Superseded: Technical Advisory T 5040.30 Concrete Pavement Joints
(2) Sealant behavior has a significant influence on joint performance. High-type sealant materials, such as silicone and preformed compression seals, are recommended for sealing all contraction, longitudinal, and construction joints. While these materials are more expensive, they provide a better seal and a longer service life.

PCC Joint Construction – Pavement Interactive
Joint sealants used today are typically one of three types (ACPA, 2001a [2] ): Hot-pour liquid sealants. These sealants are heated up to decrease their viscosity and then poured. Joints are ready for traffic as soon as the sealant has cooled. About 25 percent of roadway agencies use hot-pour sealants in transverse contraction joints.
12 Questions to Concrete Pavement Joints: Answers One By One
The recommended distance within expansion joints is between 10 feet or more. It should be set at least this near to assure that the concrete slabs do not crack or split into two. However, this distance can get even lesser than 10 feet; it all depends, if you are working on a small one. Concrete expansion joints can be set at any particular ...
Joint Sealing - ACPA Wiki
Joint sealing practices vary from location-to-location, but preliminary evidence suggests that while it might be acceptable to leave joints in high-speed highway pavements unsealed, joints in urban environments that service low-speed traffic should be sealed.
Concrete Construction, Joint Filler, and Sealer Material
The purpose of the joint sealing compound is to seal the joint against the entry of water and grit while not affecting the road's running surface. 1. Bitumen-rubber mixture 2. A compound of oxidized bitumen fluxes. 1. The floor's free horizontal movement is limited by its vertical movement. 2. Load transfer at its best. 3. Edge security 4.
Joint and Crack Sealing of Portland Cement Concrete Pavements
Inspect joints prior to sealing by rubbing your finger along the joint walls to ensure that no contaminants (dust, dried saw residue, dirt, moisture, or oil) are on the joint walls. The "wipe test" may also be performed (ACPA 2018). If dust or other contaminants are present, reclean joints to a satisfactory condition. Inspect joints for ...

TECHNICAL BULLETIN CP-18 SEALANTS VS. JOINT FILLERS - Euclid Chemical
filled with a semi-rigid joint filler; the only proper use of a sealant in an industrial floor is to fill joints not subject to traffic such as isolation joints at walls or columns and under racks. Epoxy and polyurea semi-rigid joint fillers restore continuity to a concrete floor that was disrupted by cutting joints into the surface.
Sealants In Concrete Pavements, Roads, Highways & Building Construction
Joint sealed at 21.5mm Total Movement = 4 mm The sealant has been subjected to 4mm extension on an initial sealed width of 17.5mm,therefore the % movement is calculated as 4 X 100 = 22.8% 17.5 Thus the sealant is operating within its rated MAF. Joint Depth Considerations
CONCRETE PAVEMENT REHABILITATION - Minnesota Department of Transportation
The term joint sealing is generic for sealing joints and cracks. These repairs include sawing and cleaning the concrete joint or crack face to provide a proper surface and shape factor to ensure adhesion of the sealer. Joints wider than 25 mm (1in.) may increase tire slapping. See Figures A and B 5-694.912 for examples of
Performance-Based Evaluation of Joint Sealants for Concrete Pavements
high percentage of failures in highway and airport concrete pavements occur at or near the joints. The primary cause of the premature failure of jointed PCC pavements is improper joint sealing and joint maintenance (Jackson, 1988). Failure in a rigid pavement joint may occur due to joint creeping, joint seal loss, bond (adhesion) or cohesion ...
