dc.description.abstract	The use of scrap rubber in ballasted tracks has shown promising results in terms of vibration reduction, enhancement of damping ratio, and so on, but its use in slab tracks has not been explored yet.

The optimum content of rubber and PFA were obtained from static direct simple shear test. This optimum rubber and PFA dosage were then used to prepare triaxial specimens and tested cyclically to assess the performance of the treated and untreated soil.

The novel base material shows superior performance in terms of the reduced settlement, decreased excess pore water pressure and enhanced damping ratio.

Abstract:

The use of scrap rubber in ballasted tracks has shown promising results in terms of vibration reduction, enhancement of damping ratio, and so on, but its use in slab tracks has not been explored yet. The present study investigates the use of scrap rubber in the form of ground and granulated rubber mixed with soil and treated with Polyurethane Foam Adhesive (PFA). The optimum content of rubber and PFA were obtained from static direct simple shear test. This optimum rubber and PFA dosage were then used to prepare triaxial specimens and tested cyclically to assess the performance of the treated and untreated soil. A novel base layer for a slab track comprising soil, scrap rubber and PFA is proposed. The novel base material shows superior performance in terms of the reduced settlement, decreased excess pore water pressure and enhanced damping ratio.
