Dowel bars tend to be inserted at mid-slab depth and coated with a bond-breaking compound to forestall bonding on the PCC. Consequently, the dowels help transfer load but let adjacent slabs to grow and deal unbiased of one another. Figure three reveals standard dowel bar spots in a transverse development joint.
Fungsinya adalah untuk mencegah pergeseran lateral antarbagian beton dan meningkatkan kekuatan serta kestabilan sambungan horizontal.
Together with the dimensions, materials, and placement of dowel bars, You will also find other factors to contemplate when making use of dowel bars in concrete pavement building. These consist of the type of joint sealant to use, the tactic of putting in the dowel bars, and the kind of reinforcement to work with.

Mencegah Retak: Dowel membantu mencegah terjadinya retak pada sambungan beton dengan menahan gaya-gaya yang bekerja pada struktur, seperti beban bekerja dan gaya geser. Dengan demikian, dowel membantu menjaga kekuatan dan keawetan struktur beton.
Sebagai pengguna jalan, pasti Anda sering melintasi jalan beton semen. Jalan ini terdiri dari beberapa panel beton yang dicor terpisah-pisah kemudian disambungkan menjadi satu kesatuan.
Dowel bars are short metal bars that provide a mechanical link amongst slabs with out proscribing horizontal joint movement.
Tie bars are deformed rebars or connectors utilized for holding faces bar towel holder clip of rigid slabs in contact to take care of mixture interlock. Tie bars are usually not load transferring machine. For instance, tie bars are Employed in longitudinal joints in concrete pavement.
b) be capable of transfer shear into adjacent slabs on quality and so forth in which designers are comfy with that method.
Use the correct size and grade - The size and quality with the starter bars need to be selected according to the Dowel Bar load-bearing specifications in the construction plus the Qualities of the prevailing concrete.
There are many differing types of joint sealants offered, together with asphaltic sealants, polyurethane sealants, and silicone sealants. Every sort of Dowel Bar sealant has its have pros and cons, so it's important to choose the correct sealant for the specific undertaking.
For allowing actions, dowel bars are put across transverse joints of concrete pavement. They may be inserted at the center depth of your slab and are coated by using a bond-breaking substance for limiting bonding to your PCC.
