Concrete is Better

Concrete, a material used since the Roman Empire, boasts a number of benefits for its use in road paving.  Concrete is extremely durable, gradually hardening over time and gaining 10% in strength over its lifetime. Unaffected by the freeze-thaw cycle that generates potholes in
other paving materials, concrete remains strong with an average life-expectancy of 30 years. In use for 80 years, Mountain Street in Ft. Collins is one of many examples of a concrete road that has lasted well
beyond this.

Concrete offers many safety benefits, including better visibility as it reflects light, and also prevents water from accumulating, reducing dangerous instances of hydroplaning. Rather than gathering in pools, water on pervious concrete is captured and allowed to filter into underlying soil.

Repairs on concrete paved roads are typically more minor than
those of other paving materials because of its durability. A
new section of  concrete pavement can be open to traffic
within 12 hours. Comfort is yet another benefit of concrete,
with the even, hard, surfaces of concrete paved roads
providing a smooth ride for commuters. Electing to
implement concrete paving would provide Colorado
taxpayers the opportunity to drive on “the Cadillac
of road paving” for decades to come.

How Potholes Are Formed

Typically, potholes are caused by freeze-thaw cycles, where snow and ice melt, allowing water to seep below pavement through cracks created by wear and tear. Dropping temperatures then cause water to become ice, expanding beneath the pavements' surface and forcing it to rise. Once this has occurred, continuous traffic and rising temperatures combine to form a break in the pavement, and a pothole is born.
