A kind of asphalt pavement and its construction method

Abstract

The invention discloses an asphalt pavement, which comprises a base layer, a gravel cushion layer laid on the base layer, a water collection part arranged on the base layer, and an asphalt layer laid on the gravel cushion layer. The water collection part includes a water storage beam fixed on the base layer, reinforcing beams fixed on both sides of the water storage beam and a water collection pipe fixed on the water storage beam, the interior of the water storage beam is hollow, And the water collecting pipe is connected with the interior of the water storage beam; the two ends of the water storage beam are respectively arranged on both sides of the road, the water storage beam is arranged in the gravel cushion, and the upper end of the water collecting pipe is connected The upper surface of the asphalt layer is connected. The invention has the following advantages and effects: the asphalt pavement can absorb and store rainwater, and evaporate the stored rainwater when the weather is hot, reducing the temperature on the asphalt pavement, thereby achieving the effect of improving the temperature environment on the asphalt pavement.

Description

technical field [0001] The invention relates to the construction field, in particular to an asphalt pavement and a construction method thereof. Background technique [0002] Asphalt pavement refers to various types of pavement paved with asphalt materials mixed with mineral materials. Asphalt binder improves the ability of paving aggregates to resist road damage from driving and natural factors, making the pavement smooth and less dusty. Water permeable and durable. Therefore, asphalt pavement is the most widely used high-grade pavement in road construction. However, in the process of continuous urban development and construction, public buildings, residences, and road construction harden the surface environment, destroying the surface water cycle, resulting in reduced air humidity, increased temperature, and increased dust in the city, forming urban pollution. "heat island effect". In order to improve the current situation of the water cycle in the city and make the city...

AI Technical Summary

Problems solved by technology

However, the existing asphalt pavement structure is relatively simple, and the asphalt is directly laid on the base layer, and the asphalt does not have the function of water permeability, so it is difficult to alleviate the urban heat island effect

In addition, the existing construction method of asphalt pavement uses a compactor to compact the asphalt pavement directly, which is difficult to adapt to the construction of new structure asphalt pavement
