The invention relates to a light grouting material for grouting treatment of a highway goaf and a preparation method of the light grouting material. An existing under-highway goaf grouting treatment technology has the defects of being high in grout water content and large in unit weight. Cement, coal ash and water are mixed and evenly stirred to obtain cement and coal ash slurry; a negative and positive zwitter ion surface active agent is added to water to be evenly stirred to obtain a surface active agent solution, a stabilizer is added to the surface active agent solution to obtain a negative and positive zwitter surface active agent compound foaming agent solution; cement and coal ash slurry is doped with the negative and positive zwitter surface active agent compound foaming agent solution to be stirred to obtain the light grouting material. The prepared light grouting material is small in stone body density, large in intensity, good in construction performance, little in grouting and much in filling, and capable of overcoming the defects of the prior art.
