Description

Technical Field

[0001] This invention belongs to the field of temperature dissipation rate testing technology, specifically relating to a device and method for testing the temperature dissipation rate of asphalt concrete panels under high wind conditions. Background Technology

[0002] After asphalt concrete is poured, it generates a large amount of heat of hydration, causing the concrete temperature to rise. Because the elastic modulus of early-age concrete is lower than that of late-age concrete, cracks or fissures are easily formed during the temperature drop process. Effective measures to control the temperature of early-age concrete are crucial for temperature control and crack prevention in asphalt concrete. In windy conditions, asphalt concrete is affected by multiple factors. Asphalt concrete temperatures decrease, and strong winds accelerate heat loss from the surface, causing a rapid temperature drop. This affects the paving quality and compaction effect, as the temperature of the asphalt mixture significantly impacts its performance. Under wind force, the cooling rate of the asphalt concrete surface may be much greater than that of the interior, resulting in a significant temperature difference between the surface and the interior. This temperature difference can lead to defects such as cracks and hollow areas, affecting the durability and service life of the pavement. Currently, there is a lack of comprehensive testing equipment and methods for measuring the temperature loss rate of asphalt concrete panels to fully understand the impact of strong winds on temperature loss.
