Properties of a good bituminous mix :
- Stability
- Durability
- Flexibility
- Skid resistance
- Workability
Stability

Durability
It is the resistance of the mix against weathering and abrasive actions. Due to weathering bituminous mix gets harden which is due to loss of volatiles and oxidation. The tensile strain is develop cracks or plastic failure due to wheel loads and excessive strain
Flexibility
Flexibility measures the level of bending strength of bituminous mix.
Skid Resistance
It is the resistance of the finished pavement against skidding which depends upon the surface texture and bitumen content of mix. If the bitumen content is more, the surface of the pavement is smoothen or slippery. Therefore the bitumen content must be optimum to have better skid resistance.
Workability
It is the ease with which the mix can be laid and compacted to maximum density. It is the function of gradation of aggregates, their shape and texture, bitumen content and its type.
