Description

technical field [0001] The invention relates to the technical field of road asphalt, in particular to a compound, a warm asphalt, an asphalt mixture and a preparation method and application thereof. Background technique [0002] At present, there are two main types of asphalt mixtures used for asphalt pavement construction and maintenance: hot mix asphalt mixture and cold mix (normal temperature) asphalt mixture. Hot mix asphalt mixture refers to the mixture of asphalt and mineral aggregates mixed at high temperature (150 ° C ~ 185 ° C); cold mix (normal temperature) asphalt mixture refers to emulsified asphalt or dilute ℃ ~ 40 ℃) state mixing, paving mixture. Hot-mix asphalt mixture is the most widely used, but problems such as harmful gas emissions, excessive energy consumption, and thermal aging in the process of mixing, transportation, and paving are more prominent; while cold-mix asphalt mixture, despite environmental protection, energy consumption, etc. However, due ...
