Materials | Description |
Virgin aggregates | Quartzite sandstone with a continuous gradation (0 - 5 mm) |
Bitumen Emulsion | A quick setting cationic bitumen emulsion (60% binder content and 40% water content) named CQS-1HP, complying with ASTM standards; |
ADP1 | An adhesion agent specific for micro-surfacing, containing N-tallow propylene polyamines mixed with hydrochloric acid and dispersed in 10% of water by mass. Its purpose is to control the breaking of the emulsion; |
Cement | CM II 32.5 R cement, to control the breaking of the emulsion; |
Reclaimed Asphalt Pavement (RAP) | The RAP has the same gradation as the virgin aggregates (0/5 mm) with a bitumen content of 4.6%; |
Glass fiber | Glass fibers from the United States. These fibers were used in recycled Micro-surfacing manufactured with more than 20% of RAP in order to improve the cohesion between the binder and aggregate. The content of fiber is of 0.1 % and the length of the staple fibers is about 1 mm. |
