Abstract

This invention relates to a panel dreg-free emulsified asphalt-cement mortar used in orbits, its manufacturing method and an application including cement, mixed materials, emulsified asphalt, sand, water, polymer latex, defoaming agent, Al powder, an air entrainer and a regulator, which solves the problem of short working time, poor adaptability to temperature, easy separation, hard expansion after 24 hours of injection of the present emulsified asphalt-cement mortar and provides a panel dreg-free emulsified asphalt-cement mortar working long, well suitable to temperature, hard separated, easily expanding, low cost and raw materials are got easily.

Description

technical field [0001] The invention relates to the field of building materials, and relates to an emulsified asphalt cement mortar for a slab ballastless track and a manufacturing method and application thereof. Background technique [0002] The slab ballastless track is one of the important structural forms of the railway or urban light rail ballastless track. It is the most mature technology in the world. It is characterized by laying a concrete base on the roadbed and placing a prefabricated track slab on the base. Reserve a gap of 3 to 5 cm, pour emulsified asphalt cement mortar, and form a uniform filling cushion with both rigidity and elasticity after curing. Emulsified asphalt cement mortar is a key component of the elastic adjustment layer of railway or urban light rail ballastless track structure. At present, it is still in the stage of experimental development in China, and there is no product with excellent performance. Although the Chinese patent ZL02139237.4 d...
