Feasibility Study Using New High Modulus Additives in High Modulus Base Mix in Algerian East-West Expressway Project

This paper reports a study comparing four additives used to produce high modulus pavements of which one is an accepted product normally used in France. The other three additives are newly developed products that have been used in China pavement practice, however, without following the French specification. This research evaluated the feasibility of using the new additives to produce acceptable high modulus mixtures. Mixtures were produced with different additive contents, and their performances were evaluated and compared using the wheel track test in accordance with the Chinese method T 0719, and the modulus and fatigue tests in accordance with NF EN 12697-26 and NF EN 12697-24, respectively. The test results showed that mixtures produced with the new additives had similar performances as the accepted French product. In fact, some new mixtures even displayed properties superior to those produced with the French product. Therefore, some of the new additives evaluated in this study could be accepted for use as an optional choice in high modulus mix design.
