Problems solved by technology

The ultra-large slope asphalt pavement of the high-speed ring road of the SAIC-Volkswagen Turpan test site is the first special asphalt road in China. During the paving process of the super-large slope, if there is a transverse joint construction, the cooling method is all natural cooling. The transverse joint refers to the newly laid on the same plane. The joint between the asphalt layer and the previously laid asphalt layer, the SAIC Turpan test site is located in Turpan, Xinjiang, where the temperature is high, and the temperature drops slowly during the asphalt paving period. If the temperature at the joint is not lowered in time and the strength is not enough, it will cause the rolling equipment to go back and forth multiple times to the construction joint to affect the flatness and stability, and the width of the slope is long, so it is necessary to ensure the overall timely cooling. In order to ensure the flatness and stability, there is no solution in the prior art for how to speed up the reduction of the joint temperature of asphalt paving joints on super-large slopes in the proving ground

Embodiment Construction

[0014] combined with Figure 1~3 The present invention is further described:

[0015] A joint construction method for the inclined surface of the ring road of a proving ground, comprising the following steps:

[0016] A. According to the design requirements of the slope of the ring road, lay the slope base in advance, and then lay the graded crushed stone mixture on the slope base;

[0017] B. Begin to pave the asphalt layer in sections along the length direction of the slope of the ring road, lay stainless steel pipe 10 in front of the cut-off face of the asphalt layer, and lay the stainless steel pipe 10 along the slope of the slope of the ring road from top to bottom;

[0018] C, start from the truncated surface of the asphalt layer, adopt a paver to continue laying a new asphalt layer on the top of the stainless steel pipe 10;

[0019] D, then arrange the road roller to roll the new asphalt layer along the length direction of the slope of the ring road, use the water inj...

Abstract

The invention discloses a joint construction method of an inclined surface of a ring road in a test yard. The method comprises the following steps: A, according to the design requirements of the inclined surface of the ring road, laying an inclined surface base layer in advance, and then laying a graded crushed stone mixture on the inclined surface base layer; B, laying the graded crushed stone mixture on the inclined surface base layer; B, star to spread that asphalt layer section by section along the length direction of the inclined surface of the extension ring road, laying a stainless steel pipe in front of the truncation of the asphalt lay, and laying the stainless steel pipe along the slope surface of the inclined surface of the extension ring road from the top to the bottom; C, starfrom that truncated surface of the asphalt lay, adopting a paver to continuously lay a new asphalt layer on the stainless steel pipe; D, arrange a roller to roll that new asphalt lay along the lengthdirection of the inclined surface of the ring road, continuously supplying wat from the upper end to the lower end of the stainless steel pipe by adopting a water injection pipe, and cooling the joints of the new asphalt layer and the paved asphalt layer; E, aft meeting that joint temperature of the new asphalt lay and the paved asphalt layer, the water injection pipe stops the wat supply and thestainless steel pipe is plugged with cement slurry.

Description

technical field [0001] The invention belongs to the field of high-speed ring road construction in a test track, and in particular relates to a joint construction method for the inclined surface of a test track ring. Background technique [0002] With the large-scale development of test track construction in my country, the traditional concrete pavement can no longer meet the high-precision requirements of the current test track road surface smoothness, while the technology and technology of asphalt pavement construction are becoming more and more mature. For example, in the paving of curved asphalt at Shanghai Volkswagen Proving Ground and Guangde General Motors Proving Ground, German bridge-type curved surface pavers are used to pave the entire width, while the Guangben Proving Ground and Nanjing Ford Proving Ground use Japanese curved surface paving. The paving machine is divided into auxiliary paving. The ultra-large slope asphalt pavement of the high-speed ring road of ...
