Adopting the composed cement concrete pavement of machine-made sand concrete and natural sand concrete not only can reduce to dig the natural river sand and protect the environment, but also can ensure the functional requirements of the cement concrete surface layer. This paper studies the differences of work performances and mechanical properties through contrasting machine-made sand concrete and natural sand concrete, then it carries on mechanical properties tests of the composed concrete samples towards the lower layer 100 mm of machine-made sand concrete and the upper level layer 50 mm of natural sand concrete. Besides it also explores a perfect paving opportunity of the upper natural sand concrete.
