Abstract:

This paper presents the results from the tests performed on the recycled base mixes manufactured in cold deep recycling technology with bitumen emulsion and different types of binding agent. Portland cement denoted as CEM I 32.5, lime and the blends of both were used. The mineral mix design was based on the recycled material derived from the local road renovation. The material consisted of recycled bituminous layers and base unbound aggregate. For the purpose of evaluating an influence of the binding agents, the tests were to determine indirect tensile strength (ITS), indirect tensile modulus (Sm) at specific temperatures of 0 degrees C, 10 degrees C and 20 degrees C and water and frost resistance of the recycled base mixes. The results obtained from the tests indicated that the impact of the tested binders on the properties of recycled base varies. In addition, a beneficial influence was observed of a little amount of lime in binder blends on water and frost resistance of the recycled base. The paper provides a preliminary assessment of the amounts recommended for application.
