Kentucky Transportation Center Research Report
Due to the increasing use of deicing chemicals and the subsequent intrusion of chlorides into bridge decks, it is necessary to expand the use of available protective measures, including waterproofing materials. Waterproofing options that fall into three categories; 1) membranes (liquid and sheet systems), 2) friction polymers (laminates), and 3) polymer asphalts. This study assessed the waterproofing characteristics of these products. Prior to this study, no common test had been established to compare the performance of waterproofing products. A test method was developed that closely follows ASTM D5084, “Standard Test Methods for Measurement of Hydraulic Conductivity of Saturated Porous Materials …

The objective of this report is to determine the most effective method for bridge deck overlay construction and repair by assessing current practices; examining new products and technologies; and reviewing NCHRP (National Cooperative Highway Research Program) guidelines, state standard specifications, ASCE (American Society of Civil Engineers) infrastructure ratings, and original bridge core chloride penetration data. Based on the review, this report offers the following conclusions. Latex modified concrete (LMC) overlays perform well, provide a long service life, and are the most commonly used method of bridge deck rehabilitation. Ohio considers microsilica concrete (MSC) overlays as state of the art due …
