Central Reserve Hardening

Central Reserve Hardening

Central reservations have for decades been a tactical issue for contractors, long narrow trenches usually full of drainage and coms ducts has made them troublesome and time consuming. Central reservations have been a key field of revenue for Sidewinder® paving since the early 90’s and with the advent of VCB’s over the last 10-15 years is still an area that Sidewinders® can save you time and money.

The Sidewinders® ability to place and grade all layers from capping to wearing coarse from 300mm wide to 3.0 meters wide and from 1.0 meter below to 200mm above carriageway at virtually any grade or profile makes this job easier to program and faster to complete.

Material Cost Savings

An advantage inherent in the use of our Sidewinders® for central reserve paving is the opportunity to lighten the construction detail thus offering material cost savings. Since there is no need for any delivery trucks or plant other than the rollers providing compaction to sit in the central reserve there is a significantly reduced risk of damage to any underground services or utilities.

Vehicle Restraint System Schemes

With concrete barriers being adopted as the standard Vehicle Restraint System on UK motorway and trunk road networks, our Sidewinders® play a significant role in VRS schemes.

Sidewinder® involvement on VRS schemes has consistently proven to out-perform all other traditional or alternative methods of construction surfacing. Accurate and consistent level control through adopted laser levelling systems combined with the ease of material feed to the laying area provides a consistent, quality finish whilst yielding higher outputs.
