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.
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.
