Scraper Finish
Used on smooth asphalt, reducing noise and improving skid resistance

Bead Pouring
Used on chip seal surfaces to ensure better penetration into cracks

Used on wide cracking to provide sufficient bondage on either side of the crack

The key qualities of crack sealing products are their flexibility, suitability to local weather conditions and that they are applied hot and are skid resistant.
An effective crack sealant must have excellent torsional recovery within the crack, withstanding repeated expansion and contractions in the pavement. This flexibility must exist over a wide range of temperatures and have a high softening point to ensure that the product will not bleed in hot conditions.

Suitable plant with heating capabilities is necessary when undertaking crack sealing operations. As the sealant is classified as dangerous goods, appropriate signage and qualifications are required. Ideally the works should be done by an all-in-one unit that can work at a good pace as a mobile worksite, causing minimal traffic disruption.

Asphalt Repairs

You want asphalt repairs to be done with the right techniques to ensure they last as long as possible. However, even with the right techniques used, often patches fail as they have not bonded with the existing pavement and water and debris enter the surface. Crack sealing around the edge of new patches forms a waterproof bond and increases the longevity of the repairs.

When overlaying existing asphalt, it is vitally important to crack seal prior to works to prevent reflective cracking. If new asphalt is laid on failed pavement, the cracks in the base will undermine the new overlay and produce new cracks.
