418Asphalt Pavement Joint Adhesive

418-1 Description

This work shall consist of furnishing and installing joint adhesive in accordance with the contract documents and as directed by the Engineer.

418-2 Materials

Use a product which appears on the NYSDOT Approved List under ASPHALT PAVEMENT JOINT ADHESIVE (705-19) meeting the requirements of §705-19.

418-3 Construction Details

418-3.01 General. Furnish all equipment that is necessary to clean the construction joint and to apply the

joint adhesive. Use equipment meeting the description and/or performance requirements described herein and approved by the Engineer. Apply the joint adhesive to the construction joints.

418-3.02 Joint Preparation. Prepare longitudinal and transverse construction joints as discussed below

and place adjacent asphalt pavement on the same day that the joint adhesive is applied. Use a high pressure air lance to thoroughly clean the joint surface of dust, dirt, foreign material, sand and any other extraneous materials immediately prior to applying the joint adhesive. Install suitable traps or devices on the compressed air equipment to prevent moisture and oil from contaminating the joint surfaces. Maintain these devices and see that they are functioning properly. Protect the public from potentially objectionable and/or hazardous airborne debris.

418-3.03 Joint Adhesive. Heat and melt the joint adhesive in a melter constructed either as a double

boiler filled with a heat-transfer medium between the inner and outer shells, or with internal tubes or coils carrying joint adhesive through a heated oil bath and into a heated double wall hopper. The melter will be equipped with separate thermometers to indicate the temperature of the heat transfer medium and the joint adhesive material, positive temperature controls, and with a mechanical agitator or a recirculation pump to assure a homogeneous blend of the joint adhesive. Check the discharge temperature of the joint adhesive with a non-contact infrared thermometer or other suitable thermometer. Discharge the joint adhesive at the manufacturer's recommended application temperature and maintain the joint adhesive at ± 10°F of the application temperature indicated on the material packaging. Applying joint adhesive is not permitted if the melter and discharge temperatures do not meet the requirements described above. Equip the discharge hose with a thermostatically controlled heating apparatus or insulate it to maintain the proper joint adhesive application temperature. Holster the discharge hose to the melter if it is not thermostatically heat controlled. Circulate the joint adhesive from the discharge hose and the melter to maintain the proper joint adhesive application temperature. Do not use joint adhesive material that has been heated beyond the safe heating temperature. If the manufacturer's recommendations allow the joint adhesive to be reheated or heated in excess of six hours, recharge the melter with fresh material amounting to at least 20 percent of the volume of the material remaining in the melter.

418-3.04 Application. Apply the joint adhesive when surface temperature is 40°F and rising. Use an

applicator wand fitted with a sealing shoe to strike-off the adhesive. Strike-off the joint adhesive to provide a 1/4 inch to 3/8 inch thick band. The finished bands are to be approved by the Engineer.
