Problems solved by technology

[0002] With the large-scale development of airport construction and test track construction in my country, these two construction projects often involve large areas of asphalt pavement sites. Although the technology and technology of traditional asphalt construction are becoming more and more mature, they are only limited to roads, etc. In linear engineering, in order to avoid the occurrence of longitudinal cold joints in highway engineering, two or three machines are often used in joint paving, while large-area asphalt paving will be divided into dozens or even hundreds of paving sections in the longitudinal direction. According to the traditional thinking, more pavers will be used. Some engineering examples adopt the method of paving with ten machines. This not only increases the cost of paving machinery, but also affects the output of rolling machinery, asphalt mixing plant and transportation of mixture. It is also a huge test, often need to configure more pavers, use multiple mixing plants and more transport vehicles

Embodiment Construction

[0020] The method for continuously rolling asphalt paving on a test track, including the following implementation steps:

[0021] a. Selection of the number of paver machines and determination of the distance between the front and rear machine positions: at least two or more paver machines are required to achieve continuous rolling paving, and the distance between the front and rear paver machine positions shall not exceed 100m, and then according to the length of each paving area Determine the number of paver according to the paving speed;

[0022] b. Treatment on the side of the pavement at the back of the pavement: before paving, first bake and heat the lower bearing layer with a blowtorch to prevent the colder lower bearing layer from absorbing the heat of the asphalt. The baking length should be longer than that of the paver The first 10~15m, the width is about 1m, across the joint position, reserve about 40cm not to be rolled when the first pavement is rolled, as the ele...

Abstract

The invention discloses a method for continuously and rollingly paving asphalt on a dynamic flat ground of a skid pad. The method comprises the step of: (a), selecting the quantity of pavers, and determining distance between a front paver and a rear paver, wherein at least two pavers are needed for realizing continuous and rolling paving, the distance between the front paver and the rear paver does not exceed 100m, and the quantity of the pavers is specifically determined according to the length of each paving range and the paving speed. According to the method, the definition of a hot joint is expanded, formation of a longitudinal cold joint is reduced, the investment of construction machinery is greatly reduced, and the construction cost is reduced.

Description

technical field [0001] The invention relates to a construction method of multi-machine joint paving for asphalt pavement construction. It improves the traditional multi-machine joint paving scheme to reduce the use of paving machines and at the same time reduce the longitudinal cold joints when paving large-area asphalt on the dynamic platform of the test site. A construction method that ensures no longitudinal cold joints within the same day. Background technique [0002] With the large-scale development of airport construction and test track construction in my country, these two construction projects often involve large areas of asphalt pavement sites. Although the technology and technology of traditional asphalt construction are becoming more and more mature, they are only limited to roads, etc. In linear engineering, in order to avoid the occurrence of longitudinal cold joints in highway engineering, two or three machines are often used in joint paving, while large-area a...
