In developing countries such as Indonesia, the use of the road pavement recycling process has not been utilized continuously and maximally. The use of the Recycle Asphalt Pavement (RAP) technique has influenced the results for the fatigue test. Various ways to add other materials to the RAP have increased mixture rigidity, rutting resistance, but there are also impacts on crack resistance. Rejuvenation materials are often needed to be more flexible in how they are used. The rejuvenated properties of asphalt can be restored as required in the specifications. Ideally, rejuvenation should also have environmentally friendly properties, and it is better if the product is made from recycled materials. This study aims to increase the use of RAP by taking into account the increase in the value of road surface slip resistance due to an increase in road surface temperature. This recycling process uses a layer of the old road surface that is rejuvenated by the asphalt content by adding used oil and used tire powder in Nano size. Skid Resistance Test using the British Pendulum Tester with changes in temperature from 27 °C to 45 °C at 5 °C intervals have shown an increase in the mixture to high temperatures on the road surface. The addition of 1.25% Nano Crumb Rubber (NCR) to the optimal bitumen content has shown better performance than recycling without NCR.
