The Stability and Durability of Asphalt Pavement

^{Asphalt pavement has high temperature stability and low temperature crack resistance with good water stability. These characteristics make asphalt pavement less likely to flow and deform at high temperatures in summer, and less possible to crack at low temperatures in winter, while against moisture damage.}

^{Asphalt pavement tends to be stable in summer mainly because of its ability to resist flow deformation. In hot seasons, due to repeated vehicle driving, asphalt pavement may suffer from waves, drifts, rutting, congestion and other damages. However, the high-temperature stability of asphalt pavement makes it less susceptible.}

^{As for low-temperature crack resistance, this means that asphalt pavement is less likely to crack, sink, and dent when the temperature drops. Since the stiffness of asphalt pavement increases and the deformation capacity decreases as the temperature drops, under the action of external loads, part of the stress has no time to release, and stress may accumulate instead, preventing the pavement from cracking, sinking, and denting.}

^{Asphalt pavement also has good water stability. Even in rainy seasons or rainy areas, moisture is less likely to penetrate and damage the pavement structure, keeping the pavement stable.}

^{In general, asphalt pavement is stable with a long lifespan thanks to its excellent high temperature stability, low temperature crack resistance and water stability. These properties allow asphalt pavements to withstand a variety of climatic conditions, traffic pressures and still remain in good condition. It is necessary to conduct proper maintenance so as to keep up with the good work.}
