Abstract: The lime addition in the mix asphalt became nowadays an innovative technique in the field of infrastructure. The objective of the experiences is to improve the durability of roads, especially in the United States and in Europe. In Morocco, this aspect remains in the reflecting phase, a part from some simple experiences; this technique allows, from a precise dosage of lime, to increase the service life of roads, and to optimize the maintenances costs caused by the damages.

Abstract: The porous anode alumina (PAA) films on silicon substrate with good physicochemical properties have hopeful for the nano-scale devices. The various factors which influence the preparation of high performance PAA film based on silicon were systematically studied, the DC magnetron sputtering technology was used to deposit aluminum and the two-step anodic oxidation method to growth PAA membrane. The results demonstrated that about 2 μm aluminum film deposited on the p-type silicon substrate, in advance deposited 50 nm Ti film on the Si substrate, can get high quality Si-based PAA membrane with good adhesivity, stable structure and consistent pore shape and diameter.
