Features of the Process of Loading and Transportation of Hot Asphalt Concrete Mixture. Ukrainian Experience

Abstract

Depicted in the Article are two stages of technological construction processes for asphalt concrete courses, namely: loading and transportation of asphalt concrete mix. As regards the loading, presented in the Article are two versions of discharging directly into dump body of dump truck or into storage hopper. Mentioned are the advantages of storage hopper usage, as well as the variety of such facilities and the storage time for asphalt concrete mix inside them. Described is the preparation procedure for a dump body of dump truck prior to loading (cleaning, lubrication). Explained are both the proper and improper schemes of loading, as well as the visual signs of asphalt concrete quality after discharging. Described is the right way to protect the asphalt concrete mix against cooling in dump body of dump truck, as well as the proper distance and allowed time-interval for transportation, possible problems occurring during transportation, expediency of using re-loaders for discharging the mix into the receiving hopper of asphalt paver
