User's Guide: Double Bituminous Surface Treatment
Hot asphalt cement, used on most jobs, attain the temperature of the substrate to which it is applied in a few seconds. If the substrate is cold, the asphalt cement hardens almost immediately and will not grip the aggregate. Asphalt emulsions must "break" or change into asphalt cement by evaporation of the water before it can bond

Nitro efficiency index (Asphalt 8)
Nitro efficiency is defined as how much of a full single Nitro tank (as a percentage) is consumed per second. For example, a Nitro efficiency of 12 means that 12 % of a full tank is drained per second and that it would take roughly 8 (100/12) seconds to empty a full tank.. Hence, numbers closer to zero denote longer-lasting nitro. Nitro efficiency is independent of a vehicle's nitro …

Bituminous Surface Treatments – Pavement Interactive
Bituminous surface treatments (BST) refer to a range of techniques that can be used to create a stand-alone drivable surface on a low volume road, or rehabilitate an existing pavement. Usually, the term is used to describe a seal coat or chip seal, which is constructed by spraying a layer of emulsified asphalt, and placing a layer of aggregate on top.
