Abstract

The invention discloses a pavement colored cold filling material. The pavement colored cold filling material comprises the following raw materials in parts by weight: 4.2-4.6% of colored cold filling liquid, 88-92.7% of machine-made sand, and 2.2-2.7% of color powder. The preparation method comprises the following steps: adding machine-made sand with the particle size of 3mm in an asphalt concrete mixing plant, adding 2.7% of powdery color powder; The pavement colored cold filling material effectively solves the problems of high cost of small-area colored pavement construction and the materials for pit slot repairing, and also solves the problems that the traditional colored cold filling material cannot be insulated during transport process, so that the colored asphalt concrete can only be wasted. The cost is low, the method is benefit for construction, on-site heating is not required, the pavement colored cold filling material can be used while the bag is removed, and the usage is simple and convenient.

Description

technical field [0001] The invention relates to a pavement construction technology, in particular to a pavement colored cold patching material and a preparation method thereof. Background technique [0002] At present, the paving of colored pavement mainly relies on the construction technology of hot-mixed and hot-paved colored asphalt concrete stirred by the existing large-scale asphalt mixing plant. Hot-mixed and hot-paved colored asphalt concrete is still used. Due to the small batch of hot-mixed colored concrete required, the cost of each start-up of the asphalt mixing plant is not less than 20,000 yuan, and the asphalt pipeline must be thoroughly cleaned after each use, resulting in colored The cost of asphalt concrete has increased significantly, and it consumes a lot of energy such as diesel, kerosene and coal electricity, which is not conducive to energy conservation and environmental protection. Especially when repairing potholes, only a few tons of colored asphalt...
