ABSTRACT

Gussasphalt concrete is a material whose construction demands considerable asphalt content, extreme mixing temperature, and effective mineral powder content. However, elevated temperatures can accelerate the ageing of asphalt, resulting in a poor high-temperature performance of Gusshalt concrete. Engineers are trying to determine how to optimize asphalt concrete's high-temperature performance while ensuring that it performs well at low temperatures and is workable simultaneously. Engineers can increase Guss asphalt's high-temperature performance by optimizing concrete preparation, finding appropriate components, and altering the mineral powder content. To improve the high-temperature performance of Guss asphalt, Trinidad Lake asphalt, rock asphalt, and polymer-modified asphalt are commonly used. The proportion of their addition to a specific bridge has been investigated. A new type of Guss asphalt called embedded asphalt is prepared using a new paving method that can improve the concrete's elevated-temperature performance. Additionally, the optimized stirring time for different Guss asphalt concrete and modifiers has been tested to determine its influence on various performances of Guss asphalt concrete. Workability, high-temperature performance, and low-temperature performance are all balanced in Guss asphalt concrete improvement. When optimizing high-temperature performance, all factors must be considered.
