The paper investigates the factors affecting the effectiveness of cold recycling technology for road repair. The authors have investigated the effect of asphalt granuloconcrete composition on indirect split tensile strength and water resistance coefficient. The authors applied the method of response surface order estimation in orthogonal planning for two factors. The arguments of bar diagrams with numerical values of the function and applications are given on the plan view. Using the deformable simplex method, the authors constructed and characterised the expected three-dimensional shape of the response surface. The results minimise the time required for design work in road construction and achieve significant savings on materials and labour.
