The invention relates to a construction process for constructing a high-filling highway embankment by red-layer mudstone. The construction process comprises the following steps: S1, cleaning a cleaning a constructed pavement; s2, pretreatment: spraying water to the red-layer mudstone, wherein the red-layer mudstone absorbs water, expands and disintegrates; s3, layered filling: carrying out layered filling on the construction area embankment; s4, uniform loose laying is conducted, specifically, each layer of red layer mudstone is subjected to uniform loose laying; s5, impact type rolling is conducted, specifically, each layer of red layer mudstone is subjected to impact compaction through an impact rolling wheel; s6, compaction is conducted, specifically, the red-layer mudstone is compacted in a common compaction mode and a dynamic compaction mode; and S7, quality detection is conducted, specifically, tracking detection is conducted on each layer of red-layer mudstone, then reinspection is conducted, sampling
