Mix transport can have a large impact on flexible pavement construction quality and efficiency. Mix characteristics such as laydown temperature, aggregate segregation, and temperature differentials are largely determined by transport practices. In general, there are three types of HMA transport trucks: the end dump, bottom (belly) dump, and live bottom dump (flo-boy). End dump trucks are most common; however, bottom dumps and live bottom dumps are well-suited for certain situations. Key considerations in mix transport are:

If properly managed, mix transport can successfully move HMA from the production facility to the paving site with little or no change in mix characteristics. Material transfer devices/vehicles can assist in re-establishing mixture uniformity on site.
