Problems solved by technology

Compared with hot mix asphalt mixture, cold patching material has the following advantages: (1) It is not limited by climatic conditions, and can be constructed in low temperature winter and rainy season; (2) The pits do not need special treatment such as painting sticky oil; (3) No special construction personnel and equipment are required; (4) easy to store and can be taken out at any time without causing material waste; (5) traffic can be opened immediately after repairing; but the existing cold patching materials also have the following disadvantages: ( 1) The durability is not good, and most pits will peel off or be damaged in a short time after using cold patching materials; (2) At present, most of the cold patching asphalt mixtures use new stone and new matrix asphalt, and the The cost of adding cold patching additives to the patching material is relatively high; (3) Most of the cold patching material only repairs 2m 2 The following potholes, the repair area is small
The CN101008172B patent uses milling waste, which has the advantages of greatly improving the anti-rutting performance of the recycled road cold patching material and greatly increasing the repair area, but there are also the following disadvantages: (1) Only the recycled road milling waste, There is no composite recycling of waste rubber powder, and the regeneration efficiency is low; (2) Most of the asphalt in the road milling waste has been aged, so the cohesive performance and water resistance of the recycled road cold patching material are reduced; (3) Low temperature operation ease of performance

Embodiment 1

[0037] 1. Material preparation:

[0038] Diesel: use ordinary 0 # diesel fuel.

[0039] Base asphalt: Grade A 70# road petroleum asphalt is used, and the asphalt produced by CNOOC Taizhou Plant is used in this example.

[0040] Waste rubber powder: waste truck tires with high natural rubber content were used and obtained by shearing and crushing. The particle size of the waste rubber powder used in this example was 40 mesh.

[0041] Asphalt road milling waste: Beijing-Shanghai high-speed surface layer milling waste is used. Before use, the milling material needs to be sieved to remove larger agglomerated milling materials. The particle size of the milling material after sieving is: 3-16mm.

[0042] Mineral powder: Mineral powder processed from limestone is required. The particle size requirement is that the pass rate of 0.6mm sieve hole is 100%, the pass rate of 0.15mm sieve hole is greater than 90%, and the pass rate of 0.075mm sieve hole is greater than 75%.

Description

technical field [0001] The invention relates to a waste rubber powder composite regeneration all-weather road cold repair material and its production method, especially to a waste rubber powder and asphalt road milling waste regeneration cold repair material and its production method, belonging to waste recycling and cold repair Supplementary material production method technical field. Background technique [0002] With the rapid development of road transportation, the number of automobiles has increased significantly, and more and more waste tires are produced every year, which has become an environmental problem that needs to be solved urgently. At the same time, a large amount of waste materials will be generated in the process of asphalt pavement maintenance, repair and transformation. If these waste materials are not utilized, they will occupy a large amount of land and pollute the environment. [0003] Asphalt roads are prone to potholes and other diseases under the a...
