No, bitumen modification is not suitable with all types of plastics. Only certain polymers that soften, swell, or partially dissolve in bitumen can form a stable PMB system. In practice, SBS, EVA, PE, and some polyolefin wastes are used, while plastics like PVC, PET, or highly crosslinked thermosets are unsuitable because they decompose, release gases, or remain as solid particles. The key factors are thermal stability, compatibility with bitumen fractions, and ability to form a homogeneous phase under mixing conditions.
