The research on the selection of the binder for use in the composition of the colored polymer concrete. The basis of the binder is done petroleum resin, wherein the plasticizer used as an industrial oil. Consider the following characteristics of the binder: visual assessment of the binder, the depth of penetration of the needle in mm, the softening temperature of the ring and ball at 0 C, extensibility in cm. With the introduction of industrial oil in a preheated to operating temperature petroleum resin transparency of complex binder significantly decreased, while were achieved characteristics similar to those of bitumen. Exploring the possibility of application of the finished binder as the binder for colored polymer concretes, however considered binder at normal temperature has a fluid consistency, its use in the composition of the colored polymer concrete is impossible. The composition of binder has been modified by the introduction of a petroleum resin, were achieved with mechanical properties similar to the properties of bitumen. In connection with determining the coefficients of all the components of transparency, transparency binder corresponding to the characteristics of bitumen, above all visually selected compositions.
