Description

 

HTS Cycleway material is a thermoplastic hot screed treatment consisting of a polymer modified binder incorporating selected high PSV aggregates, mineral extender and pigment.  The product is suitable for application on concrete and asphalt surfaces and is applied to a finished thickness of 2 - 3mm to provide a high visibility surfacing which is both durable and skid resistant. 

 

Uses

 

HTS Cycleway treatments are used to create dedicated cycle routes and to highlight cycling reservoirs at traffic junctions to help cyclists negotiate heavily trafficked areas safely.

Application

 

The material shall be applied transversely across the road surface using a screed box with a suitable trailing edge allowing the encapsulated aggregate to be evenly distributed.  On an average textured surface (TD = 1.5), the material shall be applied at a rate of 7.5 - 8.5kg/m² (120-140m²/tonne) and finished to give an even, durable and textured surface free of lumps and other blemishes. 

 

Aftercare

 

The finished surfacing can be trafficked once the installation has reached the ambient temperature of the adjacent road surface

 

Material Performance

 

The properties of the installed HTS Cycleway material shall conform to the requirements given in Table 3.
