Description
Technical Field
The invention belongs to the technical field of road construction material transportation, and particularly relates to cold-paving asphalt mixture transportation equipment and a transportation method based on the equipment.
Background
The traditional hot-mix asphalt mixture needs to be mixed and paved at high temperature, and is inconvenient to apply. Unlike hot mix asphalt mixtures, cold-laid asphalt mixtures can be stored, transported, and laid in a low temperature environment. Common cold-paving asphalt mixtures in China comprise epoxy emulsified asphalt mixtures, HU-L cold-paving asphalt mixtures, LB cold-paving asphalt mixtures, hengta brand road cold-paving asphalt mixtures and the like.
Dump trucks are commonly used road construction material transportation vehicles. However, when the transportation conditions are drier, water loss is accelerated, resulting in demulsification of the emulsified asphalt (a component commonly used in cold-laid asphalt mixtures). When the stack is too high, moisture and fines deposit on the bottom and are easily segregated. Meanwhile, the mixture at the bottom layer is agglomerated due to the action of gravity, which is not beneficial to construction.
