Road asphalt price Road asphalt characteristics

Asphalt is very common in our lives and is widely used in many fields. But the most commonly used one is road paving. Pitches are hydrocarbons of varying molecular weights and are also non-metallic derivatives. Asphalt is a very good high-viscosity organic liquid. It usually appears in a liquid state and is black in color. It has very good waterproof and anti-corrosion properties. But many friends are not very familiar with asphalt, so next the editor will tell you some knowledge about asphalt.

Road asphalt Features

Asphalt pavement is a pavement structure in which a certain thickness of asphalt mixture is laid on a flexible base layer or a semi-rigid base layer as the surface layer. Compared with gravel pavement, this kind of pavement has greatly improved strength and stability. Compared with cement concrete pavement, asphalt pavement has a smooth surface and no seams, small driving vibration, low noise, fast opening to traffic, and simple maintenance. It is suitable for phased construction of pavement and is an important structural form of pavement in my country.

The disadvantage of asphalt pavement is its high temperature sensitivity. The strength decreases in summer. If it is not properly controlled, the road surface will become soft and oily, or it will be damaged by shearing. Asphalt materials become brittle at low temperatures and may cause pavement cracking.

Asphalt pavement is divided into two types according to its strength composition principle: interlocking type and graded compact type. The interlocking asphalt pavement uses asphalt surface treatment, asphalt penetration and asphalt gravel paving, and is a sub-high-grade pavement. Compact asphalt pavement is paved with various types of asphalt concrete, asphalt mastic gravel, etc. It has high density and small pores. It is the asphalt pavement with the highest strength and stability and is a high-grade pavement.
