| Description | Arm-R-Shield bitumen-rubber was first introduced to South Africa in late 1982. This concept was radical in respect of the type of product, its manufacture and the very high application rates at which it was spray applied. Technical as well as application data from the USA was based on empirical information. Test methods as well as what characteristics of the binder were important had to be established. Of prime importance was the correlation of laboratory test data and the actual performance of the binder on the road. This paper reviews various full-scale usage of the modified binder in various climatic areas of the RSA and their performance to date. Specification limits are suggested in respect of resiliency, spray temperatures, flow, softening point and viscosity. Binder characteristics are also classified in order of importance for the optimum performance of roads with a reflection crack problem. |
