The most common reason for pavement failure is moisture penetrating the surface
Cracks in pavements allow moisture to penetrate the surface which causes pavement material failure. Failure to seal cracks results in further cracking, potholes and eventually a major pavement breakdown, leading to unnecessary expensive repairs.
To minimise the water infiltrating the pavement base, crack sealing with a hot polymer/rubberised bitumen sealant is required, preventing future pavement problems.
Crack sealing is an extremely economical way of maintaining pavements. It is very cheap and effective when compared to undertaking other more extensive works such as resurfacing and reconstructing.
Crack sealing is a practical and cost effective measure and is part of any good pavement management program for all roads.
Early intervention is vital in prolonging the life of pavements. Once you can see pavement failure on the surface, the rate of deterioration accelerates. Crack sealing is a key element in early intervention as it slows the deterioration process and can significantly add to the life of a pavement, maximizing your asphalt investment
