Fabricated asphalt precast block and asphalt layer formula

Abstract

The invention relates to the field of asphalt precast blocks, in particular to a fabricated asphalt precast block and a formula thereof. The invention discloses the fabricated asphalt precast block which is characterized by comprising a bottom plate, a bonding layer and an asphalt layer from bottom to top, the asphalt precast block is in a cuboid or cube shape, the bottom plate is of a groove structure with an opening in the upper end, and the bonding layer and the asphalt layer are both arranged in the groove structure. The problems that in the prior art, sand and other pavements are generally in the environment with the large temperature difference, the temperature in the morning and evening in summer is low, the temperature in winter is low, time in winter is long, and therefore the weather resistance of the asphalt pavement is greatly reduced are solved. Industrialized standard prefabrication of the asphalt concrete pavement is adopted, the construction quality is more reliable, intelligent equipment can be adopted, the labor intensity is reduced, and meanwhile the cost is reduced.

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...

AI Technical Summary

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
