Statement of the problem. Studies of the degree of influence of the content of polymer-modified bitumen, adhesive additives and mineral materials of various rocks on the physic-mechanical and operational properties of draining asphalt have been conducted. Results. The results of the mathematical planning of a three-factor experiment are presented in the process of studying the operational properties of porous asphalt. Conclusions. The composition of the draining asphalt mix on mineral materials of various types and types of rocks and polymer-modified bitumen PMB 50/70 with an adhesive additive that provides an increase in the abrasion service life, reaction rate and water resistance has been developed and justified.
