What are the characteristics of different types of pavements?
resistance to loads
low rolling resistance
ease of maintenance
adequate color
The pavements suffer complex efforts that can be grouped into two categories: efforts produced by vehicle traffic and efforts produced by variations in humidity and temperature.
The static loads can reach important values, and the pavements must have elastic capacity to return to their normal position when the load disappears.
The pavements with high friction coefficient allow good braking, even under rain or frost.
The pavements with low noise do not excessively increase urban noise.
The dark-colored pavements make it difficult to see, especially at night, requiring an increase in signage and lighting.
The pavements made with concrete blocks have a strong initial contraction due to the effect of the grip that occurs, especially in the first days after molding.
The pavements made with asphalt tend to enter slow flow, especially when combined with loads that repeat systematically and with a strong incidence of sun on them, raising their temperature to levels close to 70°C.
The pavements made with asphalt are very sensitive to moisture in their base.
The pavements made with concrete blocks have a significant problem with contraction and expansion joints.
The pavements made with asphalt are the easiest to repair and, once repaired, traffic can be released in a few hours.
The pavements made with concrete blocks have a more difficult maintenance and take at least seven days to be released after repair.
The color of the pavement is important for visibility and temperature control.
The pre-mixed asphalt pavements are more expensive but of higher quality than the superficial treatment pavements.
The asphalt mixture is spread on the pavement by a special truck and then compacted with tire and smooth rollers.
The pavements made with concrete blocks can be divided into two groups: blocks without articulation and blocks with articulation.
