PRO V ASPHALT ANCHOR

The PRO V asphalt anchor is a high strength, internally threaded socket combined with PROV 200 injection resin, a chemical anchor resin designed for asphalt, tarmac, concrete and solid substrates.

It is suitable for temporary or permanent fixings including cycle lane bollards, traffic calming measures, parking barriers, fencing, shelters and edge protection. Performance loads up to 35kN in recent tests.

Why expansion anchors don't work in asphalt

Traditionally, expansion anchors designed for concrete (plug and screw, screw bolts etc) have been used in asphalt. Expansion anchors work by constantly pressing on the drill hole wall and are held in place by friction locking. As long as the base material does not yield, the anchor will remain in place.

It is estimated that asphalt is twenty times more yielding than concrete.

The constant pressure exerted by expansion anchors causes the asphalt to yield with subsequent loss of friction locking, resulting in the failure of the anchor typically within days. It therefore follows that expansion anchors cannot safely be used in asphalt. 

Why PRO V asphalt anchors work in asphalt

In contrast to expansion anchors, PRO V asphalt anchors combines PRO V200 injection resin with a high strength internally threaded socket to chemically bond to the base material imparting no stress either during the installation or the lifetime of the anchor. 

Using the PRO V asphalt anchor negates the need to dig out sections of asphalt and pour concrete to form a fixing point enabling you to fix directly into the asphalt.

How PRO V asphalt anchors work

To install PRO V asphalt anchors, a hole is drilled in the asphalt and filled with PRO V200 injection resin. The internally threaded socket is slowly twisted into the resin until it is flush with the surface. The displaced resin is forced into the cracks and voids in the asphalt and any gravel layer below, creating a very strong bond. The installed anchor has now formed the equivalent of a concrete plug or cone in the asphalt. 

Base materials: asphalt, tarmac, concrete
Base material condition: dry, wet, water filled.
