Hot Mix Asphalt (HMA)

StarStarStarStar

Properties: Produced at high temperatures, durable, provides smooth surface. Common Uses: Highways, airport runways, heavy-traffic roads.

StarStarStarStar

Polymer-Modified Asphalt

StarStarStarStar

Properties: Improved elasticity, higher resistance to deformation, better aging characteristics. Common Uses: High-stress pavements like intersections and bus lanes.

StarStarStarStar

Sand

StarStarStarStar

Properties: Fine granular material, compactable, fills small voids. Common Uses: Fine aggregate in asphalt and concrete, bedding layer for pavers.

StarStarStarStar

Reclaimed Asphalt Pavement (RAP)

StarStarStarStar

Properties: Recycled material, sustainable, reduced quality compared to virgin materials. Common Uses: Base/subbase layers, new asphalt mixtures.

StarStarStarStar

Gravel

StarStarStarStar

Properties: Rounded or angular particles, permeable, provides drainage. Common Uses: Unpaved roads, subbase layers, aggregate in asphalt and concrete.

StarStarStarStar

Mastic Asphalt

StarStarStarStar

Properties: Waterproof, durable, seamless. Common Uses: Bridge decking, footpaths, flat roofs.

StarStarStarStar

Aggregates

StarStarStarStar

Properties: Varied size and composition, high strength, provides bulk. Common Uses: Component of asphalt and concrete, road base layers.

StarStarStarStar

Pervious Concrete

StarStarStarStar

Properties: Porous, allows water to pass through, reduces runoff. Common Uses: Parking lots, sidewalks, green infrastructure for stormwater management.

StarStarStarStar

Porous Asphalt

StarStarStarStar

Properties: Open-graded, allows water to drain through, minimizes runoff. Common Uses: Parking lots, driveways, sustainable urban drainage systems.

StarStarStarStar

Concrete

StarStarStarStar

Properties: High compressive strength, brittle, low tensile strength. Common Uses: Highways, bridges, parking lots.

StarStarStarStar

Asphalt

StarStarStarStar

Properties: Adhesive, waterproof, flexible when hot. Common Uses: Road surfaces, roofing, waterproofing.

StarStarStarStar

Crushed Stone

StarStarStarStar

Properties: Angular shape, various sizes, high strength. Common Uses: Base material for pavements, drainage applications.

StarStarStarStar

Portland Cement

StarStarStarStar

Properties: Hydraulic cement, hardens when mixed with water, good compressive strength. Common Uses: Binder in concrete production.

StarStarStarStar

Glassphalt

StarStarStarStar

Properties: Contains recycled glass, similar performance to traditional asphalt. Common Uses: Pavements, reduces landfill waste.

StarStarStarStar

Rubberized Asphalt

StarStarStarStar

Properties: Contains recycled tire rubber, noise-reducing, mitigates cracking. Common Uses: High traffic roads, reduces road noise, and improves durability.

StarStarStarStar

Subbase Course

StarStarStarStar

Properties: Lower quality aggregates, serves as a stable foundation. Common Uses: Layer beneath the base course, provides stability and drainage.

StarStarStarStar

Warm Mix Asphalt (WMA)

StarStarStarStar

Properties: Produced at lower temperatures, energy-efficient, reduced emissions. Common Uses: Pavements with similar performance to HMA.

StarStarStarStar

Chip Seal

StarStarStarStar

Properties: Layer of asphalt emulsion followed by aggregate chips. Common Uses: Surface treatment, provides skid resistance, extends pavement life.

StarStarStarStar

Fiber-Reinforced Concrete

StarStarStarStar

Properties: Contains fibrous material, increased tensile strength, reduces cracking. Common Uses: Overlays, bridge decks, joint-less pavements.

StarStarStarStar

Geotextiles

StarStarStarStar

Properties: Synthetic fibers, permeable, enhances soil strength. Common Uses: Soil reinforcement, filtration, separation layers beneath pavements.

StarStarStarStar

Cold Mix Asphalt

StarStarStarStar

Properties: Applied at ambient temperatures, maintains workability for longer periods. Common Uses: Temporary patching material, low-traffic roads, emergency repairs.

StarStarStarStar

Base Course

StarStarStarStar

Properties: High quality aggregates, compactable, bears structural loads. Common Uses: Sub-layer for asphalt and concrete pavements, supports surface layer.

StarStarStarStar

Bitumen

StarStarStarStar

Properties: Highly viscous, black, sticky. Common Uses: Binder in asphalt concrete, road construction, waterproofing.

StarStarStarStar

Steel

StarStarStarStar

Properties: High tensile strength, ductility, recyclable. Common Uses: Reinforcement in concrete, bridge structures, guardrails.

StarStarStarStar

Tire-Derived Aggregate (TDA)

StarStarStarStar

Properties: Made from shredded tires, lightweight, provides good drainage. Common Uses: Subbase for roadways, backfill material, landfill projects.
