Prefabricated asphalt block and asphalt layer formula

Abstract

The invention relates to the field of asphalt prefabricated blocks, in particular to an assembled asphalt prefabricated block and its formula. The invention discloses an assembled asphalt prefabricated block, which is characterized in that it includes a bottom plate, an adhesive layer and an asphalt layer from bottom to top; the shape of the asphalt prefabricated block is a cuboid or a cube, and the bottom plate is a groove structure with an open upper end. Both the adhesive layer and the asphalt layer are arranged in the groove structure. The invention solves the problem in the prior art that road surfaces such as sandy ground are generally in an environment with large temperature differences, and the temperature is low in the morning and evening in summer, and the temperature is low in winter for a long time, thus greatly reducing the weather resistance of the asphalt pavement. The invention adopts the factory standard prefabrication of asphalt concrete pavement, the construction quality is more reliable, and intelligent equipment can be used, which is beneficial to reduce labor intensity and cost at the same time.

Description

technical field [0001] The invention relates to the field of asphalt prefabricated blocks, in particular to an assembled asphalt prefabricated block and its formula. Background technique [0002] Soft ground includes fields, sandy land, swamps, shoals, etc., with poor bearing capacity. When a vehicle walks on a soft ground, the tires will sag, the driving resistance of the vehicle will increase, and the adhesion coefficient will decrease, resulting in poor passing performance of the vehicle. With the development of mechanized construction, more and more construction machinery vehicles are put into operation, and it is necessary to solve the problem of vehicle passability on soft ground. [0003] The measures currently taken by the construction unit are to use prefabricated asphalt to set up temporary paved roads, so as to increase the force-bearing area between the wheels and the soft ground, so that the vehicles can not sink. Although this method has a smooth surface and no...

Problems solved by technology

[0003] The measures currently taken by the construction unit are to use prefabricated asphalt to set up temporary paved roads, so as to increase the force-bearing area between the wheels and the soft ground, so that the vehicles can not sink. Although this method has a smooth surface and no joints, The driving vibration is small and the noise is low. However, because asphalt is highly sensitive to temperature, and roads such as sand are generally in an environment with large temperature differences, the temperature is low in the morning and evening in summer, and the temperature is low in winter for a long time. Weather resistance is greatly reduced
