“…Other countries like United Kingdom or Austria are following these directions, and their results have been growing around the 40% volume recycled. In the case of Mexico, small volumes of CDW are recycled, and more than the 85% of the material is sent to the landfills [19,20].…”

Materials play a fundamental role in any branch of civil engineering. From ancient times to the present day, society has required enormous amounts of construction materials, which implies an excessive exploitation of the natural environment. The present research work consisted in the design and development of asphalt mixes with a partial substitution of the natural aggregate (NA) by means of recycled concrete aggregate (RCA). The mix was designed with the Marshall methodology, considering the next percentages of substitution and addition by mass: 90% NA and 10% RCA; 80% NA and 20% RCA; 70% NA and 30% RCA. The mixtures were elaborated and analysed under the international standards and the Mexican regulation of the Communications and Transport Ministry, to determine the best option regarding their performance. The materials were characterized according to the current regulations and later employed in the mixes design. A total of 38 specimens were elaborated for each mixture, determining the optimum asphalt content; after that, mechanical tests were performed to analyse and determine the best results. In the aftermath of the examination of all mixtures, we concluded that the 70%AN/30%RCA is the best alternative option according to its performance and numeric results, complying with the cited regulations, and allowing a lower content of asphalt during the process.

The impact of RAP on water was identified to be analyzed for the material's resistance to water because there are still a lot of waterlogged pavements in Indonesia. This research uses RAP variation 0%, 25% and 35%. The test is the Marshall test to get the optimum asphalt content value, the Cantabro test to determine the weight loss for 300 rounds and the durability by varying the immersion 0.1, 2, 4 and 7 days which will be tested for ITS. The KAO value obtained for each variation is 5.4% for 0% Rap, 5.6 for 25% Rap and 6% for 35% RAP. The results of the Cantabro test show that the largest percentage of weight loss is a mixture of 35% RAP which is 12.54%, where for 0% RAP there is a weight loss of 10.85% and at 25% RAP there is a weight loss of 11.66%. ITS test results have the highest value with variations of RAP 0%, RAP 25% and RAP 35%. variations of 0%, 25% and 35% showed a decreasing trend until the 7th day of immersion, it can be said that in the three variations the ITS value was influenced by the duration of continuous immersion.

This article shows the results of the modulus of rupture test for concrete specimens added with PET fibers and also with polypropylene, with the objective of giving a second use to this waste through recycling, and its incorporation into concrete to improve its mechanical properties. The samples were tested with different fiber contents, and the results showed an increase in the modulus of rupture at 90 days with respect to a normal sample (1-3%). Specimens with PET and polypropylene fibers had a poor performance (<18%).
