Description

Device for grouting material configuration experiment of semi-flexible pavement

Technical Field

The utility model relates to a building construction material experimental facilities, in particular to a device that is used for semi-flexible road surface grout material configuration experiment.

Background

Ruts are one of the most common diseases of asphalt pavements, and are cumulative deformation of unrecoverable strains of the pavements under the action of repeated driving loads and compaction deformation under the action of driving loads. The existence of the ruts influences the smoothness of the road surface, reduces the service quality of the road, influences the driving safety, can further cause the damage of other road surfaces such as cracks, pits and the like, and shortens the service life of the road surface. The data show that the rutting rate is about 80% of the cause of maintenance of asphalt pavement in many countries. The municipal road intersection has the advantages that the damage area is prominent due to the reasons of large traffic flow, canalization of vehicle traffic, frequent vehicle braking and starting and the like, and the traffic safety is greatly influenced.

The problem of rutting at the municipal road intersection is solved, but the common measures of milling, finishing or paving a new asphalt mixture and the like cannot effectively solve the problem of stubborn rutting at the municipal road intersection.

The semi-flexible pavement is a novel pavement material formed by compounding a macroporous asphalt mixture (the porosity is 20-35%) and a cement-based material with special performance, and has the characteristics of cement concrete rigidity and asphalt concrete flexibility. The semi-flexible pavement has high bearing capacity and can effectively solve the problems of rutting and water damage of the asphalt pavement.

At present, some scientific research units at home and abroad obtain certain achievements and lay part of test road sections. However, most of the test sections are mainly used for common heavy traffic roads, rarely used for municipal roads, and rarely used for maintenance and modification of municipal roads. The analysis reason is mainly that the semi-flexible pavement cement mortar adopted in the past does not solve the performance defects of slow strength development, long curing time, large shrinkage, easy cracking and the like, and can not meet the requirements of quick open traffic and high durability of the modified municipal road. In other construction processes, the retarder is sprayed firstly, and then the surface cement paste is washed away before the internal cement paste is finally set, so that the method is not suitable for being used on municipal roads, and the waste water containing the cement paste can cause pollution, especially for the cement paste with colors. Some construction processes use a vibratory flat-bed roller to cause cement paste to permeate gaps of the asphalt mixture of the human matrix, and although the method is good, the construction process is increased. This problem can be solved if the fluidity and self-permeability of the cement slurry are increased.

In order to promote the application and development of the advanced technology of the semi-flexible pavement on the municipal road, solve the problem of stubborn rutting at the intersection of the municipal road and meet the requirements of quick open traffic and high durability after construction, the technical problems of super early strength, low shrinkage, high flow state and high permeability of the grouting material of the semi-flexible pavement are solved. The problem of semi-flexible pavement grouting material needs to be solved, the common means is to adjust the proportion of the semi-flexible pavement grouting material to realize the semi-flexible pavement grouting material, and the existing experimental device for configuring building construction materials can only configure the materials of one proportion at a time, so that the experimental efficiency is low.
