Resumen
Fatigue cracking is the significant distress caused due to the repetitive axle loads combined with environmental conditions on flexible pavement surface. Commonly bituminous concrete used as surface course mixes produced with unmodified bitumen a viscoelastic material and temperature susceptible. It is also prone to permanent deformation under repeated axle loads. The modified binders are more stable under fatigue loads, braking and accelerating forces and thus show increased resistance to permanent deformation even in hot weather. This paper discusses the fatigue behaviour of nano-clay modified bituminous concrete by repeated load test results such as resilient modulus and tensile strain.
