Hot Mix Asphalt (HMA)
Properties: Produced at high temperatures, durable, provides smooth surface. Common Uses: Highways, airport runways, heavy-traffic roads.
Polymer-Modified Asphalt
Properties: Improved elasticity, higher resistance to deformation, better aging characteristics. Common Uses: High-stress pavements like intersections and bus lanes.
Sand
Properties: Fine granular material, compactable, fills small voids. Common Uses: Fine aggregate in asphalt and concrete, bedding layer for pavers.
Reclaimed Asphalt Pavement (RAP)
Properties: Recycled material, sustainable, reduced quality compared to virgin materials. Common Uses: Base/subbase layers, new asphalt mixtures.
Gravel
Properties: Rounded or angular particles, permeable, provides drainage. Common Uses: Unpaved roads, subbase layers, aggregate in asphalt and concrete.
Mastic Asphalt
Properties: Waterproof, durable, seamless. Common Uses: Bridge decking, footpaths, flat roofs.
Aggregates
Properties: Varied size and composition, high strength, provides bulk. Common Uses: Component of asphalt and concrete, road base layers.
Pervious Concrete
Properties: Porous, allows water to pass through, reduces runoff. Common Uses: Parking lots, sidewalks, green infrastructure for stormwater management.
Porous Asphalt
Properties: Open-graded, allows water to drain through, minimizes runoff. Common Uses: Parking lots, driveways, sustainable urban drainage systems.
Concrete
Properties: High compressive strength, brittle, low tensile strength. Common Uses: Highways, bridges, parking lots.
Asphalt
Properties: Adhesive, waterproof, flexible when hot. Common Uses: Road surfaces, roofing, waterproofing.
Crushed Stone
Properties: Angular shape, various sizes, high strength. Common Uses: Base material for pavements, drainage applications.
Portland Cement
Properties: Hydraulic cement, hardens when mixed with water, good compressive strength. Common Uses: Binder in concrete production.
Glassphalt
Properties: Contains recycled glass, similar performance to traditional asphalt. Common Uses: Pavements, reduces landfill waste.
Rubberized Asphalt
Properties: Contains recycled tire rubber, noise-reducing, mitigates cracking. Common Uses: High traffic roads, reduces road noise, and improves durability.
Subbase Course
Properties: Lower quality aggregates, serves as a stable foundation. Common Uses: Layer beneath the base course, provides stability and drainage.
Warm Mix Asphalt (WMA)
Properties: Produced at lower temperatures, energy-efficient, reduced emissions. Common Uses: Pavements with similar performance to HMA.
Chip Seal
Properties: Layer of asphalt emulsion followed by aggregate chips. Common Uses: Surface treatment, provides skid resistance, extends pavement life.
Fiber-Reinforced Concrete
Properties: Contains fibrous material, increased tensile strength, reduces cracking. Common Uses: Overlays, bridge decks, joint-less pavements.
Geotextiles
Properties: Synthetic fibers, permeable, enhances soil strength. Common Uses: Soil reinforcement, filtration, separation layers beneath pavements.
Cold Mix Asphalt
Properties: Applied at ambient temperatures, maintains workability for longer periods. Common Uses: Temporary patching material, low-traffic roads, emergency repairs.
Base Course
Properties: High quality aggregates, compactable, bears structural loads. Common Uses: Sub-layer for asphalt and concrete pavements, supports surface layer.
Bitumen
Properties: Highly viscous, black, sticky. Common Uses: Binder in asphalt concrete, road construction, waterproofing.
Steel
Properties: High tensile strength, ductility, recyclable. Common Uses: Reinforcement in concrete, bridge structures, guardrails.
Tire-Derived Aggregate (TDA)
Properties: Made from shredded tires, lightweight, provides good drainage. Common Uses: Subbase for roadways, backfill material, landfill projects.
