THE JOB
The pavement of a rural road outside of Williamsburg, Virginia collapsed suddenly. The pavement was adjacent to a golf cart tunnel, but there was nothing apparently wrong with the cart tunnel. VDOT closed the road to perform exploratory excavation. The exploratory excavation revealed a partially-collapsed RCP culvert pipe running adjacent to the golf cart tunnel. This required emergency pipe abandonment.
THE CHALLENGE
CJGeo had to mobilize with very little notice. The proposed grout had to have the ability to flow through the unknown obstructions in the collapsed RCP, and also out into any voids outside of the collapsed pipe.
THE SOLUTION
CJGeo proposed 30lb/cuft CJFill-Ultra Lightweight cellular grout due to its highly flowable characteristics. Cellular concrete is excellent for ensuring complete fills of collapsed or compromised pipes.
CJGeo mobilized to the site within one day and completed the emergency pipe abandonment in less than two hours. The road was opened back up to traffic immediately afterward.
The 30lb/cuft CJFill-Ultra Lightweight cellular grout that CJGeo placed on this project has an average strength of around 150psi at 28 days. However, it will accept foot traffic and equipment traffic within 12 hours. In this case, the collapsed pavement had already been reconstructed after the compromised pipe was identified.
