Experimental evaluation of the usability of palm tree pruning waste (PTPW) as an alternative to geotextile

Abstract

This paper focuses on serving twofold benefits for the environment by providing not only recycling of a waste material but also improving rutting performance of sand subgrade under cyclic traffic loads. In this context, a series of laboratory experiments have been conducted to benchmark the performance of commercially manufactured geotextile and palm tree pruning waste (PTPW) as soil improvement agents. Experimental results of the study were evaluated based on permanent (plastic), total, and elastic deformation, rut depth reduction (RDR), traffic benefit ratio (TBR), percentage of elastic deformation, and resilient modulus (MR). In the view of experimental results, geotextile and PTPW-reinforced sand subgrades demonstrated well performance in the sense of permanent and elastic deformations when compared to unreinforced case. It is also realized that the most satisfactory performance was obtained when geotextile or PTPW are located at a burial depth of both 50 mm and 100 mm. In that case, TBR values of geotextile and PTPW-reinforced subgrades were almost the same at 20 mm permanent deformation (i.e., 6.71 and 6.76, respectively). Furthermore, when the results were evaluated based on RDR, it is observed that geotextile and PTPW reinforcements reduced the rut depth at the rate of 49.31 % and 37.15 % at the end of 5000 load cycle, respectively.

Comparative effectiveness research of palm tree pruning waste and geotextiles on subgrade stabilization

“…In this study, two types of relative densities (loose and dense) were evaluated. Note that previous studies have also addressed similar relative densities [48][49][50].…”

“…Previously, experimental studies have been typically conducted using a single type of subgrade material [20,[47][48][49]; this subgrade material can have several different relative densities.…”

Evaluación físico-mecánica de las mezclas asfálticas mediante la adición de aceite reciclado de motor

“…Por lo dicho líneas arriba y teniendo en cuenta que el aceite quemado es un agente altamente contaminante (pues un litro de dicho elemento contamina hasta un millón de litros de agua), se considera que al utilizarlo en una mezcla asfáltica se brinda beneficio doble para el medio ambiente al proporcionar, no solo el reciclaje de dicho material contaminante; sino mejorar el rendimiento y la vida útil del pavimento flexible (Kaplan, Kayadelen, Ozturk y Oñal, 2022). Por todo esto, el presente estudio tiene como objetivo estudiar un nuevo diseño de mezcla asfáltica en caliente y evaluar sus propiedades fisico-mecanicas al adicionar aceite reciclado de motor (ARM), así como fomentar la reutilización de agentes contaminantes del medio ambiente como es el ARM.…”

Soil stabilization using rice husk ash and cement for pavement subgrade materials

“…Numerous methods for improving soil stabilization in the construction area include geotextile reinforcement and pozzolanic reinforcement. Several successful techniques for utilizing pozzolanic materials, such as Portland cement, lime, and fly ash, have been developed (Aziz et al, 2015;Kaplan et al, 2022;Kishor et al, 2022;Nguyen et al, 2020;Suksiripattanapong et al, 2017). This existing method proves that stabilizing the soil using pozzolanic material can increase the carrying capacity of the soil itself.…”
