Combinations in various proportions of milled bituminous concrete and crushed limestone aggregates were mixed in the laboratory with 5% by mass cement and 5% by mass water to simulate some of the materials that can be obtained when mix-in-place recycling with cement is used. The influence of the temperature and of the type of loading (different rates of stress application of ramp loading and different frequencies of sinusoidal loading) on the modulus of elasticity is examined. It is concluded that as the milled bituminous concrete content in the mix is increased, both the temperature and the rate of stress application increasingly influence the results, and this should be taken into consideration when specifying or designing pavements incorporating cement-bound materials of this type.
