PARTIAL POLYMER IMPREGNATION OF CENTER POINT ROAD BRIDGE
The application of polymer-impregnated concrete to an actual bridge deck is described. A method of determining the need for cleaning the surface is presented which consists of performing monomer penetration tests on sandblasted and non-sanblasted cores. Teh procedures used for the polymer impregnation of the Center Point Road bridge are described in detail. The deck was dried and cooled overnight. Monomer was applied at different rates on the test area and kept in place by means of a shallow sand cover. After the monomer was permitted to cool for several hours, the concrete was heated to polymerize the monomer. No bonded sand or discoloration was evident on the surface following the impregnation process. Cores revealed that polymer depth ranged from 1 in. (2.5 cm) to 1.9 in. (4.8 cm), with the greatest depth occurring in the area where the largest amount of monomer was used. Costs of polymer impregnation based on bids received by the State Department of Highways and Public Transportation ranged from $5/sq yd ($6.00/sq m) to $15.00/sq yd ($18.00/sq m) for the largest bridge which had an area of 5396 sq yd (4512 sq m). /Author/
