摘要:Influence of water content on the resilience modulus for silt soil in Yellow River alluvial plane is studied by laboratory tests. And it's found that resilience modulus decrease dramatically when the water content exceeds the optimum. So the subgrade can't support the pavement structure enough, which could make the fatigue life of semi-rigid base little than the design value. Basing on the distribution of the water content in real, the silt subgrade is divided into three parts in accordance with the difference of resilience modulus. Then, the tensile stress and fatigue life of semi-rigid base is gotten, and results show the strength decay of subgrade reduced the fatigue life of semi-rigid base up to 50%, which exposes the causes of early damage of semi-rigid base asphalt pavement on silt subgrade.
