process sequencing LEA® 2

Phase 1      The coarse aggregates and part of the sand are heated to about 130°/150°C

Phase 2/3   The rest of the wet and cold sand or/and RAP  are then introduced into the mixer, Water is added if required

Phase 4      The bitumen in introduced at its température around 170°C. The bitumen coats the coarse aggregates and the bitumen foam  is also produced that coats the sand preferentially

Phase 5      The coating is completed and temperature settles below 98°C

Phase 6      The remaining steam condenses to give the LEA 2 mixes the workability needed for lay on

The water content of the mix is around  0.5%.
