COLORADO'S FLEXIBLE PAVEMENT DESIGN METHOD

THE COLORADO DESIGN METHOD EVALUATES: (1) THE CAPABILITIES OF THE NORMAL BASEMENT SOILS TO SUSTAIN LOADS WHEN THEY ARE IN DIFFERENT DEGREES OF SATURATION, (2) THE ANTICIPATED TRAFFIC VOLUMES FOR A PERIOD OF 20 YEARS, AND (3) THE DAMAGE TO THE PAVEMENT STRUCTURE THAT IS PROBABLE FROM THE FROST POTENTIAL OF THE SOILS OVER WHICH THE PAVEMENT IS TO BE PLACED. SOIL STABILIZATION IS DETERMINED BY A STABILOMETER EQUIPMENT DEVELOPED BY HVEEM. THE TOTAL THICKNESS OF THE PAVEMENT STRUCTURE IS DETERMINED FROM THE DESIGN CHART. THIS IS ASSUMED TO BE THE GRAVEL EQUIVALENT OF THE CALIFORNIA DESIGN CHART. IT IS THEN USED IN COMBINATION WITH THE CALIFORNIA DESIGN CHART TO DEVELOP THE BALANCE OF THE PAVEMENT STRUCTURE. THE DESIGN CURVE FOR A PROJECT IS SELECTED USING THE FOLLOWING DATA: (1) SOILS INFORMATION FROM THE CENTRAL LABORATORY, WHICH INCLUDES FROST POTENTIAL ESTABLISHED FROM THE SOIL SAMPLES, (2) TRAFFIC DATA SUPPLIED BY THE PLANNING AND RESEARCH DIVISION FROM THEIR TRAFFIC SURVEYS, AND (3) FROST PENETRATIONS FROM FIELD SURVEYS. PERFORMANCE DATA FROM 8 YEARS OF EXPERIENCE INDICATES SATISFACTION SUFFICIENCY RATINGS RESURFACING AND RECONSTRUCTION PROJECTS ARE HANDLED IN A MANNER IDENTICAL TO NEW CONSTRUCTION.
