The invention discloses a theoretical calculation method for the water content of a mixed material of a cement stabilized macadam road pavement, and aims to determine an optimal water content of the mixed material of the cement stabilized macadam road pavement, and the optimal water content of the mixed material can be relatively precisely and reasonably determined with comparison with an indoor testing result. The theoretical calculation method comprises the following steps: performing theoretical calculation on the standard water rate of cement in a test part used in an indoor test, the water absorption rate of an aggregate and the water rate of a middle gap of the mixed material, converting calculated results into the water amount of the cement in the test part, the water absorption amount of the aggregate and the water amount of the middle gap of the mixed material so as to determine an actual optimal water amount of the mixed material, and further converting the optimal water amount of the mixed material into the optimal water content of the mixed material. By adopting the theoretical calculation method, the situation that the optimal water content of the mixed material can be only determined by using an indoor testing method can be changed, the proportioning rate of the water content of the mixed material of the cement stabilized macadam road pavement can be relatively and reasonably designed, the construction quality can be improved, rework can be avoided, and the production cost can be lowered.
