Abstract

The article presents the impact of a polymer modifier (P) on the properties of mineral-cement-emulsion (MCE) mixes. The theoretical part of the article discusses the ways of producing mixes using deep cold recycling. The “in-place – on site” and “in-plant – delivered” production methods are described. The paper also presents a description of a redispersible polymer powder (RPP) used as the polymer modifier. The part dedicated to the conducted research presents the experiment design and discusses the research methodology used to evaluate the effect of the polymer modifier on the properties of the MCE mix. The project involved the production of MCE mixes varying in terms of the type and amount of polymer powder, cement and bitumen emulsion. Mixes were designed with a variable share of cement range from 0.5% to 3.5%, a share of bitumen emulsion ranging from 0% to 5% and a fraction of redispersible polymer powder from 0.5% to 3.5%. A total of 15 mixes were made as part of the experiment, designed according to the Box-Behnken experiment design. The following physical and mechanical properties were assessed in the plan of the research: air void content Vm, water absorption nw, indirect tensile strength ITS, water damage resistance TSR, IT-CY stiffness modulus and SCB fracture toughness. The test results were analysed to assess the impact of the redispersible polymer powder on the properties of the recycled MCE mix. Following the analyses, the composition of mix was optimised regarding the requirements set out in the Polish design guidelines.
