  • Patent number: 8765847
    Abstract: Methods are provided for upgrading the quality of an asphalt. The methods include mixing an asphalt feed with a cracking resistance additive that improves the low temperature properties of the asphalt while leaving the high temperature properties unchanged or minimally changed. The cracking resistance additive corresponds to a compound that is a liquid at both the low temperature performance grade for the asphalt and at mixing and/or storage temperature for the asphalt. Examples of compounds that, in an appropriate molecular weight range, are liquids across this broad temperature range include polyalphaolefins, alkylated naphthalenes, and organic esters.

  • Publication number: 20140128515
    Abstract: A process of preparing a polymer modified asphalt (PMA) comprising mixing a predetermined amount of a polymer-asphalt master batch with a predetermined amount of an asphalt-cross linking agent blend. The polymer-asphalt master batch comprises at least one polymer and a first asphalt. The asphalt-cross linking agent blend comprises a second asphalt and at least one cross linking agent. A predetermined amount of the polymer-asphalt master batch is blended with a predetermined amount of the asphalt-cross linking agent blend to form a PMA blend. Mixing of the PMA blend is performed without substantial delay following blending of the polymer-asphalt master batch with the asphalt-cross linking agent blend.

  • Patent number: 8697781
    Abstract: The invention relates to a process for the preparation of mixtures containing bitumen and thermoplastic polymer at a high concentration, stable during storage, with particular characteristics of easy processability and movability which, once diluted, allow modified bitumens to be obtained with high performance characteristics. In particular, the process allows mixtures containing bitumen, thermoplastic polymer and wax, to be prepared, wherein the polymer is in a quantity varying from 5 to 30% by weight with respect to the weight of the mixture consisting of bitumen and polymer, and the wax is in a quantity varying from 4.7 to 16.7% by weight with respect to the weight of the total mixture, and comprises reacting a concentrated mixture (A), stable during storage, containing bitumen and from 5 to 30% by weight of thermoplastic polymer, with a hydrocarbon wax containing at least 40 carbon atoms and having a melting point of at least 700 C.

  • Patent number: 8679244
    Abstract: Disclosed is a modified asphalt composition including a styrenic block copolymer and a vegetable wax as modifier. With lower viscosity at high temperatures as compared to the asphalt composition modified only with the styrenic block copolymer, it can be manufactured and used at lower temperatures. Also, with higher ductility at low temperatures, it can minimize fatigue crack even in cold weathers.
