THERMAL EXPANSION AND CONTRACTION OF CONCRETE PAVEMENT IN UTAH
Investigation into the advisability of continuing the expansion-contraction control system on concrete pavements was undertaken to determine if this system is satisfactory in alleviating damage caused by expansion and contraction through temperature, moisture and internal chemical changes, varying conditions of loading and support and the shrinkage of concrete with age. The results of this research show that there was no uncontrolled cracking and no excessive joint movement or slab creeping. The expansion - contraction control system as specified for rigid pavement in Utah has proved to give satisfactory performance and should be retained. /FHWA/
