Abstract

Although known for a long time, hydrated lime (HL) still attracts a strong technical interest as an asphalt additive. This presentation describes recent field results obtained in France in two dif-ferent contexts: - First, we describe the 7-yrs experience obtained on 20 sections with and without HL in the mountainous Vosges department. This eastern part of France is characterized by cold winters and significant elevation, making it a pretty challenging environment for asphalt mixtures. The types of mixtures were essentially semi-dense Asphalt Concrete (French BBSG). The results after 7-yrs of monitoring are described. - Second, we describe the 5-yrs experience obtained on 5 sections with and without HL in the oceanic climate of Highway A84 in Normandy. The types of mixtures were also semi-dense Asphalt Concrete (French BBSG) and a thorough testing program was established from the beginning. The results after 5-yrs of monitoring are described. As a result, the results allow quantifying the impact of HL in terms of dura-bility improvement.
