Micro surfacing with latex modified emulsion (FHWA-OK-86-7) 2416
Abstract
This is the final report for the use of emulsified asphalt
in a relatively new process called "Ralumac Micro Surfacing".
This process was developed in Germany and was first used in the
United States in late 1980. In 1982, personnel from the
Oklahoma Department of Transportation (ODOT) Observed projects
in another state and proposed a project in Oklahoma.
The Ralumac process incorporates natural latex rubber with
the aspha;tt emulsion. It is mixed with aggregate and other
additives in a traveling pug mill similar to but larger than
that of a regular slurry machine.
The construction phase of this demonstration project was
completed in June, 1983.
The evaluation of data presented shows that the service
life of the test area has been enhanced. It is recommended
the Ralumac process be approved for routine use as a restoration
item for flexible pavements to fill surface ruts and cracks,
seal the surface, and restore skid resistance.
