Regenerated type road cold-repairing material

Abstract

The invention relates to a regenerated road cold feeding material, which comprises 56-87% milling material, 0.08-0.34% cold feeding additive, 0.87-1.6% diesel, and stones. The invention adds stone, feeding liquid, diesel, and macromolecule activate modified additive into the milling waste of highway, to be heated and mixed, to save material and reduce the pollution, while the added macromolecule activate modified additive can resolve the aging problem of pitch. And the invention uses the milling waste as material to avoid damaging the continuity of road, while the regenerated cold feeding material has high strength.

Description

technical field [0001] The invention relates to a road cold patching material, in particular to a regenerative road cold patching material used for quick repair of potholes on highways, municipal roads and other asphalt roads. Background technique [0002] With the rapid development of my country's economy, problems such as the rapid growth of traffic volume, large-scale vehicles, and serious overloading have been brought about, which make the asphalt concrete pavement face severe tests. The amount of pavement maintenance projects is increasing, and the requirements for maintenance technology are also increasing Higher and higher. At present, the filling materials used for the potholes on the road surface in actual construction are divided into hot material and cold filling material, and the hot material has the following disadvantages in use: (1) it cannot be used in low temperature winter and rainy season; (2) the pit The tank should be cleaned, drained of water and dried,...

Problems solved by technology

At present, the filling materials used for the potholes on the road surface in actual construction are divided into hot material and cold filling material, and the hot material has the following disadvantages in use: (1) it cannot be used in low temperature winter and rainy season; (2) the pit The tank should be cleaned, drained of water and dried, and then used after brushing the sticky layer of oil; (3) cannot be stored; (4) skilled workers and special machinery are required; (5) for small repair projects, the amount of material taken is more than The amount of materials used, the remaining materials are discarded, and the cost is high; (6) The traffic needs to be closed for a period of time after repairing; (7) The repair quality is not good, resulting in repeated repairs, wasting materials and labor costs, and more materials are required for insulation, resulting in waste

Cold patching material is a kind of pavement pothole filling material that is widely used at present, but the existing cold patching material has the following disadvantages in use: (1) All of them are made of new stone and new asphalt and then added according to a certain ratio It is made by mixing with replenishment liquid (cold repair additive), and the cost is relatively high; (2) it can only be used for repairing 2m 2 Potholes with the following area; (3) The repair quality is not good, resulting in repeated repairs, waste of materials and labor costs; (4) During use, it is found that the potholes have low strength and poor durability after repairing, and most of them are used no more than three times. Monthly, individual ones will fall off after only a few days of use, wasting a lot of raw materials, increasing the amount of work of the construction unit, and causing very large economic losses
