摘要： Plastic road plate of a cuboidal shape containing four transport through-holes with rectangular longitudinal-section, located near the corners of the plate; its thickness varies from 100 mm to 250 mm, and the plastic used is heterogeneous plastic waste - light and heavy plastics, a combination of lightweight and heavy plastics, PVC or rubber from used tyres. Method of manufacture of the plastic road plate, characterised by the fact that the plastic used is plastic waste; the method consists of the following stages: a) shredding of plastic waste; b) pre-washing of plastic waste; c) production of plastic mass by melting plastic waste chosen from the group composed of lightweight and heavy plastics, their combination, PVC, or rubber from used tyres in a temperature varying from 150 to 280°C and injecting the aforementioned plastic mass to a previously prepared mould tilted at angle α towards the ground, where α equals 15-35°; d) solidification of the moulded plastic plate.
