Research on Mixture Proportion Design of Manufactured Sand Asphalt Concrete for Expressway
This paper combines specific examples to determine the high-quality mixture proportion of manufactured sand asphalt concrete.From five perspectives of strength,anti-shrinkage deformation,impermeability,etc.,it compares natural sand concrete and manufactured sand asphalt concrete.The final conclusion is that compared with natural sand concrete,manufactured sand asphalt concrete has better mechanical properties,stronger durability,lower cost,more friendly to the environment,and higher economic and environmental benefits.
