Joint Design - Pavement InteractiveJoint width and depth are dependent on two separate things. First, joint depth should be between 1/4 and 1/3 of the total slab depth to ensure crack formation at the joint. Joints shallower than this may not sufficiently weaken the vertical plane. Second, joint width is selected to provide an adequate joint sealant reservoir.

TECHBRIEF Resealing Concrete Pavement JointsResealing concrete pavement joints is a common pavement maintenance activity. Joint sealants reduce the amount of water entering the pave-ment structure and prevent incompressible materials from filling the joints. Water entering the pavement structure can lead to pumping, faulting, base and subbase erosion, and loss of support.
CONCRETE PAVEMENT GUIDE - CaltransConcrete pavement joints can be sealed using liquid sealants or preformed compression joint seal materials. Liquid sealants are either hot-applied asphalt rubber or coldapplied silicone materials used - with backer rods. Preformed compression joint seals are elastomeric polychloroprene materials placed with lubricant adhesive.

AASHTO - NTPEP - PCC Joint Sealants/HMA Crack SealersJoint Sealants are commonly used to protect and seal Portland Cement Concrete (PCC) pavement joints. Under this NTPEP evaluation program, both hot-poured and cold-applied joint sealants materials are field tested for three years and laboratory tested according to a variety of ASTM specified test methods.
Are Pavement Joint Sealants Always Necessary?| Concrete ...The pavements with unsealed joints performed better than the pavements with sealed joints. The pavements with shorter joint spacings performed better than the pavements with longer joint spacings. Some sealants can keep joints effectively sealed for ten years, if the joints are properly designed. Joint sealing costs are not justified.
Evaluation of Joint Sealants of Concrete Pavementsestimation of the service life of a sealant in concrete pavement joints. Material and pavement engineers can use this procedure for design and maintenance purposes. This report also proposes a specification and a test protocol for joint sealant materials, which incorporate performance prediction procedure. The
