Pavement Recycling Systems Rapidmix Mobile Continuous Mixing Plant RCC CTB Port of Long Beach Middle Harbor Redevelopment Project



Featured DHE, Inc. project: Pavement Recycling Systems – RCC & CTB at Port of Long Beach Middle Harbor Redevelopment Project

DHE, Inc, recently supplied and commissioned a Rapidmix 400CW, fully weighed, mobile continuous mixing plant (pugmill) for Pavement Recycling Systems. The new Rapidmix is being utilised initially for the production of RCC (roller compacted concrete) for the Port of Long Beach Middle Harbor Redevelopment Project. The Rapidmix will also be involved in the production of RCC and various other materials for future projects across California and other Western US States.


Rapidmix 400CW Mobile Continuous Mixing Plant

The Rapidmix mobile continuous mixing plant is completely self-contained and  portable and capable of 400 tons per hour continuous production capacity. Powered by a Volvo tier 4 generator, no outside power is necessary. Hydraulic self-erect allows the entire plant to be erected and ready to produce within hours. By the end of the first day, we had the plant erected, calibrated, and mixing.


Rapidmix can handle a wide range of job required applications. From roller-compacted-concrete to cement-treated-base, the Rapidmix can switch effortlessly between its stored recipes with the touch of a button. Have a specialty material? The machine can be configured to fit your needs. This machine was designed for a unique material. Pavement Recycling Systems added the ability to supply a third-party bitumen pump for asphalt recycling.

Quality of Life

Quality of life for operators is a major priority for Rapid International. That’s why the Rapidmix has a clean out conveyor for the mixing chamber, hydraulic side doors for mixing chamber clean out, touch panel controls with remote laptop included. Allen Bradley PLC controls the plant through a user-friendly touch screen. Within two days DHE, Inc. had the entire crew running production through the plant, creating new mix recipes, and troubleshooting plant alarms.
