Investigations on the control of reflective cracking in flexible pavements using geosynthetics

The overlay installation above the cracked pavements is a quick fix accepted globally. The rehabilitated pavements under repeated traffic and thermal loading allows the existing crack to propagate through the new layer eventually leading to its faster deterioration. Paving fabrics installed at the interface of asphalt concrete layers mitigates the crack propagation thereby improves the service life of pavements. Fabrics made from natural fibers such as coir and jute satisfies the minimum mechanical strength requirements for paving application. Hence, this study focuses on the evaluation of natural paving fabric's potential through laboratory testing methods to create more sustainable pavements.
