Thin slurry mixture paved on thin-layer cover on ice and snow melting micro-surface and paving method

Abstract

The invention discloses a thin slurry mixture paved on a thin-layer cover on an ice and snow melting micro-surface and a paving method. The thin slurry mixture comprises the following components in parts by mass: 100 parts of aggregates, 14-16 parts of ice and snow melting modified emulsified asphalt, 1-3 parts of cement, 0.5-0.8 part of auxiliaries and 7-13 parts of water. The thin slurry mixture paved on the thin-layer cover on the ice and snow melting micro-surface and the paving method have the advantages that a road can have an active snow melting function; the thin slurry mixture can be paved on the surface of a road, a pavement and a bridge deck pavement and can not cause any affect to the traditional construction equipment of a paving machine on the micro-surface and a construction process; the popularization and application of a maintenance process or thin-layer cover process can be accelerated; and the thin slurry mixture is suitable for both northern areas where ice and snow frequently take place and southern areas where freezing rain and freezing ice frequently take place.

Description

technical field [0001] The invention relates to a slurry mixture and a laying method for laying a thin-layer overlay on micro-surfaces of melted ice and snow, and belongs to the normal-temperature asphalt mixing technology for laying roads such as roads, urban roads, tunnel pavements, and airport pavements. Background technique [0002] With the development of the economy and the development of the automobile industry, the task of logistics and transportation is becoming more and more heavy, and the development of automobiles tends to be large and heavy, which brings great challenges to the operation of expressways, other highways and urban logistics traffic arteries This will further aggravate the damage of the pavement, so there is an urgent need for a fast, convenient, safe and environmentally friendly process technology for pavement maintenance and maintenance. Micro-surfacing technology is a thin-layer overlay technology that meets such needs. This technology uses speci...

Problems solved by technology

[0005] According to past experience, on the non-arterial roads of urban roads, snow removal and ice breaking are mainly relied on manually. However, with the increase of car ownership and the increase of expressways, tunnels, and bridges, it is difficult to satisfy the needs of people only by manual snow removal. travel requirements, gradually tending to mechanization and automation, reflecting the technical characteristics of safety, speed, and environmental protection
