POLYMER MODIFIED ASPHALTY vonne Becker, Maryro P. M ndez and Yajaira Rodr guezConsidering the international position of Venezuelanoil industry as one of the leaders of the current worldasphalt production, it is important to be aware of thesource of opportunities that POLYMER MODIFIED ASPHALT (PMA) offers in today s market. Based on that, this paperpresents an overview of the characteristics of POLYMER - ASPHALT binders, mostly used in the paving is being made on the relationships of composi-tion and formulation with the properties of the binder,and the relationships of the binder properties andperformance of the mixture. Although POLYMER modifi-cation seems to be the best solution to improve asphaltproperties, these systems present three main problems: a)poor ASPHALT POLYMER compatibility (which influences thestability of the system), b) higher viscosities during asphaltprocessing and application, and c) higher cost.

VISION TECNOLOGICA / VOL. 9 Nº 1, 2001 41 Table 1 shows a summary of these polymers and their advantages and disadvantages as asphalt modifiers.
