Why hot material needs laying promptly
Hot asphalt and macadam start to cool as soon as they leave the plant, and they need to be laid and compacted while still warm enough to bed in and bond properly. That means timing a delivery to match when you are ready to lay, rather than ordering material to sit on site.
Cold lay material works differently. It is designed for small repairs such as potholes and does not need laying hot, which makes it useful when a full hot lay job is not practical.
