Problems solved by technology

However, most of the lower bearing layers of existing urban slate landscape roads are semi-rigid bases and cement-stabilized bases, which have the following deficiencies: 1. Under the action of rainwater and clean water, they will crack, slurp, and break, reducing the quality of urban slates. The service life of landscape roads; 2. It requires a lot of labor and long-term health maintenance to ensure its strength growth, thereby prolonging the construction period; 3. Difficult maintenance requires large-scale excavation and long-term health maintenance, which also increases The maintenance period has affected the travel and transportation of citizens

Embodiment

[0021] Take new build as an example.

[0022] as attached figure 1 As shown, the stone road of the urban pedestrian street is from bottom to top, consisting of soil foundation 1, 10cm lime stabilized soil layer 2, 1cm asphalt macadam seal layer 3, 10cm flexible asphalt stabilized macadam base layer 4, 2cm asphalt sand layer 5 and flagstone layer 6 is laid.

[0023] The specific implementation steps and technical requirements are as follows:

[0024] Lay a 10cm-thick lime-stabilized soil layer 2 on the compacted and flat soil foundation 1, and maintain it in the specified curing period to meet the strength requirements of the standard design;

[0025] After the lime-stabilized soil layer 2 reaches the design strength, lay a 1cm-thick asphalt macadam seal layer 3 on it, and roll it with a steel drum roller;

[0026] Lay a 10cm thick flexible asphalt stabilized gravel base 4 (LSPM-25) on the asphalt gravel seal 3;

[0027] A 2 cm densely graded asphalt sand layer 5 is laid on...

Abstract

The invention discloses a long-life urban slate landscape road paving structure and belongs to the field of municipal engineering. The long-life urban slate landscape road paving structure comprises a slate layer and a soil foundation, and is characterized in that a lime stabilized soil layer, an asphalt macadam sealing layer, a flexible asphalt stabilized macadam foundation layer (LSPM-25) and an asphalt sand layer are sequentially paved between the soil foundation and the slate layer from bottom to top. Compared with the prior art, the long-life urban slate landscape road paving structure has the characteristics that underground water can be quickly drained; the using performance is not influenced; the service life is prolonged; the influence on traffic caused by maintenance is reduced. The long-life urban slate landscape road paving structure has good popularization and application values, and can be widely applied to design and construction of an urban slate landscape road.

Description

technical field [0001] The invention relates to the field of municipal engineering, in particular to a pavement structure for long-life urban slate landscape roads. Background technique [0002] Urban slate landscape roads are widely used in pedestrian streets in various city centers, roads in prosperous areas, and roads in tourist areas. They can effectively enhance the characteristics of cities and tourist areas, leave a deep impression on pedestrians, and enhance the popularity of cities or tourist areas. However, most of the lower bearing layers of existing urban slate landscape roads are semi-rigid bases and cement-stabilized bases, which have the following deficiencies: 1. Under the action of rainwater and clean water, they will crack, slurp, and break, reducing the quality of urban slates. The service life of landscape roads; 2. It requires a lot of labor and long-term health maintenance to ensure its strength growth, thereby prolonging the construction period; 3. Dif...
