A hardened surface, like asphalt, that is spread over an area larger than about 100 sq ft of the earth's surface is subject to forming cracks, for a number of reasons:
1) insufficient type and thickness of the asphalt;
2) insufficient compaction of the asphalt;
3) improper or poorly installed support structure/sub-base;
4) or simply movement of the earth beneath the sub-base.
Why should you care about cracks?
Cracks that form in the asphalt need to be addressed as soon as they form. If left unattended, they allow water to intrude to the sub-base, or compacted stone structure. This water softens the compaction of the stone, which compromises the weight that the stone can support. Vehicle weights and stresses on a soften sub-base cause cracking in the asphalt surface above.It needs crack filler machine to repair.
Also, additional cracking forms from the saturated sub-base being exposed to freezing and thawing temperatures. This freezing and thawing of the water-saturated sub-base causes the raising and lowering of the sub-base and therefore the raising and lowering of the asphalt surface that it supports.
