Problems solved by technology

Although this utility model achieves the purpose of simple assembly and shortening the construction period, the base plate must be installed on the base, and the volume of the base is much larger than the base plate, so that the amount of concrete is huge, and the base plate and the base plate are connected through the The connecting parts are connected by screws, base plates and nuts, and the joints are prone to breakage under the condition of long-term vehicle load

Embodiment 1

[0062] Such as figure 1 As shown, a prefabricated concrete traffic pavement is formed by splicing pavement prefabricated parts. The pavement prefabricated parts include an upper layer of wear-resistant layer 3 and a lower layer of stressed structure layer 2. The wear-resistant layer 3 and the stressed structure Layer 2 is fixedly connected, and there is a gap at the joint of the pavement prefabricated parts that are spliced ​​with each other, and concrete is poured in the gap to form a gap stress layer 4. The thickness of the wear-resistant layer 3 is 20mm, and the thickness of the structural stress layer is 80mm.

[0063] The wear-resistant layer is cast from modified ECC ductile ultra-high performance concrete, and the modified ECC ductile ultra-high performance concrete includes the following raw material components in parts by weight:

[0064] Strength not less than 42.5 grade Portland cement or 750 parts of ordinary Portland cement;

[0065] 32 parts of silica fume with ...

Abstract

The invention discloses an assembled concrete traffic pavement which is formed by splicing pavement prefabricated members, wherein each pavement prefabricated member comprises an upper wear-resisting layer and a lower stress structure layer, and the wear-resisting layer is fixedly connected with the lower stress structure layer; gaps are reserved at the spliced joints of the mutually spliced pavement prefabricated members, and a gap stress layer is formed on the gap poured concrete. The invention further discloses a construction method of the assembled concrete traffic pavement. The pavement prefabricated members disclosed by the invention are light in structure, high in strength, and good in wear resistance, and are integrally fabricated and spliced to form a traffic pavement, and the pavement is short in construction period and is not limited by weather and seasons.

Description

technical field [0001] The invention belongs to the field of traffic road construction, in particular to an assembled concrete traffic road surface and a construction method thereof. Background technique [0002] Recently, with the acceleration of urbanization and the country's efforts to improve people's livelihood, new traffic road construction projects and old road repair and expansion projects have been launched one after another. Ordinary concrete, as the main rapid infrastructure material, is widely used in the construction of traffic roads. However, concrete is used to construct roads in the form of cast-in-place, which is easily affected by weather, climate, temperature, humidity, etc. The pouring volume is large, and it is prone to cracking due to temperature rise and poor maintenance, which will reduce the service life of the pavement, and cause pavement fracture and partial subsidence. Moreover, the maintenance period and construction period after concrete pouri...
