Road Cement Concrete with Lime Aggregate

The use of local aggregates of limestone nature for the producing of road cement concrete leads to obtaining numerous technical - economic advantages. Romania owns great limestone resources (over 3 milliards tons with an ensurance degree up to 999 years) smoothly spread over the entire surface of the country. In this paper there are presented the results of the laboratory and the field researches and also, the experiments carried out on limestones and concretes with limestone, in comparison to the concretes produced with aggregates of silicon or eruptive nature, for establising the influence of the limestones aggregates upon the characteristics that are specific to the road cement concrete.
