This directory lists 15 hot mix asphalt plant locations in the Inland Empire, across 2 counties, with the most around Corona, Fontana, Cabazon, Desert Hot Springs. Most come from federal air-permit registrations, which record that a plant is permitted rather than that it is operating or selling today, so treat the count as a starting list. 4 locations have had phone, hours and sales policy checked with the operator.

Some do and some do not. Many plants are owned by a paving contractor or a materials group and run mainly to supply that company's own crews, and whether a plant will load an outside contractor's trucks is not in any public record. Call the plant, say what mix and tonnage you need, and ask whether they sell to outside contractors and on what terms before you plan around it.

There is no fixed limit: it depends on the weather, the load size, tarping and how fast the crew places the mix. As a planning figure most contractors treat about an hour of drive time as comfortable and manage the risk carefully beyond about 90 minutes, and your specification and supplier are the authority. Every drive time on this site is Google's, by road with typical traffic — allow more at rush hour. A job near a county line is often closer to a plant in the next county than to any in its own, which is why this page lists the Inland Empire as one area.

Caltrans certifies hot mix plants for state work through the MPQP and publishes a list of active plants each month, as a PDF and a spreadsheet. Approval expires, so check the current month's list rather than an old copy. Caltrans's program is the Material Plant Quality Program (MPQP). Private work does not normally require approval unless the contract calls for it.
