Definitions

  • tall oil, a strong base, and (a) polymer(s) are added to an asphalt cement simultaneously or substantially simultaneously.
  • This blend is subjected to shear by a colloid mill or mixer, or both, to assist in the reaction and incorporation of the materials into the asphalt cement.
  • the polymer(s) selected is (are) in the form of (a) latex(es)
  • the water in the latex(es) may be used to start the reaction of the tall oil and strong base.
  • Example 21 the polymer is a natural latex. This modification increased the 60°C viscosity, softening point, resistance to flow and improved the PVN.
  • Example 22 the polymer is an ethylene methyl acetate (EMA) .
  • EMA ethylene methyl acetate
  • This modification increased the 60°C viscosity and improved the PVN, but did little else. It was expected to improve the low temperature flexibility (ductility) , but it did not with this particular asphalt cement.

Abstract

Des ciments au bitume modifiés comprennent du ciment au bitume, du tallol, du brai de tallol, des dérivés de tallol ou des mélanges de ces derniers mis en réaction, ainsi que des polymères choisis à partir de copolymères séquencés et des latex, à la fois synthétiques et naturels. Différents procédés de fabrication consistent à mélanger un ciment au bitume modifié/tallol mis en réaction avec un ciment au bitume modifié par polymère pour obtenir les caractéristiques requises; modifier un ciment au bitume avec un tallol, du brai de tallol, des dérivés de tallol ou un mélange de ceux-ci, mis en réaction, et ajouter ensuite le ou les polymères choisis à ce ciment au bitume modifié/tallol; modifier le ciment au bitume avec le ou les polymères chosis, et ajouter ensuite le tallol, le brai de tallol, les dérivés de tallol et les mélanges de ceux-ci, et les mettre en réaction avec une base forte; et ajouter le ou les polymères, le tallol, le brai de tallol, les dérivés de tallol et les mélanges de ceux-ci, ainsi que la base forte au ciment au bitume en même temps ou presque en même temps.
