That is why PMI created Central Mix REAS (Rubberized Emulsion Aggregate Slurry). A high quality surface treatment that will prolong your road for over 5 years with an environmentally friendly material. Central Mix REAS is different from other slurries in that it is made at a central mix plant where all aspects of mixing can be controlled. With rigorous testing PMI can produce a long lasting and consistent material. We are so confident in our material that we are the only company to offer a 5 year warranty on our material. With over 30 years of experience as pavement preservation specialist PMI has the most experienced crews applying Central Mix REAS.
