RESPONSE OF CONCRETE HIGHWAY PAVEMENTS WITH ECONOCRETE BASES. FINAL REPORT

Two computer programs for stress and deflection analysis of concrete highway pavements, FEACONS for plate bending analysis considering a liquid subgrade, thermal curling and joint stiffness, and INPLANE for analysis under in-plane shrinkage, temperature and joint effects, were modified to handle skewed transverse joints. A series of calculations using FEACONS, under wheel loading and temperature, were performed to study the effect of subgrade stiffness levels and joint stiffness levels on the distribution of stresses in the pavement. Results were presented as profiles of principal stress and deflection magnitudes. A number of laboratory pilot tests were performed on plain unreinforced beams to study the fatigue resistance in flexure of Florida concrete.
