Slag sand-brucite powder AC-20C asphalt mixture: building high-per

Facing the high standards and environmental protection requirements of modern road construction, an innovative material combination - AC-20C asphalt mixture reinforced with slag sand and brucite powder, is gradually emerging. This combination is not only committed to improving road performance, but also taking solid steps to promote circular economy and environmental protection.

Slag sand: smart application of circular economy

Slag sand, as a model of reuse of industrial by-products, its application in asphalt mixture is a vivid practice of the concept of resource recycling. It can not only reduce material costs and reduce environmental burden, but also optimize key performance indicators such as high-temperature stability, low-temperature crack resistance, wear resistance and water stability by adjusting the gradation of the mixture. The addition of slag sand opens up a new path for the green transformation of road materials.

Brucite Powder: Nature’s Choice Performance Enhancer

Compared with fiber form, brucite powder also shows extraordinary potential as a modifying additive. Brucite powder (Mg(OH)_2), with its unique chemical properties and good dispersion, can significantly improve the overall performance of AC-20C mixture. Incorporating brucite powder into asphalt mixtures can not only enhance the high-temperature stability and water stability of the mixture, reduce rut formation and water penetration, but also improve the flexibility at low temperatures to a certain extent, reduce the occurrence of cracks, and extend the life of the mixture. Road life.

AC-20C: Green upgrade of high-performance asphalt concrete

As a representative of medium-grained asphalt concrete, AC-20C is widely used in the surface layer and mid-surface layer of high-grade highways. Its performance requirements are strict, and it needs to have excellent anti-skid and abrasion resistance as well as good compactness and strength. The introduction of slag sand and brucite powder not only meets the basic performance requirements of AC-20C, but also adds the dual advantages of environmental protection and economy, making it a bright green pearl in the field of road construction.

Scientific research exploration: multi-dimensional performance evaluation

In order to fully verify the superiority of the slag sand-brucite powder AC-20C mixture, a series of scientific and rigorous tests are essential. From rutting tests to low-temperature bending tests, from freeze-thaw splitting tests to submerged Marshall tests, each test is a rigorous test of its durability, stability and adaptability. At the same time, through advanced data analysis methods, such as the gray entropy method, parameters such as the dosage and particle size of slag sand and brucite powder are accurately adjusted to maximize performance.

A win-win strategy for economy and environmental protection

The AC-20C asphalt mixture using slag sand and brucite powder is not only an innovative practice in material science, but also a perfect balance between economy and environmental protection. The recycling of slag sand and the utilization of natural resources of brucite powder jointly promote the sustainable development of road construction and demonstrate the infinite possibilities of future road engineering materials.

The research and application of slag sand-brucite powder AC-20C asphalt mixture marks a solid step in the road construction field in pursuing the integration of high performance and environmental protection, and provides a strong basis for the realization of green transportation infrastructure construction. Strong support.
