Asphalt Driveways - All About Asphalt Driveways

Asphalt is pliable, making it much more forgiving than concrete when it comes to heaving from freeze and thaw cycles. Asphalt is also an excellent choice if you happen to live in a snowy region. The black color can soak in the heat from the sun and melt snow much faster than any other type of driveway surface.

The Causes of Potholes on Roads, Their Effects and Control

The asphalt pavement failure occurs due to the presence of water in the underlying soil structure and the presence of traffic passing over the affected area on the road. The water in the underlying soil structure can come from floods, underground erosions, or cracks from the road surface" Having explained what pothole is and its causing factor.

Deterioration starts on a very minute scale with micro-cracks in the asphalt, the loss of a few granules, dissipating volatiles, and chemical changes in the asphalt. The rate at which aging increases depends on a number of factors, such as shingle quality, roof orientation, slope, and other factors.

Challenges and solutions for crack sealing in asphalt

Surface cracking in asphalt concrete is a major failure mechanism that develops over the pavement service life. In general, surface cracks are primarily caused by traffic loading and temperature variations [1]. It is well recognized that water infiltration through cracks may accelerate pavement deterioration resulting in major problems such as moisture damage, base failure, and potholes [2; 3].

Five Causes Of Concrete Erosion & How To Prevent Them

2. Freezing or Seeping Water. Water is the leading cause of concrete deterioration and degradation. Concrete paving is quite porous in its design, which allows water, especially rainwater, to seep into the structure and degrade it over time. The water volume rises when it freezes, which pushes and separates the rocks, ultimately causing erosion

Summer Asphalt Paving Damage | Richmond Blacktop

Jun 15,  · But asphalt heating up in the summer can have its negative effects. When sunlight hits the surface, it begins to oxidize, deteriorate and dry out the liquid asphalt (glue) that holds together the aggregate. This leads to a shrunken surface with cracks that allow water to seep through and further damage the asphalt.
