Hot boxes, also known as an asphalt hot box or road repair hot box, is a specialised piece of equipment designed to store, transport, and maintain the temperature of asphalt for road and pothole repair applications. Whether you’re patching highways, fixing urban streets, or conducting small-scale maintenance, a hotbox ensures that the asphalt stays at the required working temperature—typically around 140–160°C—for maximum usability and performance. Dawsongroup offer hot boxes for hire and also ex fleet hot boxes for sale too,

  • Diesel or propane heating systems
