Summary

Introduction. The current state of the network of public roads due to the negative impact of climatic factors and ever-increasing traffic loads characterized by significant amounts of deformation and destruction of the road structure so requires significant material costs for maintenance and gradual improvement of a transport and operational condition according to the operating regulatory requirements.

Problem Statement. One of the promising areas to reduce the cost of road construction is manufacturing the recycled hot mix asphalt based on milled asphalt, which is usually formed in scarifying of the road surface layers during repair and construction works, with the plastic fiber addition obtained from household plastic waste. This combination of secondary materials will not only get the economic effect of reducing the cost of purchasing new road construction materials but also improve the environmental situation through the use of household waste.

Purpose. Investigation of physical and mechanical properties of recycled hot mix asphalt based on milled asphalt with the plastic fiber addition

Materials and Methods. It was established the manufacturing possibility of recycled hot mix asphalt based on milled asphalt with the plastic fiber addition. Test specimens performance measuring was conducted to determine the average density of the material, water saturation, swelling at ultimate compressive strength in the laboratory conditions according to standardized techniques by current regulations.

Results. The results of experimental studies regarding the manufacturing features and physical and mechanical properties of recycled hot mix asphalt based on milled asphalt with the addition of plastic fiber obtained from household waste are shown.

Conclusion. The correspondence of the manufactured specimens of recycled hot mix asphalt to regulations is established as well as its road construction application options.
