Specifications for construction of aerodrome cement concrete pavement
1 General provisions
1.0.1 The specifications is developed in order to meet the needs of civil airport construction in China, clarify the technical requirements for cement concrete pavement slab construction and ensure its construction quality.
1.0.2 The specifications is applicable to the construction of cement concrete pavement slab of the airfield area pavement and road surface (including runway, taxiway, apron, shoulder, runway blast pad, airfield perimeter road and ground service road) of constructed, renovated and extended civil airports (including the civil part of joint-used airport by military and civil units). It is applicable to the construction of cement concrete pavement slab for airport, and in case of special requirements, it shall be implemented according to the design documents.
1.0.3 For the construction of cement concrete pavement slab, a perfect quality assurance system shall be established, and corresponding technical measures shall be taken according to the requirements of the design documents and based on the hydrogeological, engineering geological, meteorological and construction conditions to ensure the engineering quality.
1.0.4 For the construction of cement concrete pavement slab, a safe production and environmental protection management system shall be established to ensure the construction safety and reduce environmental pollution. In the construction process, attention shall be paid to saving land, reducing energy and material consumption, and protecting the environment.
1.0.5 For the construction of cement concrete pavement slab, new technologies, new materials, new equipment and new processes shall be adopted.
1.0.6 The construction of cement concrete pavement slab shall meet those specified both in the specifications and in the current relevant rules and standards of the nation and the profession.
