These machines include, among others, Computerized profilograph, Rolling thin film oven, Hydraulic Kneading Compactor, Shear testing system, and Axial testing system.

In 1989 Cox & Sons was selected by University of California at Berkeley to design and manufacture the prototype for the shear testing system for the federal Strategic Highway Research Program (SHRP). SHRP was initiated to develop standards for road construction in this country.   The original testing system is currently in use at the Richmond Field Station (UC Berkeley) and there are several of the enhanced shear testing systems with confining pressure in the field at this time.

Cox & Sons has built a reputation for manufacturing the highest quality equipment utilizing the finest materials and the latest technology.   We integrate all of these factors to provide top-of-the-line systems for a complete solution for the customer.
