Abstract
As a response to the negative impact of private companies on the quality of works and deadlines that carry out maintenance works for the National Roads, of the fluctuations of the economic growth in EU and Romania, with the correlation with the public funds allocated, National Company for Road Infrastructure Administration has decided to buy machinery and prepare its own staff for carrying out works of roads based on cold recycling solutions. The recycling solutions were mainly based on in place recycling with bitumen emulsion or foamed bitumen with Wirtgen recyclers type WR 240i. This paper presents the laboratory tests for the mix design and a few comparison for road layers that have been made by cold recycling in place with bitumen emulsion.
