Embodiment 1

[0063] A construction technique for cement-emulsified asphalt mortar penetrating semi-rigid pavement, comprising the following steps:

[0064] 1. Formation of cement emulsified asphalt mortar penetration type main structure;

[0065] 2. The roughening treatment of the formed main structure road surface;

[0066] 3. Laying the adhesive layer: apply the adhesive to the roughened road surface to form an adhesive layer;

[0067] 4. Lay the anti-slip and wear-resistant layer: before the adhesive material is dried and solidified, spread the anti-slip and wear-resistant material on the adhesive layer, and after drying for 2-3 hours, proceed to the next step;

[0068] 5. Coating anti-icing layer: After stirring the anti-icing coating evenly, roll it onto the anti-skid and wear-resistant layer;

[0069] 6. Heating and curing: After the anti-icing coating layer is dried for 1.0-1.5 hours, use the road surface dryer to heat and cure it, that is, complete the construction treatment of t...

Abstract

The invention discloses a construction process of a cement emulsified asphalt mortar penetrating semi-rigid road surface. The construction process comprises the following steps that 1, a cement emulsified asphalt mortar penetrating main structure is formed; 2, a main structure road surface is subjected to roughening treatment; 3, an adhesive layer is laid; 4, an anti-skid wear-resistant layer is laid; 5, an anti-icing layer is coated; 6, heat curing is performed; and 7, traffic is opened / initial maintenance is performed. In the main structure of the construction process of the cement emulsified asphalt mortar penetrating semi-rigid road surface, the cement emulsified asphalt mortar penetrating semi-rigid road surface has high compressive strength and shearing strength, and the bearing capacity and the high temperature stability of the road surface are greatly improved; and meanwhile, the surface performance of the road surface is further optimized by a wear-resistant and anti-icing structure of the surface layer of the road surface, and the wear-resistance and anti-icing performance are enhanced.

Description

technical field [0001] The invention relates to the technical field of road construction and maintenance, in particular to a construction process of cement emulsified asphalt mortar semi-rigid pavement. Background technique [0002] The pavement with cement (second binder)-asphalt (first binder) composite material as the binder has both the advantages of rigid pavement and flexible pavement, and shows the mechanical characteristics of semi-rigid and semi-flexible. It is usually called semi-rigid and semi-flexible. Flexible pavement, also known as semi-rigid pavement, is currently mainly realized through two construction methods: the first method: adding rigid material cement mortar or pouring cement grout into the asphalt mixture matrix to improve the anti-rutting ability of the pavement, It also has anti-slip durability and low-temperature crack resistance. In terms of construction technology, this method is divided into mixing method and penetration method. The penetrati...
