What is the Requirements of Good Bituminous mixes

Requirements of Bituminous mixes Bituminous mixes Stability Stability is defined as the resistance of the paving mix to deformation under traffic load. Examples of failure under stability  Shoving : A transverse rigid deformation which occurs at areas subject to severe acceleration. Grooving :Longitudinal ridging due to channelization of traffic. Stability depends on the inter-particle friction, primarily …
