Hot mix asphalt cement is a material which has revolutionized road construction process.Hot mix asphalt paving consists of a combination of aggregates uniformly mixed and coated with asphalt cement. The term Hot Mix is used due to the fact that to dry the aggregates and to attain the desired degree of fluidity of the asphalt cement for proper mixing and
Bitumen is ‘cutback’ by adding controlled amounts of petroleum distillates such as kerosene. This is done to reduce the viscosity of the bitumen temporarily so it can penetrate pavements more effectively or to allow spraying at temperatures that are too cold for successful sprayed sealing with neat bitumen.

A note on terminology is worth making at this point – ‘asphalt’ is a generic term used to describe a range of road surfacing products containing primarily bitumen and mineral aggregates. A few alternative terms exist including hot mix asphalt (HMA) and asphalt concrete (AC). In this book the term ‘asphalt’ will be used throughout.
Although highway technology has changed markedly since, principal road layers still consist of a mixture of stone, in the form of graded aggregate, and binder, in the form of a petroleum bitumen or a derivative of petroleum bitumen. Engineers today have a wide choice of materials available for road pavement construction.
Rubberised Bitumen in Road Construction Page 1 Rubberised Bitumen 1. Summary This section deals with rubberised bitumen, a binder in hot mix asphalt and chip seal applications that results from the proper addition of crumb rubber to hot bitumen and then left in a heated state to react.
As a low temperature technique, using emulsified bitumen is also suitable for reducing emissions and energy consumption. The construction of a roadway with bitumen emulsion (cold-mix bitumen) is likely to consume approximately half the energy of paving a road with hot-mix bitumen.
