Environment-friendly road surface paving material

Abstract

The invention discloses an environment-friendly road surface paving material. The environment-friendly road surface paving material is characterized by comprising the following substances in parts by weight: 60-75 parts of gravels, 11-13 parts of ruditapes philippinarum shell powder, 9-13 parts of razor clam shell powder, 8-13 parts of clam shell powder, 2-6 parts of a thickening agent, 15-20 parts of urea formaldehyde resin, 12-16 parts of polytetrafluoroethylene gum, 3-8 parts of organic silicon modified epoxy resin, 7-13 parts of sodium carbonate, 3-6 parts of calcium carbonate, 9-14 parts of potassium dichromate and 3-5 parts of fillers. The environment-friendly road surface paving material has the beneficial effects that the construction workability is very good; the opened traffic is short and the effective compaction time is long, so that the road construction quality is improved.

Description

technical field [0001] The invention relates to an environment-friendly pavement material. Background technique [0002] At present, more than 90% of paved road projects in my country are paved with asphalt mixture. Compared with cement pavement, asphalt pavement has the advantages of excellent road performance, convenient maintenance, low driving noise, and low construction cost. But there are following deficiencies in the existing asphalt mixture in the construction and use process: 1, construction under high temperature state easily causes asphalt aging, because traditional matrix asphalt and modified asphalt have high viscosity under high temperature state, so high construction temperature is very easy It causes the aging of asphalt, which affects the long-term performance and service life of asphalt pavement, so that early diseases occur frequently. This is also a main reason for the frequent maintenance of roads that cause complaints from the people and headaches from...

But there are following deficiencies in the existing asphalt mixture in the construction and use process: 1, construction under high temperature state easily causes asphalt aging, because traditional matrix asphalt and modified asphalt have high viscosity under high temperature state, so high construction temperature is very easy It causes the aging of asphalt, which affects the long-term performance and service life of asphalt pavement, so that early diseases occur frequently, which is also a main reason for the frequent maintenance of roads that cause complaints from the people and headaches from the government.

2. The period suitable for annual construction is short. In order to ensure the uniformity and compactability of the asphalt mixture, the paving temperature of the asphalt pavement should not be lower than 125 degrees Celsius. Due to the rapid heat dissipation of the mixture, it is easy to cause insufficient compaction.

Due to the long period of prohibition of construction, it seriously affects the process of road construction and maintenance and reconstruction, and also leads to huge waste of idle construction machinery and personnel.

At the same time, in order to catch up with the construction period, many projects, including some special projects, cannot guarantee the time and temperature of road surface rolling, resulting in frequent occurrence of construction quality such as insufficient compaction, which directly affects the use quality and service life of the road surface
