The invention relates to the technical field of restraining of an asphalt volatile organic compound, in particular to an asphalt volatile organic compound composite inhibitor, smoke-restraining asphalt, a manufacturing method of the asphalt volatile organic compound composite inhibitor and a manufacturing method of the smoke-restraining asphalt. The composite inhibitor is prepared from the following components in parts by weight: 3-7 parts of an SBS modifying agent, 1.5-5 parts of activated carbon, and 1.5-6 parts of magnalium-based layered double-hydroxyl composite metal hydroxide. The smoke-restraining asphalt is prepared from the following components in parts by weight: 87-90 parts of substrate asphalt, 4-5 parts of an SBS modifying agent, 2-4 parts of activated carbon, and 2-4 parts of magnalium-based layered double-hydroxyl composite metal hydroxide. The manufacturing method of the smoke-restraining asphalt comprises the following steps: heating the substrate asphalt to 150-170 DEG C and performing stirring in a heat insulating manner; in the stirring process, sequentially adding the SBS modifying agent, the activated carbon and the magnalium-based layered double-hydroxyl composite metal hydroxide to the substrate asphalt; after performing stirring, performing cutting. The asphalt in which the composite inhibitor is added is better in gas released effect than the smoke-retraining asphalt modified by other inhibitors, so that VOC release amount of the asphalt is greatly reduced.
