An improvement to a chassis for mobile asphalt plants consists in modularizing the design of the chassis in order to reduce design time and storage costs by virtue of a standardization of the chassis. Thus, the solution fits asphalt plants of different sizes and reduces the physical space required to store items belonging to the structure of the chassis. The high level of standardization has been achieved by segmenting the main structure of the chassis into three regions which appropriately accommodate all of the systems for producing the asphalt mixture.
