Problems solved by technology

Ordinary micro-surfacing technology, due to the limitations of the construction materials used and the defects of the treatment process, has the following problems: the noise inside the vehicle is significantly higher than that of the hot-mixed and hot-paved asphalt pavement, resulting in traffic noise pollution, which seriously affects the performance of drivers and passengers in the vehicle. The driving comfort of personnel, according to research: rubber powder particles can absorb noise, but if rubber powder is added to emulsified asphalt by general methods and formulas, rubber powder will float up, and small pieces of rubber powder will also peel off when paved on the road surface The phenomenon

Abstract

The invention discloses a mixing-type rubber powder modified emulsified asphalt and a preparation method thereof. The preparation method comprises the following steps: mixing an A material and a B material, wherein the A material accounts for 60 to 70% of the total weight of the A material and B material and the B material accounts for 30% to 40% of the total weight of the A material and B material; and then mixing the prepared modified emulsified asphalt with a C material according to a weight ratio of 85-90%:10-15% so as to obtain the mixing-type rubber powder modified emulsified asphalt; wherein the A material is composed of the following raw materials in parts by weight: 100 parts of asphalt; the B material is composed of the following raw materials in parts by weight: 2 to 2.5 parts of octadecanamido sodium diphenyl ether disulfonate, 95.5 to 97 parts of water, and 1 to 2 parts of cation neoprene latex; and the C material is composed of the following raw materials in parts by weight: 95 to 98 parts of tire rubber powder and 2 to 5 parts of tall oil. The mixing-type rubber powder modified emulsified asphalt has a strong bond stress; and has the advantages of low production cost, and simple production technology. Furthermore, tire rubber powder is added to reduce the noise during the driving process, the service life of micro-surfacing is prolonged too, thus the maintenance is reduced at the same time, and the tire rubber powder is evenly dispersed and does not float upward.

Description

technical field [0001] The invention belongs to the technical field of road engineering, and in particular relates to a mixing type rubber powder modified emulsified asphalt used in the micro-surface treatment process of roads, which can not only maintain the micro-surface function but also effectively reduce driving noise and its preparation method . [0002] Background technique: [0003] Microsurfacing can complete multiple repair functions such as pavement structure repair, crack sealing, and rut filling; compared with hot asphalt thin-layer overlay, it has the advantages of fast and efficient construction, and saves road maintenance and repair costs; under the premise that the roadbed and pavement are in good condition , The service life of the micro-surface can be as long as more than 3 years. Ordinary micro-surfacing technology, due to the limitations of the construction materials used and the defects of the treatment process, has the following problems: the noise in...
