In order to reveal the mechanical properties of sandstone cement stabilized gravel, samples were prepared according to the principle of vertical vibration. The effects of rock type, cement content and ageing on compressible strength and splitting strength were studied. The results show that sandstone origin and cement content will affect the mechanical properties of cement stabilized crushed stone base. The 4.0% cement content is the turning point of the curve of infinite compressible strength with healthy age; the softening coefficient of sandstone cement stabilized crushed stone increases first and then decreases with the increase of curing time; the mechanical properties of sandstone cement stabilized crushed stone from different origins Meet the specification requirements, the basic layer could be applied.
