What is Asphalt?
Asphalt pavement is normally 95% aggregate and 5% asphalt cement as the binder. Aggregate is a mixture of stone, sand, and gravel. The asphalt binder is an oil-based product refined and used to bind the aggregates together.
Installing asphalt pavement from the ground up involves several processes. First, the area to be paved needs to be clean and the soil compacted. Next, a stone mix such as 21a is applied as a base, compacted for stability, and graded for drainage. Finally, hot asphalt laid and compacted over the base layer. Sometimes concrete or stone edging is installed to protect the edges of the pavement. Once the asphalt cures, parking lines and pavement markings can be painted with reflective traffic paint.
Benefits of Asphalt
Long-Lasting – Asphalt pavement is very durable (when properly installed and maintained, it can last for decades)
Provides Proper Drainage – Correctly graded pavement lets water flow into the right places to reduce soil erosion.
Cost-effective – Compared to other pavement types such as concrete or brick, asphalt costs a fraction to install and maintain.
Speed of installation – Most asphalt-related projects only require a day to complete incurring the least inconvenience to our customers
Asphalt Repair Services
All of this pavement damage can be fixed by various asphalt pavement repair processes.
Pothole repair involves cleaning and filling holes with high quality binders.
Crack filling uses hot asphalt binders either injected or poured into the cracks to seal the pavement.
Asphalt overlays spread a new asphalt layer over existing pavement with surface damage, making use of an undamaged base layer.
Sealcoating can provide a new surface to damaged asphalt, as well as protect the pavement against further wear and weathering.
Common Asphalt Damages
Though asphalt is designed to withstand wear, time and weathering can break down the pavement. Alligator cracks, relatively shallow interconnecting cracks, are caused by repeated stress to an improperly applied asphalt layer. Temperature causing expansion and contraction can also lead to cracks. When cracks in the asphalt go deep into the gravel base, the pavement can shift, causing more cracking. An insufficient slope can let water pool on the asphalt, leading to potholes.
What is concrete?
Concrete is a structural material consisting of a hard, chemically inert particulate substance, known as aggregate (usually sand and gravel), that is bonded together by cement and waste.
Installing concrete from the ground up involves several processes. First, you have to form the slab then pour the mix material. After that you need to level it out by hand. While you wait for it to dry and set you have to finish the top by pushing all the rocks to the bottom to make it smooth to give it the finished desired look.
Benefits of concrete
Very durable- Can last up to 50 years
Low maintenance- Doesn't need to be touched up (possible power wash for "clean/fresh" look)
Does not rust, rot, or burn
Wind and water resistant
Higher surface density than asphalt
