Influence of Temperature on the Performance of Bituminous Pavements
In this technical note, we describe the influence of temperature on the performance of bituminous pavements. Temperature significantly influences bitumen properties throughout its lifecycle - from its production at the refinery to its service life on the field. This article discusses the properties of bituminous pavement with particular reference to the following topics:
Production process
Mixing and compaction of bituminous mix
Aging and
Mechanical response of bituminous mix.
The paper also explains why the existing technical specification system for bitumen followed in India may not capture such complexities.

Backgroud
India has the second largest road network in the world measuring about 3.3 million km length in 2011 (NHAI, 2012). This includes unpaved and paved roads. In terms of density of paved roads this accounts for 0.07 km per 1000 people. Considerable financial outlay is earmarked by the country in constructing or improving the existing road network.
