Phases of Road Construction
(Preliminary Survey to Pouring Asphalt)
1. Preliminary Survey & Reconnaissance
- First inspection of the proposed road route
Engineers study:
• Terrain and topography
• Existing roads and settlements
• Drainage patterns
• Soil condition
• Environmental impact
- Survey equipment used:
• GPS
• Total Station
• Drone mapping
• Leveling instruments
- Purpose:
To identify the safest, shortest, and most economical alignment

2. Detailed Survey & Design
- Accurate measurements and mapping are carried out
Activities include:
• Centerline establishment
• Contour mapping
• Soil investigation
• Traffic studies
- Engineers and Surveyors prepare:
• Road geometry
• Cross-sections
• Pavement thickness design
• Drainage design
- Output:
Final construction drawings and BOQ (Bill of Quantities)

3. Site Clearing & Grubbing
Removal of:
• Trees
• Bushes
• Stumps
• Debris
• Existing weak materials
- Heavy equipment used:
• Bulldozers
• Excavators
• Chainsaws
- Purpose:
To prepare a clean and workable construction corridor

4. Earthwork & Excavation
- Cutting high ground and filling low areas
Activities include:
• Excavation
• Borrow pit filling
• Embankment formation
• Soil replacement
• Compaction begins gradually
- Machines used:
• Excavators
•Dump trucks
• Motor graders
• Rollers
- Goal:
To achieve the required road formation level

5. Subgrade Preparation
- Natural soil is shaped and compacted
Weak soils may be carted away or stabilized using:
• Cement
• Lime
• Laterite
- Tests conducted:
• Moisture content test
• CBR test
• Density test
- Importance:
The subgrade is the foundation of the entire pavement structure

6. Drainage Construction
Construction of:
• Side drains
• Culverts
• Channels
• Box culverts
- Prevents water from damaging the road
Poor drainage is one of the major causes of road failure

7. Sub-Base Layer Construction
First structural pavement layer above the
• subgrade
• Materials commonly used:
• Crushed stone
• Laterite
• Gravel
- Activities:
• Spreading
• Watering
• Grading
• Compaction
- Equipment used:
• Graders
• Water tankers
• Vibratory rollers
- Function:
Distributes traffic load evenly

8. Base Course Construction
- Strong load-bearing layer placed above the sub-base
Materials:
• Crushed aggregates
• Stone base
• Stabilized materials
- Requires high compaction and level accuracy
Importance:
Provides structural strength for heavy traffic loads

9. Prime Coat Application
- Bituinous liquid sprayed on the base layer
Purpose:
• Binds loose particles
• Improves adhesion between layers
• Reduces dust pe*******on
- Equipment used:
• Bitumen distributor/sprayer

10.Tack Coat Application
- Thin asphalt emulsion sprayed before asphalt laying
- Helps old and new asphalt layers bond properly
- Prevents layer separation and pavement cracks

11.Asphalt Production
- Asphalt materials are produced in an asphalt plant
Components mixed:
• Bitumen
• Sand
• Stone aggregates
• Filler materials
- Mixture is heated to the required temperature
- Quality control is very important at this stage

12. Asphalt Laying (Paving)
- Hot mix asphalt transported to site using dump trucks
- Asphalt paver spreads the material evenly
Workers monitor:
• Thickness
• Temperature
• Alignment
• Surface smoothness
Critical stage that determines required quality

13. Compaction of Asphalt
- Fresh asphalt is compacted immediately
• Rollers used:
• Steel drum rollers
• Pneumatic rollers
- Objectives:
• Remove air voids
• Increase strength
• Achieve smooth finish
Proper compaction improves road lifespan

14. Finishing & Quality Inspection
- Final checks conducted on:
• Surface level
• Slope
• Thickness
• Compaction
• Drainage efficiency
- Road markings and signs may be installed
- Defects are corrected before opening to traffic

Why Each Phase Matters
Every stage contributes to:
• Road durability
• Safety
• Smooth driving experience
• Reduced maintenance cost
- Skipping or poorly executing one phase can lead to:
• Cracks
• Potholes
• Settlement
• Early road failure

- Common Heavy Equipment Used
• Bulldozer
• Excavator
• Motor Grader
• Asphalt Paver
• Vibratory Roller
• Water Tanker
• Dump Truck
• Bitumen Sprayer
• Wheel Loader
