UTAH'S EVALUATION OF THE MUMETER

UTAH'S MUMETER WAS PURCHASED IN JULY 1969. WHEN PURCHASED, THE MUMETER WAS NOT EQUIPPED WITH A WATER SPRAYING SYSTEM OR A SYSTEM TO CONTROL THE POSITION OF THE TEST WHEELS. BOTH THESE SYSTEMS WERE INSTALLED BY THE DEPARTMENT MAINTENANCE SHOPS SOON AFTER THE MUMETER WAS PURCHASED. AFTER SEVERAL MONTHS OF CHECKING OUT THE RELIABILITY AND REPEATABILITY OF THE MUMETER, CORRELATION TESTS WITH COLORADO HIGHWAYS DEPARTMENT'S ASTM E-274 SKID TRAILER WERE RUN. THE CORRELATION COEFFICIENT OBTAINED WAS 0.981. CORRELATION TESTS WERE ALSO RUN WITH ARIZONA HIGHWAY DEPARTMENT'S MUMETER. THIS MUMETER WAS MODIFIED SIMILAR TO UTAH'S. THE CORRELATION COEFFICIENT WAS 0.982. BOTH OF THESE CORRELATIONS WERE VERY GOOD. THE DEPARTMENTS RESEARCH SECTION IS PRESENTLY INVOLVED IN A RESEARCH STUDY ENTITLED, "A SYSTEM FOR ROADWAY DESIGN." FOR THIS STUDY THE MUMETER IS BEING USED STATEWIDE TO GATHER SKID DATA ON APPROXIMATELY 4000 MILES OF HIGHWAY. THE MAINTENANCE COSTS FOR THE MUMETER HAS BEEN COMPARATIVELY SMALL AND ITS OVERALL PERFORMANCE HAS BEEN EXCELLENT.
