Frame compact type cement stabilized macadam base pavement structure

Abstract

The invention discloses a frame compact type cement stabilized macadam base pavement structure, comprising a medium coarse sand layer, a cement stabilized macadam base, an intermediate structure and a frame compact type asphalt concrete surface layer, wherein the cement stabilized macadam base is paved on the medium coarse sand layer; the intermediate structure is paved on the cement stabilized macadam base and comprises a plurality of laminated interlayers, each interlayer comprises a plurality of cement stabilized macadam regions and frame compact type asphalt concrete regions paved at intervals at the same level, the cement stabilized macadam regions between any two adjacent interlayers are mutually staggered, the frame compact type asphalt concrete regions between any two adjacent interlayers are mutually staggered, and one reinforcing mesh is paved in each cement stabilized macadam region. The frame compact type cement stabilized macadam base pavement structure improves the load-bearing ability of the pavement structure and enhances the durability thereof.

Description

technical field [0001] The invention relates to a cement-stabilized crushed stone base pavement structure with dense skeleton. Background technique [0002] Although my country's cement pavement structure has a history of decades of development, its design method is basically established on the basis of a series of research results in the 1970s, 1980s and early 1990s, influenced by the technological level at that time. Restrictions, relying on low-grade roads, small loads of traffic vehicles, slow running speed, and backward construction technology. In recent years, with the development of the economy and the improvement of the technical level, the road traffic conditions have undergone great changes. The traffic capacity and service level of some expressways can no longer meet the demand, and urgently need to be upgraded. [0003] The development of the road transport industry is closely related to the development level of the national economy, the income level of residents...

AI Technical Summary

Problems solved by technology

With the rapid development of the national economy and the growth of material flow, the demand for road transportation is also increasing. The general road structure cannot be transported better. Some road structures have poor performance and will be damaged after a certain period of use. The situation is very serious, and it is relatively complicated to repair, which is not conducive to saving construction costs, but also affects normal road transportation. In addition, it is also lacking in anti-skid performance

[0004] With the continuous development and construction of the city, its urban roads are also under continuous development and construction, and the crossing pipes under the urban roads are also the key projects of the city. Due to the improvement of modern materials and the popularity of cars, there are more and more cars on urban roads. More and more, this will cause cars to oppress urban roads, thereby oppressing the crossing pipes, resulting in damage to the crossing pipes, and it needs to be repaired, and this kind of project takes a long time and causes more congestion to modern traffic , causing unnecessary losses and increasing costs
