Abstract
A recycled-aerogel composite includes a multiplicity of swelled crumb rubber particles and a filler. Each swelled crumb rubber particle includes a crumb rubber particle defining pores, and oil distributed throughout the pores. The filler includes a multiplicity of fibers, aerogel material, or both. A modified asphalt binder includes asphalt binder and the recycled-aerogel composite. An asphalt pavement includes the modified asphalt binder and aggregate. Methods of making the modified asphalt binder and a recycled-aerogel composite are described.

A method of making a recycled-aerogel composite, the method comprising:
- contacting crumb rubber particles with oil to yield swelled crumb rubber particles;
- combining the swelled crumb rubber particles with an encapsulator to yield a mixture;
- and
- combining the mixture with aerogel material to yield the recycled-aerogel composite.
A method of making a recycled-aerogel composite, the method comprising:
- contacting crumb rubber particles with oil to yield swelled crumb rubber particles;
- combining the swelled crumb rubber particles and aerogel material to yield a mixture;
- combining an encapsulator with the mixture, wherein the encapsulator at least partially encapsulates each of the swelled crumb rubber particles and the aerogel material.
