The invention discloses a method for testing acid-corrosion resistance of road concrete. The method comprises the steps of splashing a saltpeter solution with 30% of mass percent content on cement to be tested at the 4-6-hour intervals, blowing the cement to be dry at the air speed 20-30 km/h, repeating the operation for 8-12 days, and counting the number of cement speckles. The method has the advantages that according to the method for testing the acid-corrosion resistance of the road concrete, the operation process is simple, the accuracy degree is high, the concrete corrosion conditions in the natural environment are simulated completely, through the validation, the similarity rate with the concrete corrosion effect in the natural environment is as high as over 80%, and the method can serve as the standard for testing the corrosion resistance of the concrete.
