CONDITION EVALUATION OF CONCRETE BRIDGES RELATIVE TO REINFORCEMENT CORROSION. VOLUME 5: METHODS FOR EVALUATING THE EFFECTIVENESS OF PENETRATING SEALERS. FINAL REPORT

An electrical resistance method and a surface absorption method for the evaluation of penetrating sealers for portland cement concrete for bridge structures were tested in the laboratory and in the field. Both methods are nondestructive, rapid, and can be used on horizontal and vetical surfaces. Laboratory results are comaparable to the AASHTO T259 or NCHRP 244 Series II tests. Field results were generally successful, but hot or cold temperature made it difficult to perform the tests. Further information about evaluating the field performance of penetrating sealants was obtained by surveying the highway agencies in the United States and in Canada.
