In asphalt pavement construction, there are two common paving methods: route method and balance beam method. This paper will introduce the construction steps and matters needing attention of these two methods.

Construction preparation work

Before construction, materials that have passed the investigation and test must be purchased for preparation, the mixture ratio design should be well done and reported to the supervision engineer for approval, and all kinds of raw materials should be inspected for conformity.

Laying method

The bottom, middle and surface layers are constructed by route method, and the surface layer is constructed by balanced beam method. The paver runs evenly, and the walking speed matches the output of the mixing station, so as to ensure that the paved pavement is paved evenly and uninterrupted.

Paving temperature

The paving temperature of asphalt concrete is adjusted according to the temperature change. In general, the normal construction should be controlled at not less than 1 10- 1300C and not higher than 1650C. Check at any time during paving and make records.

♂? Paving quality

During paving, check the paving quality at any time. When there is segregation and material shortage at the corner, it should be replenished and replaced manually in time. Where the paver can't work, with the consent of the supervision engineer, artificial paving construction will be adopted.
