EVALUATION OF BRIDGE PATCHING MATERIALS (POLYMER CONCRETE) OPERATIONAL PLANNING

Preparatory operational procedures are outlined which involve laboratory control and field personnel organization. Details are given of the budget and the rental of the laboratory trailer. The basic trailer specifications are set forth and the special chemicals used are listed. Step by step operations are described of four sites selected for field testing of various types and uses of the polymers. The first project involved patching a hole (2' x 2') full depth of the reinforced concrete deck of the subject bridge with polymer concrete and to impregnate the existing concrete around the hole with polymer. A 11-step procedure is outlined for the (2nd project) patching of a section of a bay along the curbline by removing the deteriorated concrete, full depth, from the center of beam no. 2 to the center of beam no. 3, using both polyester styrene and MMA (promoted chemically by heat). Similar projects are described involving patching of shallow surface holes, and the patching of a section bridge deck.
