    Abstract: La preparacion de una composicion de asfalto usando una composicion modificadora de asfalto que comprende al menos un miembro seleccionado del grupo que consiste de modificadores a base de caucho y modificadores a base de resina y un compuesto de fosforo permite que el modificador sea disuelto satisfactoriamente en el asfalto. Además, cuando la pavimentacion se conduce usando una composicion para pavimentar preparada con tal composicion de asfalto, la adhesion del asfalto a un agregado es alta, y el pavimento resultante tiene una mejoría notable en la resistencia a la formacion de surcos y resistencia al desgaste. Por lo tanto, tal pavimento tiene una vida de servicio prolongada.
