To account for this, mechanistic-empirical design performance prediction models include thermal property inputs such as solar absorption. Temperature-related asphalt pavement distresses such as rutting and fatigue are influenced by pavement albedo. Pavements with lower albedo tend to absorb more solar energy, resulting in higher pavement temperatures, whereas pavements with higher albedo typically absorb less solar energy, resulting in cooler pavement temperatures.

When trying to decide between concrete vs asphalt roads, it's important to consider the specifics of your project first and foremost.Ĭhoosing material for your paving project can't be decided on initial costs alone. There is no simple answer to the question of which material is preferable. Concrete Vs Asphalt Roads: Which is Better? With only a 10-year lifespan, asphalt must be re-laid or repaired on a much more regular basis. This happens regardless of new production or recycling.Īsphalt is a cheaper and faster solution for short-term projects, but the repairs are sometimes just as extensive as concrete. The process of melting asphalt creates greenhouses gasses, which contribute to environmental pollution. Budgeting for small roadway repairs or patching is much simpler and faster than replacing entire slabs of roadways on less heavily trafficked areas such as country roads. Heat absorbing into asphalt creates an ideal atmosphere for snow melt and moisture evaporation.Īsphalt is ideal for rural roadways because of the ease of maintenance and repair. Since asphalt is black, it utilizes the natural heat from the sun to help keep the roads clear after storms. Though it creates a smooth drive, it also boasts better traction and skid resistance. When melted down, it can be used again to create new roadways.
Like concrete, asphalt is 100% recyclable. Advantages of Asphalt RoadsĪsphalt has an attractive price point, even as prices have slowly begun to creep up over time. This material is also more prone to slippage during rain or snow. Spills, vehicle chemicals, and other pollutants do not absorb into concrete as well as asphalt. The costs of concrete roads are also higher than that of asphalt, both in installation and repair.Ĭoncrete is not as "grippy" as asphalt, either.
This, and slabs settling over time, can make for a somewhat bumpy and noisy roadway. In order to create enough grip on the road, texture is brushed into the surface. Holes or cracks can't be simply patched-instead, entire slabs must be replaced.Ĭoncrete doesn't always make for a smooth ride, either. Though concrete lasts a long time, repairing it is a bigger chore. Concrete is also produced from limestone, which is widely available. Producing it creates less environmental pollution, and cars run with better fuel efficiency on concrete. Where asphalt tends to embrittle over time, concrete is more hearty.Ĭoncrete tends to be a greener material. Though not immune to the freeze-thaw cycle, concrete is more resistant. This sturdy surface is less prone to dips and rutting, meaning it is a favorite for freeway construction. High truck volume is better suited to concrete roads, as they hold up better under the weight and pressure. Once crushed into gravel, concrete can be used in a variety of ways. Lasting 20-40 years on average, paving in concrete can boast two to four times the lifespan of asphalt.Ĭoncrete, it may surprise you to know, is recyclable. The biggest benefit of concrete road construction is the longevity. Read on to discover the pros and cons of concrete vs asphalt roads. However, it's not always apparent which paving method is the best for your job. Where the idea of an open road used to conjure smooth blacktops radiating heat from the sun, today's roads are turning more gray.Ĭoncrete road paving is quickly reaching the same popularity as asphalt, and the reasons are many. Discover the pros and cons of each as we compare concrete vs asphalt roads.
