Headings are also includedbearing on other features of constructionwhich are most frequently neglected inpavement work. The subject will be considered underheadings as follows: Pavement SectionThe methods of design here outlinedare intended to provide a pavement ableto sustain the traffic of cities havingfrom five to fifty thousand inhabitants,and for successful use on country high-ways. The design includes the determi-nation of the most economical shape ofcross-section and the proper thicknessrequired to resist the forces tending torupture it. The forces tending to crack a concretepavement longitudinally are: (1) Freezing and thawing. The action of frost in the ground atthe edges of a concrete pavement willcreate a force sufficient to raise andlower the sides of the pavement. slab, and unless theslab is of properthickness and stren
