Abstract
Se describe una composicion que comprende al menos una parte A y una parte B. La parte A comprende al menos un poliol y la parte B comprende al menos un isocianato. Al menos una parte adicional comprende al menos uno de lo siguiente: un mejorador de resistencia que tiene un punto de suavizacion de aproximadamente 48.8 degree C (120 degree F) a aproximadamente 204 degree C (400 degree F) ; un mejorador hidrofobico no reactivo; y/o un mejorador de absorcion de impacto. Estos mejoradores proporcionan, entre otros beneficios opcionales, resistencia de traccion mejorada. Adicionalmente, una masa puede prepararse por un metodo de combinacion de la parte A con la parte B y aplicando la mezcla a un vacio. Las composiciones pueden utilizarse tambien para reparar los defectos de superficie o para el reforzamiento de miembros estructurales tales como agujeros de clavos retirados despues de la remocion de clavos a partir de las traviesas de vias ferreas durante el mantenimiento o reparacion del terraplen.
