dc.description<p>Crack sealers are crucial for preserving concrete bridge decks and extending their service life. This paper presents a comprehensive national survey in the U.S., gathering responses from a total of 37 different agencies, along with literature studies on crack sealer practices in concrete bridge decks. The study covers various aspects, including available crack sealers, sealing triggers, approved product list and performance, resealing intervals, method selection, and surface preparation. Based on the study findings, epoxy, methyl methacrylate (MMA), and high-molecular-weight methacrylate (HMWM) are the most commonly used crack sealers, each offering distinct advantages. Sealing criteria are based on crack dimensions and deicing exposure. Resealing intervals vary due to sealant composition, deck age, and climate. Method selection considers deck attributes, temperature, and moisture. The study identifies gaps in consistently approved product lists and suggests future research areas, such as investigating the effects of entrapped chloride, conducting long-term performance testing, and correlating laboratory and field data. The study’s findings contribute to current practices, facilitating decision-making and providing guidance for targeted future research.</p>eng
