2.Scope

Thisconstructionplanfocusesspecificallyonthesubgradeconstructionforthepavement.Itprovidesguidelinesforthepreparationofsubgrade,includingexcavation,compaction,andstabilization.Theplanalsoincludestheselectionandapplicationofsuitablematerialsandtechniquestoensurethestabilityandstrengthofthesubgrade.Itisessentialtoadheretothisplantoachievethedesiredqualityanddurabilityoftheroad.

3.SubgradeConstructionProcedure

Thesubgradeconstructionprocedureconsistsofthefollowingsteps:

3.1Excavation

Thefirststepinsubgradeconstructionisexcavation.Theexcavationareashouldbemarkedandclearedofanyobstacles.Excavationisperformedtoremoveunsuitablematerialsandcreateastablefoundationfortheroad.Thedepthofexcavationshouldbeasperthedesignspecificationsandrequirements.

3.2Compaction

Afterexcavation,thesubgradeshouldbecompactedtoachievetherequireddensity.Compactionisessentialforimprovingsoilstability,reducingsettlement,andincreasingload-bearingcapacity.Suitablecompactionequipmentshouldbeused,andthecompactionprocessshouldbecarriedoutinlayerstoachieveuniformdensity.

3.3Stabilization

Insomecases,subgradestabilizationisnecessarytoenhancethestrengthandstabilityofthesubgrade.Stabilizationcanbeachievedthroughdifferentmethods,suchasaddingstabilizingagents,likelimeorcement,orusinggeosyntheticmaterials.Theselectionofthestabilizationmethodshouldbebasedonthesoilpropertiesandsiteconditions.

3.4MoistureControl

Moisturecontroliscrucialduringsubgradeconstructiontopreventexcessivemoisturecontent.Excessmoisturecanleadtosoilinstabilityandpoorcompaction.Properdrnagemeasuresshouldbeimplementedtoremoveexcesswaterandmntntheoptimalmoisturecontentinthesubgrade.

3.5QualityControl

Qualitycontrolshouldbeimplementedthroughoutthesubgradeconstructionprocesstoensurecompliancewiththedesignspecificationsandrequirements.Regulartestingshouldbeconductedtoassessthecompactiondensity,moisturecontent,andstabilityofthesubgrade.Anydeviationsfromthespecifiedparametersshouldbepromptlyaddressed.

4.MaterialsandEquipment

Theselectionofmaterialsandequipmentforsubgradeconstructionisessentialtoachievethedesiredresults.Thefollowingshouldbeconsidered:

4.1Materials

Suitablefillmaterials,suchasgravelorcrushedstone,shouldbeusedforsubgradepreparation.

Stabilizingagents,likelimeorcement,canbeusedtoenhancethestrengthandstabilityofthesubgrade.

Geosyntheticmaterialscanbeemployedforsubgradestabilizationifrequired.

4.2Equipment

Excavators,bulldozers,orgradersareusedforexcavation.

Compactionequipment,suchasvibratoryrollersorcompactors,shouldbeusedforsubgradecompaction.

Testingequipment,likemoisturemetersanddensitygauges,areessentialforqualitycontrol.
