Mechanical Properties of 100% Recycled Half-Warm Asphalt Mixtures
Original language description
In several countries bituminous mixtures are used in railway subballast instead of crushed stone because of their greater resistance to permanent deformation, durability, impermeability and better thermal insulating properties. Since the production of hot mix asphalts requires great amounts of energy and natural materials, a solution utilizing recycled asphalt pavement (RAP) only and demanding less energy was proposed and investigated. 100% recycled half-warm asphalt mixtures (H-WMA) were produced by heating RAP up to 100 ±5 °C and were placed over a soft subgrade in a full-scale laboratory model of railway trackbed. After 500 000 loading cycles, specimens were taken from the bituminous layer to assess, whether any deterioration of the recycled H-WMA occurred due to the cyclic loading and to evaluate the mechanical strength of the mixtures as well as their resistance to water and frost. The tests revealed satisfactory mechanical strength and resistance to water and frost of the mixtures.
