What is a key factor in the quality of a transverse joint?

The temperature of the mix used is a critical factor in the quality of a transverse joint because it directly influences the workability and bonding of the materials. When the mix is properly heated, it ensures that the asphalt binder remains effective, allowing for better fusion of the layers at the joint. If the temperature is too low, the materials may not adhere properly, leading to issues such as cracking or delamination over time. This adherence is essential for maintaining the structural integrity and longevity of the roadway. Additionally, a properly heated mix allows for more effective compaction, which contributes to the overall strength of the transverse joint.

While other factors like joint width, depth, and visual appearance may play roles in the overall performance and aesthetic of the joint, the temperature of the mix is fundamental to achieving a strong and durable connection between pavement sections.
