DEVELOPMENT OF A MANUALLY OPERATED DOWEL-BAR INSERTER
An investigation has established the beam stiffness of centrifugal force requirements for a manually operated dowel-bar inserter intended for constructing dowelled contraction joints in concrete paving slabs built by semi-manual methods. The trails showed that the prototype equipment can place dowel bars in a compacted slab quickly with an accuracy similar to the standards achieved on major road works. The use of an inserter should reduce the labor and materials costs of forming dowelled contraction joints by about 1 pound per metre length of joint and so lead to an overall cost saving on all but very small jobs.
