 Asphalt Paving Mixture
Aggregates are blended, heated, dried, and mixed with asphalt cement to produce a hot asphalt paving mixture. There are two types of mixing facilities currently in widespread use.
They are the Batch Mixing and the Drum Mixing facilities. Operations of a batch mixing facility include:
- Cold aggregates storage
- proportioning
- drying / heating
- screening
- hot aggregate storage
- measuring and mixing of aggregate and asphalt,
- discharge into truck, storage silo or surge bin.
Aggregates are removed from storage or stockpiles, in controlled amounts and passed through a dryer, where are dried and heated. The aggregates are then passed over a screening unit that separates the material into different size fractions and deposits them into bins for hot storage. The aggregate and mineral filter, are then withdrawn in controlled amounts, combined with asphalt and thoroughly mixed.
Operations of a dram mixing facility include:
- cold aggregate storage
- proportioning
- heating and mixing of aggregate and asphalt
- storage silo.
Our engineers have an in-depth understanding of the asphalt plant logistics and different pavement types –hot mix, cold mix and surface treatments – and their specific applications and limitations.
