Problems solved by technology

[0002] Traditional asphalt pavement maintenance methods include asphalt surface treatment method, slurry seal method, and thin layer overlay method. The road section with a finer grade has poor anti-skid performance, and the road section with a thicker grade is easy to fall off, resulting in the whitening of the original road surface

Embodiment Construction

[0014] The fiber gravel synchronous sealing layer pavement maintenance method of the present invention comprises the following steps:

[0015] 1) Spray the first layer of modified emulsified asphalt

[0016] Spray the modified emulsified asphalt that meets the technical requirements evenly on the original road surface, and the spraying amount is generally converted into pure asphalt to be 0.15kg / m 2 ~0.25kg / m 2 Control, the performance index of modified emulsified asphalt is shown in Table 1 below.

[0017] Table 1 Test results of modified asphalt

[0018]

[0019] 2) Simultaneously spread fiber and gravel aggregate

[0020] While spraying the first layer of modified emulsified asphalt, simultaneously spread fiber and crushed stone aggregate, the full coverage rate of the aggregate should be close to 100%; the fiber used in this step is ordinary glass fiber, with a length of 50-60mm, which should meet The requirements shown in Table 2; the aggregate specifications are b...

Abstract

The invention relates to a fiber-broken stone synchronous-sealing pavement maintenance method, relates to the pavement maintenance method, and is suitable for preventive maintenance treatment for roads. The method includes the steps: 1) spraying modified emulsified asphalt; 2) synchronously spreading fibers and broken stone aggregates; 3) adopting a 16 T-or-more rubber wheel road roller for rolling the pavement obtained in the step 2) for 2-3 times with the rolling speed of 2-3.5 km / h, and followed by cleaning and recycling loose aggregates with an aggregate recycling device; and 4) after determining that the pavement obtained in the step 3) basically has no loose aggregates, spraying the modified emulsified asphalt, and closing traffic for 2 h-6 h, and then allowing vehicles to pass through. The water sealing performance and the anti-abrasion performance of the pavement can meet the preventive maintenance requirements of all kinds of roads, and the anti-sliding performance is excellent.

Description

technical field [0001] The invention relates to a pavement maintenance method for a synchronous sealing layer of fiber gravel and relates to a pavement maintenance method, which is suitable for preventive maintenance treatment of asphalt pavement. Background technique [0002] Traditional asphalt pavement maintenance methods include asphalt surface treatment method, slurry seal method, and thin layer overlay method. Road sections with finer grades have poor anti-skid performance, and road sections with thicker grades are easy to fall off, resulting in whitening of the original road surface. Therefore, a new preventive maintenance method is needed to comprehensively solve the problem, and the synchronous fiber gravel seal is a good choice. Contents of the invention [0003] The purpose of the present invention is to provide a kind of fiber gravel synchronous sealing layer pavement maintenance method for above-mentioned deficiencies, be used for adapting to road surface pre...
