Joint Sealant For Concrete Pavement

Several state agencies have gained many years of experience with joint filling and with open unsealed unfilled joints in concrete pavements.

Joint sealant for concrete pavement.

Pavement engineers have recognized the need for concrete pavement joint sealants for many years. Sealants also reduce dowel bar corro sion potential by reducing entrance of de icing chemicals. Each product can be used to seal new or existing concrete and asphalt joints and both are formulated for use on highway airport parking structures and bridge joints where high movement occurs. The word sealant became more common and in essence defined the switch in expectations.

Dsb 800 is a low modulus high performance one part non sag silicone joint sealant. British standard institution specification for cold poured joint sealants for concrete pavements bs 5212. Its one component technology offers ease of use and cost effectiveness. About crafco pavement preservation maintenance.

Dsb 900 sl is an ultra low modulus high performance one part self leveling silicone joint sealant. Wisconsin was the first highway department to stop sealing joints and specify open joints 18. Clearly defining the impact of joint sealing through pavement perfor mance studies. Today nearly every agency building and maintaining concrete roadways or airports requires joint sealing.

The pourthane joint sealant line is designed for sealing concrete and metal joints in a variety of applications including sidewalks balconies pavement terraces warehouses factories civil structures plazas and pitch pans. 888 silicone joint sealant is ideal for use in concrete to concrete joints pcc that experience a high degree of movement such as transverse pavement expansion and contraction joints in highways airports and other pavements. It withstands extension of 100 percent and compression of 50 percent of original joint width and has excellent recovery. Using concrete joint sealant to seal concrete expansion joints and concrete contraction joints in concrete floors and concrete walls is an important part of maintaining the integrity of the concrete.

Crafco is the world s leading manufacturer in quantity and diversity of packaged pavement preservation products for asphalt and concrete such as hot applied crack sealants silicone joint sealants hot applied mastics and cold mix for pavement surface patching and repair. British standard institution guide to selection of constructional sealants bs 6213 1982. British standard institution code of practice of joints and jointing in building construction bs 6093 1981. Many engineers today think of sealant materials primarily for their ability to prevent water from passing through concrete pavement joints.

Sealant use dates back to the early 1900 s. Installing the proper kind of concrete joint sealant will help protect the structure from moisture damage caused by rain wind gravity capillary force and surface tension.
