The pavement inspection process is of utmost importance to know its condition and thus make decisions regarding its conservation and maintenance. This research proposes a methodology to optimize the pavement inspection process based on the ASTM D6433 standard through the use of drones and the Cascade Trainer algorithm. Images of pavement pathologies were used to train the algorithm and with it they will carry out the pavement inspection in the videos captured by the DJI mini 4 pro drone. The algorithm demonstrated high performance with an average accuracy of 96%, a cost reduction of 77% compared to the “American Society for Testing and Materials” Method (ASTM D6433) and a performance capable of measuring 600 more meters per workday. Finally, the results of this research can be useful to promote a proposal for improvement in the inspection of flexible pavements for their conservation through automated and high-precision methods

Accessible road design must meet the needs of people with reduced mobility (PRM), who face significant obstacles in BRT stations due to inadequate infrastructure. Although some improvements, such as ramps and signage, have been implemented, barriers still persist, particularly for older adults and individuals with visual or motor impairments. This study focuses on improving the infrastructure of the Naranjal station of the Metropolitano, considering accessibility, travel times, pedestrian density, and safety. Tools such as VISSIM and StatKey were used to validate simulations and model pedestrian flows with high precision. The proposals include a strategically placed new ramp, exclusive access points with appropriate signage, and the creation of a refuge island. The results demonstrate an average reduction in conflicts of 88.32%, a 22.75% decrease in travel times, and an improvement in the level of service, reaching category A in some areas.

The objective of this study was to develop ecological mortars incorporating construction and demolition waste (CDW) and crushed plastic as substitutes for traditional materials, evaluating their technical and economic viability. Various tests were carried out to characterize the waste, including granulometry, unit weight, moisture content and specific gravity, obtaining results within the parameters established for the mixture of mortars. Then, a total of 24 mortars were prepared, of which 6 standard mortars and 6 for each of the replacement of 5%, 10% and 15% of waste by crushed plastic. Then the manufacturing process of the mortars began and they were left in formwork for 24 hours, then they were stripped and the curing process began in a period of 3 and 7 days respectively, then the resistance tests were carried out. And finally, it was determined that the mortars cured in 7 days obtained a higher resistance test compared to those cured in three days.. The mortars with 10% plastic showed a noticeable superior resistance, standing out as a viable alternative. This viable alternative seeks to reduce and eliminate contaminants, such as plastic being one of the main ones, thus making this implementation a possible solution to this problem.

The aim of this research is to select a material with low environmental impact, easily obtainable in rural areas, and cost-effective, to improve the mechanical properties of adobe. Because of this, it is necessary to determine the compressive strength of stabilized adobe by incorporating coal ash and eucalyptus wood sawdust in different percentages. The research was experimental and carried out at the Universidad Privada del Norte, 60 units of adobe blocks were made on the Cinva Ram machine classified into 5 types, conventional adobes, adobe plus 2% and 3% coal ash and adobes plus 3% and 5% wood sawdust. Subsequently, they were tested at the age of 28 days on the compressive strength machine where the following data were obtained, for conventional adobe 38.57 kg/cm2, adobe plus 2% and 3% coal ash with values of 55.45 kg/cm2 and 25.93 kg/cm2 respectively, and for adobe plus 3% and 5% of wood sawdust, 25.76 kg/cm2 and 25.90 kg/cm2 were obtained, respectively. It is concluded that the addition of 3% coal ash to conventional adobe increases compressive strength by 43.76% compared to conventional adobe.

The purpose of the research is the incorporation of a recycled material that allows to increase the resistance properties of the concrete and its influence in the reduction of the thickness of the rigid pavement obtained with the design values of the project "Optimization of the Section of the Old Pan-American Highway South, Section: Arica - Santa María del Mar; Areas: Lurín, Puntas Hermosa and Negra, San Bartolo and Santa María del Mar, Province of Lima - Lima", completed in 2019.

For this reason, through a quantitative method, by means of pure experimental design, applying laboratory tests, the Can Fiber (CF) was used in proportions of 0%, 0.25%, 0.50%, 0.75 and 1% respect to the weight of the cement, incorporated into the design of the mixture of resistance f'c = 420 kg / cm2 and Modulus of Rupture (MR) of 48 kg / cm2 with a pavement thickness of 27 cm.

50 cylindrical specimens were analyzed for the f'c and 50 beams for the MR, 10 samples for each percentage of FL, concluding that the incorporation of recycled can fiber increases the f'c and MR resistance properties at 28 days, with a reduction in the thickness of the rigid pavement up to 6.29% with FL at 1%, however, other studies are warranted to verify the cost benefit of implementing this method.
