Santa Anita is looking into the possibility of removing its dirt surface, where the majority of the track's 36 horse deaths since December have occurred, and going back to a synthetic surface.

In 2007, Santa Anita installed a mixture of silica sand, synthetic fibers, elastic fiber and granulated rubber with a wax coating after the California Horse Racing Board mandated the change for ...

A few of the rubber granules used as infill on the UCLA intramural field are shown across a fingertip. ... Manufacturers introduced a gentler surface using crumb rubber in the 1990s.

Certain waste materials, such as granulated rubber and wood chip, can be used in quantities up to 1,000 tonnes for horse maneges under a U8 waste exemption registration.

A $400,000 gift, plus a $200,000 challenge gift, from the Martin D. and Mary J. Walker Charitable Foundation will help fund the project.
