The present research aims to control the usual phenomenon of plastic shrinkage cracking in 280kg/cm2 rigid pavement by adding 5 cm long fibers of recycled wire No. 16. Cracks in newly placed concrete slabs, caused by rapid water loss due to environmental factors such as high temperatures, high wind speed and low humidity, affect their appearance and can reduce the service life of the structure if not treated in time. This research has an explanatory research level and experimental design. The population for the evaluation of cracks was 19.2m2 and samples of 4 concrete slabs of 4.8m2 each with a uniform thickness of 0.15m, applying the direct observation technique using an observation sheet as an instrument. In addition, the workability, compressive strength, flexural strength and unit price analysis were evaluated for the different samples with additions of 10, 15 and 20 kg/m3 of recycled wire No. 16. The most favorable results are including 20 kg/m3 of this fiber, evidencing a crack reduction ratio (CRR) of 58. 7%, reductions of 70% in crack incidence, 35.2% in average length, 59.6% in average width, 92% in total affected area and 75.56% in average crack area compared to the commercial steel fiber reinforced concrete slab CHO 65/35 NB at a ratio of 20 kg/m3. It was determined that the additions of 15 and 20 kg/m3 of No. 16 recycled wire fiber had superior control of plastic shrinkage cracking compared to the use of commercial steel fiber.
