6.1 Introduction

Mix transport involves all actions and equipment required to convey HMA from a production facility to a paving site, including truck loading, weighing and ticketing, hauling to the paving site, dumping of the mix into the paver, windrow, or material transfer vehicle hopper, and truck return to the HMA production facility (Roberts et al., 1996). Ideally, the goal of mix transport should be to maintain mix characteristics between the production facility and the paving site. Transport practices can have a profound effect on mix temperature at the paving site, aggregate and/or temperature segregation of the mix, and mat quality. This section will discuss the types of trucks used for mix transport and the various considerations involved with mix transport.
