Problems solved by technology

[0004] However, at present, two major restrictive factors have been found in the application of micro-surfacing in my country, which have seriously affected the promotion of this technology: on the one hand, the micro-surfacing technology ignores the adhesion between the mixture and the original road surface in the process, due to the technical Defects and non-standard construction quality of the construction unit have seriously affected the durability of the micro-surfacing, and some road sections even have peeling, loose and other diseases within a few months after opening to traffic; on the other hand, the micro-surfacing In engineering practice, it is found that the "inside noise" in driving is significantly higher than that of hot-mixed and hot-paved asphalt pavement, which is 3 to 4 decibels higher than that of ordinary roads, which seriously affects driving comfort.

Abstract

The invention discloses an ultra-viscous fiber resin asphalt wearing layer mixture and a preparation method thereof. The ultra-viscous fiber resin asphalt wearing layer mixture is prepared from the following raw materials in parts by weight: 2 to 10 parts of bisphenol-a epoxy resin, 6.5 to 8.5 parts of asphalt, 90 to 110 parts of minerals, 0.5 to 1.5 parts of a filler, 0.1 to 1 part of water and 0.01 to 0.2 part of fibers. The preparation method of the ultra-viscous fiber resin asphalt wearing layer mixture comprises the following steps: (1) firstly preparing resin asphalt: heating the asphalt to be 120 to 150 DEG C, adding the heated asphalt into a mixture A in the bisphenol-a epoxy resin, stirring for 10 to 20 min, then mixing and stirring the mixture A with a mixture B, so as to obtain the resin asphalt; (2) adding the minerals, the filler, the water and the fibers according to parts by weight, and blending the asphalt mixture under low temperature. Compared with a conventional preventive pavement maintenance micro-surface treatment technology, an ultra-viscous fiber resin asphalt wearing layer prepared from the mixture has obvious advantages.

Description

technical field [0001] The invention relates to the field of highway maintenance, and relates to a superviscosity fiber resin asphalt wear layer mixture and a preparation method thereof. Background technique [0002] With the rapid development of road traffic in my country, expressways have gradually entered the peak period of maintenance, and the number of expressway and local road maintenance projects will be huge every year. Compared with corrective maintenance methods such as major and medium repairs, preventive maintenance technology, as an effective pavement maintenance method, can effectively reduce maintenance costs, delay pavement damage, and prolong road service life. [0003] At present, the commonly used preventive maintenance measures include not only cold-mix and cold-pave maintenance technologies such as fog seal, slurry seal, and micro-surfacing, but also hot-mix and thin-layer maintenance technologies such as ultra-thin wear layer (Novachip) and thin-layer o...
