Repair of a cracked road surface

Successful test installation of TenCate Polyfelt® PGM-B in Nijverdal

Challenge

Asphalt interlayer systems have to fulfil the functions of stress relief, barrier and reinforcement. Different raw materials have been used for asphalt reinforcement. It is more and more acknowledged that e.g. PET yarns have certain limitations in asphalt reinforcement due to their relatively low modulus. In many cases glass fibres have been used, now a new and innovative material has proven its suitability: TenCate Polyfelt® PGM-B using high modulus basalt fibres.

Solution

An effective way to avoid cracks is to take up stress by using extremely stiff components. The degree of success is mainly determined by proper bonding and sufficient stiffness. Basalt is an innovative mineral material providing high tensile stiffness and perfect bonding to bitumen, and therefore optimum reinforcing properties. Thus, the multi-layered asphalt system can be reinforced by adequate interlayers if it succeeds in transferring the required forces from the asphaltic matrix to the interlayer and vice-versa.

Benefit

TenCate Polyfelt® PGM-B provides a higher quality surface, longer maintenance intervals and a morecost- effective way of road maintenance than conventional methods.

• High tensile strength / higher stiffness
• Better affinity to bitumen
• 3 functions in one product
