Abstract - Due to weak subgrade soils, steep slopes, high rainfallintensity,andfrequentslopefailuresroadconstruction inlandslide-pronehillyareasisamajorengineeringchallenge. Conventional or traditional road pavement system are often expensive, time consuming and very difficult to maintain in such areas. This review paper examines the influence of Geocells High-Density Polyethylene (HDPE) material reinforcedinroadpavementconstructionforlandslide-prone areas,emphasizingtheuseofecofriendlyandlocallyavailable material. Geocells road pavement system provides a threedimensionalconfinementtofillwithmaterialsuchaslocalsoil and aggregate, improves in load distribution, shear strength and erosion control while minimizing environmental impact and maintenance requirements. The methodology integrates geocell technology with eco-friendly materials to reduce construction costs by up to 10-80%, decrease construction time, and enable community-based maintenance. This study highlights construction methodology, advantages, cost effectiveness, ease of maintenance, and suitability for rural and remote areas. Geocells reinforced pavement system is a viable and low-cost solution for landslide regions.

1. INTRODUCTION

Road infrastructure in mountainous and hilly regions is highly vulnerable to landslides due to steep terrain, weak subgrade soils, and heavy rainfall. These conditions often leadtopavementdistress,slopefailures,trafficdisruption, and increased maintenance costs, severely affecting connectivityinrural andremoteareas.Conventional road constructionmethodsrequireheavymachinery,high-quality materials,andskilledlabour,makingthemexpensive,timeconsuming,andunsuitableforlandslide-pronelocations. In this context, geosynthetic-based solutions offer a sustainablealternativeforroadconstruction.Amongthem, geocell-reinforced systems made from High-Density Polyethylene (HDPE) provide an effectivee means of improvingpavementperformanceoverweaksoils.Geocells formathree-dimensionalhoneycombstructurethatconfines

1.1 GEOCELLS

Geocells are three-dimensional honeycomb-like cellular confinementsystemsmadefrompolymericmaterials(mainly HDPE).

Whenexpandedandfilledwithsoil,sand,gravel,orconcrete, they create a strong composite structure that improves load-bearingcapacityandreducessoilmovement. Theyarewidelyusedin:

3. Methodology

The study was carried out to evaluate the effectiveness of geocell reinforcement for stabilizing roads and slopes in landslide-prone areas. Initially, a literature review was conducted to understand weak subgrade behaviour and geocellreinforcementmechanisms.Basedonthis,suitable materialssuchasHDPEgeocellsandlocallyavailableinfill materialswereselected.Laboratorytestswereperformedto determinethepropertiesofthesubgradesoil.

Modelsectionswithandwithoutgeocellreinforcementwere prepared for comparison. Geocells were placed over the prepared subgrade, filled with soil or aggregate, and properly compacted. Drainage and surface protection measures were provided to simulate field conditions. Repeatedloadingtestswerethenapplied,andparameters suchassettlement,rutting,anddeformationwereobserved. Theperformanceofreinforcedsectionswascomparedwith unreinforcedsectionstoassessimprovementsinstrength, stability,anddurability.

Two road models will be prepared: a conventional (unreinforced) road and a geocell-reinforced road. Both modelswillbeconstructedusingthesamesubgradesoiland pavementlayersforuniformcomparison.Inthereinforced model,geocellswillbeplacedoverthesubgrade,filledwith locally available soil or aggregate, and compacted.
