To combat permanent deformation in flexible road pavements and extend lifespan while reducing maintenance costs, an investigated solution "Corrugated Geogrid and Geocell Reinforced Flexible Pavement Base Design" is proposed. It enhances durability by improving inter-layer bonding and increasing the friction coefficient with a Corrugated Imminent Hexagonal Composite Geogrid, boosting pavement bearing capacity. The necessity of this research is the integration of corrugated geogrids and geocells into the design of flexible pavement, in conjunction with a comprehensive evaluation of interlayer shear performance, effectively tackles a range of engineering obstacles and enhances the pavement system's durability, stability, and affordability. Geogrid's corrugated structure resists shoving, offers stabilization, and, combined with Fusion Geoblanket and Perforated Geocell, prevents potholes. Typically, geocellular brace parts are utilized in civil engineering and technical applications, and they are frequently connected to geocellular systems or geocells. These systems are frequently employed in the building of retaining walls, slope protection, erosion control, and soil stabilization. The intended use and product design influence the installation procedures and specific functioning approach. The proposed model prevents permanent pavement failures, ensuring durability, low maintenance, and improved lifespan, assessed through Finite Element Analysis. Thus, the proposed method develops a layout for flexible pavement that's going to prolong its life expectancy and prevent long-term deformation failure.

“…The most common methods for repairing cracks in asphalt pavement are pouring, sealing, and digging-patching, using materials such as modified asphalt and resin [8,9]. For pothole repair, traditional methods involve removing old material and filling with new material, using either hot-mixed or cold-mixed asphalt mixture [10]. These maintenance methods often require multiple workers and can be time-consuming and risky, especially in areas with heavy traffic [11].…”

To examine the application and significance of 3D printing technology in pavement maintenance engineering, a review of the current developments in principles, types, materials, and equipment for 3D printing was conducted. A comparison and analysis of traditional methods and 3D printing for asphalt pavement maintenance led to an investigation of 3D asphalt printing technologies and equipment. As a result, the following suggestions and conclusions are proposed: 3D printing technology can increase the level of automation and standardization of pavement maintenance engineering, leading to effective improvements in worker safety, climate adaptability, repair accuracy, etc. For on-site repair of cracks and minor potholes, utilizing material extrusion technology a mobile 3D asphalt printing robot with a screw extrusion device can be used for accuracy and flexibility. For efficient repair of varying cracks, material jetting technology with a UAV equipped with a 3D printing air-feeding device can be employed.

“…Aquellas fallas son el resultado del daño por humedad, la calidad del asfalto, el espesor de la estructura del pavimento y la adhesión existente entre el asfalto y el agregado [9], [10]. En ese orden de ideas, el deterioro superficial presentado en el pavimento puede ser ocasionado por inapropiados procesos constructivos como: baja y/o inadecuada compactación, baja adhesión entre los materiales, desprendimiento, degradación, fisuración, envejecimiento del cemento asfáltico, exceso de cargas de tráfico para el que fue diseñado, deformación permanente o fatiga mecánica producida en el material asfáltico [3], [9], [12], [13].…”

El objetivo de este trabajo es determinar el periodo de desempeño de tres mezclas asfálticas prefabricadas utilizadas para actividades de parcheo en pavimento flexible. Los materiales se evaluaron por ensayos de granulometría, gravedad específica bulk, gravedad específica máxima. Por su parte, el desempeño de las mezclas se evaluó a través de ensayos de estabilidad y flujo, ensayos de Cántabro y ahuellamiento, módulo resiliente, fatiga trapezoidal y evaluación de la susceptibilidad al agua por tracción indirecta (TSR). Conforme a los resultados para la mezcla I, se concluye que este material no es recomendable para su uso, ya que presentó un comportamiento desfavorable durante y después de los ensayos de laboratorio. Para las mezclas tipo II y III, se determinó la evaluación del número de ejes equivalentes mediante las metodologías empírico mecanicista francesa y la AASTHO-93. Producto de la modelación, se evidenció que las mezclas soportaron tráficos bajos clasificados entre T1 y T2, con un periodo de desempeño para la mezcla tipo II entre cinco y seis meses, y para la mezcla tipo III entre uno y quince meses. Resultados obtenidos según metodología evaluada. Se concluyó que las mezclas tipo II y III son mezclas adecuadas para realizar intervenciones por emergencia en corredores viales que soportan tráficos bajos.
