1001. 3(k) 1001. 3(k) D o not overlap sawed grooves or leave more than 1 inch of the surface without sawed grooves between passes or where a single pass of the grooving machine cannot be made. Remove and collect debris and slurry resulting from the grooving operations concurrently with the grooving operations. Surfaces are to be immediately left in a washed and clean condition, free from slurry and debris . Do not open to traffic until mechanical texturing is complete.
6.f.1 Test Area. Do not begin production grooving operations until the test area is accepted.
• Transverse Sawed Grooves. Perform a test pass of the grooving equipment. The test area is the width of a single pass of production grooving equipment by a length of one lane width. Check groove widths, depths and spacing to ensure conformance to requirements specified in
• Longitudinal Sawed Grooves. Perform a test pass of the grooving equipment. The test area is the width of a single pass of production grooving equipment by a length of ten feet longitudinally in one lane. Check groove widths, depths and spacing to ensure conformance to requirements specified in Section 1001.3(k)6.f. 3. 6.f.2 Mechanical Texturing with Transverse Sawed Grooves. Texture the deck surface with transvers e sawed grooves with the following characteristics :
• Perpendicular with centerline
• Rectangular in shape
• 1/8 inch (± 1/32 inch) in width
• 1/8 inch to 3/16 inch in depth
• Random groove pattern of 1.5 inches, 1.75 inches and 2 inches nominal center -to-center sawed groove spacing
6.f.3 Mechanical Texturing with Longitudinal Sawed Grooves. Texture the deck surface with longitudinal sawed grooves with the following characteristics:
• Parallel with centerline
• Rectangular in shape for straight bridge decks, sawed along the curve for curved bridge decks
• 1/8 inch (± 1/32 inch) in width
• 1/8 inch to 3/16 inch in depth
• 3/4 inch nominal center -to-center sawed groove spacing
progress uniformly from the spring line to the crown.
joints formed in the sidewalls as indicated. Form horizontal construction joints to provide keys, as shown on the Standard Drawings. When the concrete has reached the top of the sidewall, stop the concrete operation for 2 hours to allow for settlement of the wall concrete before placing the top slab.
