Abstract

The invention discloses a high-permeability penetrated oil layer for a semi-rigid road base layer, wherein the high-permeability penetrated oil layer is prepared from the following raw materials by weight: 400-600 parts of asphalt, 80-120 parts of kerosene, 10-20 parts of an emulsifier, 15-25 parts of hydrochloric acid, and 300-400 parts of water. The specific steps comprise: (1) heating the asphalt to a temperature of 120-140 DEG C; (2) mixing the kerosene, the emulsifier, the hydrochloric acid and the water, and heating to a temperature of 50-70 DEG C; and (3) simultaneously introducing theheated raw materials obtained in the step (1) and the step (2) into a colloid mill, and grinding to uniformly mix the raw materials so as to obtain the high-permeability penetrated oil layer. In the prior art, the domestic emulsified asphalt penetrated oil layer has poor permeability, the easily-formed oil film can be adhered away by the wheel, rolled or worn out, and other problems exist. According to the present invention, the high-permeability penetrated oil layer can solve the problems in the prior art; and through the auxiliary agent screening, formula optimizing and other system researches, the high-permeability penetrated oil layer is researched and developed and has advantages of safety, environment protection and good application effect.

Description

technical field [0001] The invention belongs to the technical field of road construction materials, and in particular relates to a high-permeability penetrating layer oil used for semi-rigid pavement bases and a preparation method thereof. Background technique [0002] The interlayer bond between the cement-stabilized macadam base and the asphalt pavement has always been a weak link of this type of pavement, which in turn leads to water damage of the base and deterioration of the stress state of the asphalt pavement. In order to solve this problem, 9.1 of "Technical Specifications for Construction of Highway Asphalt Pavement JTG F40-2004" stipulates that all kinds of bases must be sprayed with penetrating oil, and the penetration depth is required to be not less than 5mm, so as to play the role of consolidation, stability, connection and waterproof . [0003] At present, the penetrating oil products widely used in the market mainly include coal tar pitch, kerosene diluted p...
