Embodiment 1

[0023] The invention provides a kind of antiskid type asphalt pavement construction technology, comprises the following steps:

[0024] S1: First, design the selected road surface, including slope, turning curve, and clear the sundries and trees on the designed road surface, completely clear the road surface, fill the pits on the road surface, and use the tools for the bumps on the road surface Excavate, fill and compact the loose parts of the road surface;

[0025] S2: After the base course is cleaned, the asphalt prepared by mixing according to the actual use ratio will be spread on the cleaned road surface. During construction, the asphalt sprinkler will be used to spray the asphalt. The spraying temperature should be determined according to the construction temperature and the asphalt grade. In general, the coal tar pitch should be 70°C-110°C, the petroleum pitch should be 120°C-160°C, and the emulsified asphalt should be spread at room temperature;

[0026] S3: In the pa...

Abstract

The invention discloses an anti-skid asphalt pavement construction process which comprises the following steps: firstly, designing a selected pavement, including gradient and turning curve, removing sundries and trees on the designed pavement, completely cleaning the pavement, filling pits in the pavement, removing bulges on the pavement through a tool, and filling and pressing loose parts of thepavement; after base layer cleaning, paving asphalt which is prepared by stirring according to an actual use ratio on the cleaned pavement; and during construction, using an asphalt distribution truckto spray asphalt, the distribution length being coordinated with the mineral aggregate distribution capacity, determining the asphalt distribution temperature according to the construction air temperature and the asphalt label. Under the general condition, the temperature of coal asphalt should be 70-110 DEG C, the temperature of petroleum asphalt should be 120-160 DEG C, and emulsified asphaltshould be distributed at the normal temperature. The antiskid asphalt pavement construction process is good in smoothness and stable and comfortable in driving, the asphalt semi-rigid base layer has the characteristics of high strength, good stability, high rigidity and the like, and asphalt construction is fast.

Description

technical field [0001] The invention belongs to the technical field of asphalt, and in particular relates to an anti-slip asphalt pavement construction technology. Background technique [0002] Asphalt is a waterproof, moisture-proof and anti-corrosion organic gelling material. Pitch can be mainly divided into three types: coal tar pitch, petroleum pitch and natural pitch. Among them, coal tar pitch is a by-product of coking. Petroleum asphalt is the residue after distillation of crude oil. Natural bitumen is stored underground, and some form ore layers or accumulate on the surface of the earth's crust. [0003] Asphalt is mainly used in industries such as coatings, plastics, and rubber, as well as paving roads, etc. However, the existing asphalt pavement will be easily damaged due to insufficient construction technology when it is used, which will cause inconvenience to travel and needs further improvement.
