SECTION 409 — SAWING AND SEALING TRANSVERSE JOINTS IN ASPHALT CONCRETE PAVEMENTS OVER RIGID BASE — SAWING AND SEALING TRANSVERSE JOINTS IN ASPHALT CONCRETE PAVEMENTS OVER RIGID BASE
409.01 Description.
This work includes making a saw cut transversely across the finished asphalt surface pavement and filling cut with a hot poured asphalt rubber compound.
409.02 Materials.
Use poured joint seal material that is a hot poured asphalt rubber compound conforming to AASHTO M173 and approved by the Engineer.
409.03 Construction Methods.
Operation.
a.General. Make the saw cut directly over the existing underpavement of the transverse joints. Mark the existing joints to ensure the correct location.
b.S awing Joints . Construct the joints no sooner than 30 days after the surface course has been applied. Make the joint saw cut with a power -driven saw. Ensure that the cuts are ⅜-in. wide by ¾-in. deep. Make the saw cuts with an abrasive blade and saw dry. Extend the completed cuts in a straight line transversely across the pavement equal to the extension of the existing underpavement’s transverse joints. Reference each joint to be sawed.
c.Cleaning and Sealing Joints. Clean and seal the sawed joints immediately after the saw cut has been made. Do not allow traffic to knead together or damage the sawed joint. Ensure that each joint is dry before placement of the sealing compound. The manufacturer shall provide the melting temperature of the sealer, which must not be exceeded by more than 10°F. Ensure that all cracks are filled to refusal to eliminate all voids or entrapped air. Ensure that the hot seal fills the joint so that, after cooling, the level of the sealer will be flush with the pavement surface. Elevate any depressions in the seal to the specified limit by adding hot seal. Remove all excess or spilled sealer from the pavement by effective methods and discard.
409.04 Method of Measurement.
Sawing and Sealing Transverse Joints in Asphalt Concrete Pavement will be measured by the number of linear feet of sealed joints installed.
