Among the available materials for paving roads and driveways, asphalt has been the choice of several paving contractor for the many advantages it has over other materials like concrete. There are a great number of asphalt solutions for urban, suburban or rural roads that may greatly be useful in dealing with the stresses of heavy traffic.

Next, the laying of asphalt only takes one to two 2 days to complete whereas concrete takes several days longer. Gleam big difference in the time of usability of asphalt and concrete. Asphalt paving can already be utilized after 2 to 4 days according to the time of year when the paving is laid, for instance it cures or hardens faster in the Spring and Fall and takes longer in the Summer because the summer heat causes it to melt, while concrete paving may only be used after 7 days after it really is placed. Concrete may takes less time and energy to harden if a high early mix which is quite expensive.
General road maintenance is essential to lengthen the life of the street structure this is why paving contractors prefer asphalt over concrete. When paver stones and maintenance is necessary, asphalt could be easily opened and can be placed back quickly thereby the flow of traffic isn't affected.

Cracking is also a big issue for paving contractors. While concrete needs central joints to avoid it from cracking, asphalt is highly flexible which means that the pavement is less inclined to split or break. Also, asphalt is 100% recyclable thus deploying it rather than concrete may preserve non-renewable natural resources.
Noise both on the inside and outside the vehicle could be greatly reduced when asphalt can be used for paving. Actually, among all the traditional road surfaces asphalt roads have already been proven to have the cheapest noise level. Also the recent development of porous asphalts has reduced the noise level even further.
