BRIDGE DECK PERFORMANCE IN VIRGINIA
A RESURVEY WAS CONDUCTED IN 1970 TO DETERMINE THE CHANGE IN PERFORMANCE CHARACTERISTICS OF VIRGINIA BRIDGE DECKS WHICH WERE INSPECTED IN 1961 DURING A COOPERATIVE SURVEY BY THE PORTLAND CEMENT ASSOCIATION AND THE BUREAU OF PUBLIC ROADS. AS EXPECTED, DETERIORATION WAS OBSERVED TO INCREASE IN FREQUENCY AND SEVERITY. THE RELATIVE ORDER OF THE THREE MOST PREVALENT DEFECTS, I.E., SCALING, CRACKING, AND POPOUTS, REMAINED THE SAME. IN 1970 SURFACE SPALLING WAS THE FOURTH MOST PREVALENT, WHEREAS IN 1961 IT WAS OF THE SAME ORDER AS RUSTING AND JOINT SPALLING. IN DATA ANALYSIS FROM THE 1970 SURVEY, A PRIMARY CONCERN WAS TO DETERMINE AND REPORT THE INCREASE OF CONCRETE DETERIORATION. THIS IS DONE THROUGH THE USE OF TABLES AND FIGURES FOR COMPARATIVE PURPOSES. RESULTS OF A SURVEY BY THE VIRGINIA HIGHWAY RESEARCH COUNCIL IN THE INTERVENING YEARS ARE ALSO DISCUSSED.
