for Compaction Machine Operators

Training keeps compactor crew sharp

T he most elemental meaning of the word “ compaction ,” is the exertion of force on something so that it becomes more dense .

In the realm of road construction , compaction is considered one of the most important processes in pavement surface construction . It is necessary in order to attain high-quality and uniformity of pavement materials , which in turn better ensures the long-lasting performance of the paved surface .
It has been more than a few years since the term and method of “ intelligent compaction ” ( IC ) has become a given in discussions of roadway paving . Today , it has become the norm -- compaction is pretty much considered intelligent compaction . Yet , no matter how “ intelligent ” and technologically sophisticated the machine has become , the crucial performance

results are still the responsibility of the compactor operator . The paving project success and the pavement ’ s long-term performance can rest in the skills of the compaction machine operator .
“ Roller compactor operators need to understand their primary function in the paving process , since asphalt compaction is the final step in laying down quality pavement ,” Eric Booth , product training / marketing manager , Sakai America , Inc ., Adairsville , Georgia . “ They need to be observant in order to monitor their roller … looking at asphalt temperature , how much water is in the tank , is the DEF ( diesel exhaust fluid ) tank full , what is the status of the DPF ( diesel particulate filter ), is any asphalt picking up on the drums , etc . The plant , milling machine and paver can do everything correct , but if the roller isn ’ t on the mat at the right time or is ignoring general maintenance , this can cause density issues that lead to
