Emergency services were called at 9.15am to to deal with the accident.
The driver escaped unhurt.
However, the incident left the London-bound motorway closed from Junction 12 to 10 for most of the day, with junctions 10-11 remaining blocked.
Folkestone fire crew was among those attending the incident.
They returned to their base only to be called back at midday as some material was spontaneously combusting.
