RESEARCH PAYS OFF--NEW JERSEY DOT DEVELOPS IMPROVED PROCEDURE FOR ADJUSTING MANHOLES

A new procedure for adjusting manholes which involves the use of a bedding compound plus bolts to anchor the cast iron extension frames has been developed. The details are given of this procedure which was used in a project in which over 100 epoxy-bonded manhole extension rings were successfully placed on badly worn and cracked municipal and county manhole frames dating to 1913. Guidelines and specifications for the procedure and the materials for adjusting manholes and curb inlets with an epoxy bonding compound was developed and incorporated into standard specifications. This procedure has led to construction cost savings of $230 to $270 per inlet (total of approximately $200,000) on New Jersey Department of Transportation projects.
