Scope: where and on what joints
- The order applies to all concrete paving works implemented by the DPWH.
- The order covers concrete paving implemented by Contract.
- The order covers concrete paving implemented by Administration.
- The order requires proper asphalt sealant application on all types of joint of the concrete pavement.
- The order identifies joint types as transverse contraction/weakened plane, construction joints, and longitudinal joints.
Mandatory standard: observe proper application
- Project implementing offices must strictly observe proper application of asphalt sealant on concrete pavement joints.
- Project implementing offices must use the appropriate penetration grade for the asphalt sealant.
- Project implementing offices must apply asphalt sealant in accordance with Subsection 311.3.17 (Sealing Joints) of the DPWH Standard Specifications.
- Project implementing offices must ensure correct asphalt sealant use because insufficient asphalt sealant affects structural integrity and imperviousness to water of the pavement and its underlying courses.
- Project implementing offices must ensure correct asphalt sealant use because excessive application affects riding surface smoothness and causes bumpiness and finishing issues.
Inspection and pre-opening requirements
- Project implementing offices must ensure the surface of newly completed concrete pavements is free from any excess asphalt sealant.
- Project implementing offices must ensure the surface of newly completed concrete pavements is free from concrete laitance.
- Project implementing offices must accomplish these cleanliness requirements prior to opening to traffic.
Implementation direction and compliance focus
- The order directs concerned project implementing offices to strictly observe the required sealant application requirements.
- The order emphasizes compliance with the specified joint-sealing standard under Subsection 311.3.17 (Sealing Joints).
- The order requires application control both in quantity (to avoid insufficient or excessive application) and in surface condition (to avoid excess sealant and concrete laitance).
Effectivity
- The order provides that it takes effect immediately upon adoption on 08 February 2011.
