A certain port area in Shanghai is engaged in comprehensive port services such as loading and unloading,warehousing,and distri-bution of various domestic and international trade goods such as coal,yellow sand,equipment,feed,pulp,steel,and chemical products.A large number of heavy vehicles operate in the port area and surrounding roads,causing serious damage to the roads.The road maintenance plan us-ing ordinary cement concrete is not effective and can often only last for 1-2 months.To ensure the long-term performance of roads under heavy traffic in the port area,reduce daily maintenance costs,and provide reference for the renovation and maintenance of heavy traffic roads in the port area,a continuous reinforced concrete pavement with a semi-flexible composite layer was tested for the renovation existing roads.The de-sign scheme,process characteristics,and material composition of the proposed pavement were mainly introduced.
