PAVING FORMS (IF USED) Are the forms: metal, not less than 3 meters in length, equipped with both pin locks and joint locks, within 2 millimeters along the length of its upper edge, within 7.5 millimeters along the length of its front face, and in sufficient supply. Is the height of form face at least the edge thickness. of proposed <strong>pavement</strong>, the base width equal to or greater than the height, and are three steel pins being used to secure each section? Are the forms being set on a hard and true grade, built up in 12.5 millimeters maximum lifts of granular material in low areas (without using wooden shims) and oiled prior to the placing of concrete? When wooden forms are allowed, are they full depth, smooth, free of warp, not less than 50 millimeters thick when used on tangent, and securely fastened to line and grade? Are curved form of metal or wood being used on curves of 30 meters radius or less? 3. FORM ALIGNMENT Is the contractor checking the forms for line and grade and making necessary adjustments prior to concrete placement? Is the surface of the subbase being tested for crown and elevation by means of a template? 3.10.33
