With the continuous acceleration of urbanization and the growth of transportation demand, road construction and maintenance have become an important part of urban development. In this context, as a key equipment in road construction, the technological innovation of emulsified asphalt spreaders is of great significance to promoting sustainable road construction. This article will explore how emulsified asphalt spreaders can help sustainable road construction from the perspective of technological innovation.

The purpose of using emulsified SBS modified asphalt is mainly to improve high temperature stability; low temperature shrinkage cracking resistance; early strength, cohesion, adhesion strength; water peeling resistance; fatigue resistance; and extend the life of the pavement. In particular, emulsified modified asphalt with ultra-high SBS and asphalt content will complement advanced maintenance equipment and processes.

Emulsified asphalt that increases road adhesion plays an important role in improving road service life due to its excellent performance. The following is a detailed analysis of emulsified asphalt in improving road adhesion and service life:

Don't know what is "permeable layer, adhesive layer, and sealing layer? Or don't know the "permeable layer, adhesive layer, and sealing layer construction sequence" please look over here and read this article carefully!
Let's talk about the construction sequence first. The permeable layer oil must be sprayed within 6 hours after the base layer is rolled. The permeable layer oil uses emulsified asphalt PC-2. The amount can be determined by trial spraying at 1.5 liters per square meter, and the penetration depth is not less than 5mm. After spraying the permeable layer oil, the emulsified asphalt PC-1 lower sealing layer is paved. The amount of emulsified asphalt is 1.0 liters per square meter, the aggregate particle size is 0.5 to 1cm, and the thickness should not be less than 0.6 cm. Before paving asphalt concrete, the adhesive layer oil must be sprayed on the upper and lower layers of the lower sealing layer and on the sides of curbs, rainwater outlets, inspection wells and other structures. The adhesive layer oil is Use emulsified asphalt PC-3, with a dosage of 0.5 liters per square meter.

In highway construction, asphalt mixing station plays a vital role. As a kind of equipment integrating intelligence, high efficiency and environmental protection, asphalt mixing station provides strong support for improving the quality of highway construction. This article will introduce the relevant knowledge of asphalt mixing station in detail to help readers understand this key equipment.
Asphalt mixing station is a kind of equipment specially used for producing asphalt concrete, which is widely used in highway, municipal road, bridge and other engineering construction. Asphalt concrete is a kind of building material mixed with asphalt, gravel, sand and other materials. It has the characteristics of strong durability and good compressive resistance. It is an ideal material for highway construction.

In the construction industry, asphalt mixing plants play an important role. As a kind of equipment for producing asphalt mixture, asphalt mixing plants provide necessary raw materials for engineering projects such as road construction and bridge paving. This article will introduce the background, characteristics, functions, principles and main components of asphalt mixing plants in detail, and look forward to its future development trends and application prospects.
