65 hour working week

I saw an job ad for a local tipper company a few weeks ago and can’t for the life of me understand it.

It read “£x.■■/hr for 48 hours, then time and a 1/2 thereafter, average hours 55-65 per week.”
The job involved shifting coal to power stations, etc and is paid right through, no deductions.

How is this possible?
If you can only do 45 hours driving time per week (averaged over 2 weeks, obviously) + a break of 45 minutes each day, that’s 48.75(?) hours working time per week. Now I can’t imagine there being much waiting to load/tip with this type of work, certainly not 6-16 hours worth over a week; unless I’m wrong and the the 55-65 hours is made up of other work, POA, etc.?
