Processing bituminous mixtures for paving at reduced temperatures
Abstract:
Bituminous paving mixtures containing lubricating agents or additives may be prepared at hot mix temperatures and cooled, paved and compacted at temperatures 10-55 Celsius degrees lower than the hot mix temperatures. The increased temperature range between the hot mix temperatures and the paving and compacting temperatures is facilitated by the improved compacting properties of the paving mixture when it includes the lubricating agents or additives.
