Proper jointing is based on controlling cracks that occur from the natural actions of the concrete pavement. Joints are placed in the pavement to control the crack location and pattern. Observing the slab behavior of unjointed plain pavements in service for many years can illustrate how joints are used to control cracking.
5 Ways to Fill Paver Joints - Western Interlock
2023年10月11日 · This article will explore five distinctive ways to fill your paver joints, each offering benefits and considerations. Whether you’re aiming for a classic, low-maintenance finish or a modern, durable solution, these options will help you make an informed choice that aligns with the specific needs of your project.
Construction joints are used between separate concrete placements, typically along placement lane edges. Butt joints are recommended for most parking lots or low volume streets where load transfer needs are minimal. Doweled joints are recommended for high truck traffic roadways or driveways where load transfer enhancement is needed.

Fill joints with sand or jointing material. Compact and seal the surface. Our team ensures each step is executed with precision, guaranteeing a durable and visually ...
Joints - ACPA
There are three basic joint types used in concrete pavement: contraction, construction and isolation. Specific design requirements for each type depend upon the joint's orientation to the direction of the roadway (transverse or longitudinal).
Joints in Concrete Pavements: Transverse & Longitudinal joints
2023年9月13日 · Joints in concrete pavements are provided in a pavement slab in order to allow for movement caused by changes in moisture content and slab temperature. Transverse joints across the pavement at right angles to its centreline permit the release of shrinkage and temperature stresses.
Step 1: Draw pavement edges and back-of-curb lines. Draw locations of all manholes, drainage inlets, and valve covers so that joints can intersect. Step 2: Draw all lane lines on the legs and in the circular portion, accounting for roundabout type. Make sure no distance is greater than the recommended lane width (typ.15ft -16ft.)
Application Guide for Interlocking Concrete Pavements
Concrete pavers are then placed on a layer of bedding sand (1 in. or 25 mm thick), compacted, sand swept into the joints, and the units compacted again. When compacted, the pavers interlock, transferring vertical loads from vehicles to surrounding …
Proper jointing aids in preventing random cracking of pavements that can occur when c o n c r ete changes volume with changes in moisture and tempera- ture. Causes of cracking. One of the principal causes of c r acking of pavements is dry i n g s h ri n k a g e.
