Problems solved by technology

However, there are still relatively few studies on low-grade color paving binders. In order to improve the high-temperature performance of the pavement and other road performance needs, a low-penetration high-softening point is developed, and the penetration is 40-60. Low-grade pavement color paving cement with a temperature above 50°C (non-motorized lanes) or 56°C (motorized lanes) is the current research direction

Abstract

The invention discloses a colorful pavement cementing material for a low-grade road surface, comprising the following components in percentage by mass: 30-45% of petroleum resin, 40-55% of high-aromatic mineral oil and 6-15% of modifier, wherein the high-aromatic mineral oil comprises catalytic slurry oil which is 10-20% of the total mass. The colorful pavement cementing material for the low-grade road surface, provided by the invention, has low needle penetration and high softening point, and is suitable for the low-grade road surface and has good road performances; an AC-16C asphalt mixture type is adopted in the cement material, and a road pavement material manufactured by taking the material as the cementing material has indexes including high temperature stability, water stability and low temperature stability which meet relevant national requirements and specifications, so that the colorful pavement cementing material is suitable for constructing a heavy-load traffic road surface.

Description

Technical field [0001] The present invention involves a pair of pawn -pawn converts and its preparation methods, which specifically involves a low -marked pavement pairing and preparation method. Background technique [0002] For a long time, the roads of the road are single, which looks monotonous and tedious, and paving color pavement can play a role in beautifying the environment and give people a good psychological experience.Secondly, color paving technology is applied to road identification, location instructions and environmental beautification, and achieves practical results in the organization and control of transportation. [0003] The Fushun Petrochemical Research Institute is the earliest research unit in China to develop and develop colored pavement and grilled confession. The conventional indicators of the developed products meet the requirements of my country's high-grade road asphalt standards (GB / T 15180-94). The road application test has achieved good results.Ne...
