I am a roller operator in Quebec Canada . Working with Bomag Roller with steel drum . They just told me I will be working with a pneumatic big roller . Looking up youtube trying to find tips & tricks for roller compactor .

Great video.

This was informative, thank you.

Good vid, thanks

Machine weight and linear load are not the right parameters to predict the performance of a roller, for instance a 80 cm roller of 1575 kg (rolling factor 0.21) is stronger than a 213 cm tandemroller of 17 tons (rolling factor 0.12), the only difference is the production capacity. Tender zone is mainly caused by tandemtrollers, wide drums tend to compact in a more horizontal direction. Also the Nijboer factor is not a right tool to predict the behaviour of a roller drum. for thinner lift three wheel static rollers are the best choice. The rolling factor of a tandemroller is about 0.15, a rolling factor of a three wheel static roller is about 0.60, so four times stronger pressure! A big difference is the direction of compaction, three wheel roller compact in a more vertical direction, tandemrollers are pushing the asphalt more horizontally. The problem is that tandemrollers tend to destroy the density they previously gained. A lot of vibration is much too strong, it is better to use softer vibration and run some more vibratory passes. Be careful with vibration, drum ringing is a sign that the vibration is too strong. Vibration is not the only way to compact, it is useful when the mat is hot, but after two or three vibrating passes it is better to continue with static compaction. Be sure there are enough rollers!

Been to Texas and put down mix. Your mix is very different from ours here in Ohio.

Omg I love you

I work in Saudi Arabia . We drive caterpillar cw34. And

if you turn sharply on cold or old asphalt the asaphalt sticking on the tires or drums will come off also diesel works best for non stick tires not this water based bullcrap
