a mixture of these two types of aggregate (RC-M). The RC-M was defined as 6/7 of RC-B and 1/7 of RC-S, which is the general ratio between sleepers and ...
