Reconstruction of the expansion joint system of existing concrete bridge decks.
“Correct implementation of expansion joint systems is one of the most important details in the construction of bridge decks, requiring great care in design, performance, and during various stages of implementation. Failure to pay attention to the construction, installation, and timely maintenance of expansion joint systems can cause significant and sometimes irreparable damage to the bridge structure. Moreover, inaccuracy in the execution of expansion joint systems can disrupt smooth traffic flow. Therefore, it is crucial to pay attention to the special characteristics of the system when rehabilitating expansion joints. This paper presents a method for rehabilitating expansion joint systems up to 10 centimeters (small S-EXJ expansion joints) for the roadway in reinforced concrete deck bridges, based on domestically produced rubber expansion joints. In this method, unlike current conventional methods, the asphalt pavement of the bridge deck is installed before the expansion joint system is set in place. Therefore, the proposed method, with particular consideration for the need for smooth movement and maintenance-related aspects of bridges, including water-tightness, is recommended. Efforts have been made to explain the details of the implementation process, ensuring that the proposed system, after full installation of the pavement, allows for maximum compatibility with longitudinal and transverse profiles.”
Types of Rubbers, Advantages, Applications, and How to Manufacture Rubber from Them
The correct execution of expansion joint systems is one of the most important details in the construction of a bridge deck, requiring careful attention in its design, performance, and various stages of implementation. Failure to properly construct, install, and maintain the expansion joint systems in a timely manner can cause serious and sometimes irreparable damage to the bridge structure. Additionally, a lack of precision in the installation of these systems can disrupt the smooth flow of traffic. Therefore, it is essential to pay special attention to the specific characteristics of the expansion joint systems when restoring them.
This article presents a method for the rehabilitation of expansion joint systems up to 10 centimeters (small S-EXJ expansion joints) for vehicular pathways on bridges with reinforced concrete decks, based on locally produced rubber expansion joints. In contrast to current common methods, this approach involves installing the asphalt deck before the expansion joint system is applied. Therefore, the proposed method places special emphasis on ensuring smooth traffic flow and considerations for bridge maintenance, including water-tightness. The article aims to explain the various stages of the work in detail, ensuring that after the completion of the asphalt layer, maximum alignment with longitudinal and transverse profiles is achievable.
Structure and Function of Resins Used in the Rubber Industry
The proper execution of expansion joint systems is one of the most critical details in the construction of a bridge deck, requiring careful attention to design, performance, and all stages of implementation. Failure to properly construct, install, and maintain the expansion joint systems on time can lead to serious, sometimes irreparable damage to the bridge structure. Additionally, a lack of precision in the installation of these systems can disrupt smooth traffic flow. Therefore, it is crucial to pay special attention to the unique characteristics of expansion joint systems when restoring them.
This article presents a method for the rehabilitation of expansion joint systems up to 10 centimeters (small S-EXJ expansion joints) for vehicular pathways on bridges with reinforced concrete decks, based on locally produced rubber expansion joints. In contrast to current common methods, the asphalt paving of the bridge deck is applied before the expansion joint system is installed. Therefore, the proposed method places particular emphasis on ensuring smooth traffic flow and maintenance considerations for the bridges, including water-tightness.
