A STATEMENT ON THE DESIGN AND USE OF ASPHALT STABILIZED BASE COURSES-KANSAS HIGHWAY COMMISSION

THE FLEXIBLE PAVEMENT DESIGN SYSTEM USED IN KANSAS WAS DEVELOPED ABOUT 1938 AND ITS USE ON CONSTRUCTION PROJECTS BEGAN ABOUT 1943. THE DESIGN THEORIES USED ARE BASED ON ORIGINAL BOUSSINESQ THEORIES, REFINED AND EXTENDED BY OTHER INVESTIGATORS AND ORIENTED FOR USE IN THE DESIGN OF FLEXIBLE PAVEMENTS. THE TRIAXIAL COMPRESSION TEST IS UTILIZED FOR THE PRODUCTION OF BASIC DATA ON THE STRUCTURAL PROPERTIES OF THE VARIOUS COMPONENTS IN THE PROPOSED PAVEMENT STRUCTURE BEGINNING WITH THE SOIL SUBGRADE AND EXTENDING UPWARD THROUGH EACH LAYER OF THE SYSTEM. IN APPLICATIN, THIS DESIGN SYSTEM IS USED TWICE: (1) TO ESTIMATE THE FLEXIBLE PAVEMENT STRUCTURE REQUIRED AT A SPECIFIC LOCATION AT THE TIME THE ORIGINAL SOIL SURVEY IS MADE, AND (2) WHEN THE GRADING HAS BEEN COMPLETED. IN THE FIRST CASE, THE DESIGN IS BASED ON THE PROPERTIES OF THE SOILS AT THE SITE OF THE PROJECT, AND, IN THE SECOND CASE, THE DESIGN IS REFINED BY USING DATA OBTAINED BY TESTING THE SOILS IN PLACE ON THE COMPLETED SUBGRADE. EACH PAVEMENT AND GRADING PROJECT IS ANALYZED IN THIS MANNER AND REPORTED IN WRITING FOR THE USE OF THE ROAD DESIGNER AND THE ADMINISTRATIVE OFFICERS OF THE DEPARTMENT. THE RESULTS OBTAINED MAY BE ALTERED BY ASSIGNING DIFFERENT VALUES TO THE VARIOUS FACTORS IN THE FORMULA; HOWEVER, THE SYSTEM AS USED IN KANSAS HAS BEEN SUBSTANTIATED PERIODICALLY BY CORRELATION STUDIES OF PAVEMENTS IN SERVICE. AFTER EACH STUDY THE COEFFICIENTS ARE ADJUSTED IN ACCORDANCE WITH SERVICE RECORDS.
