Q. 1 What is hydraulic retexturing?
A.Hydraulic retexturing is the treatment of the road surface with ultra high pressure water and suction recovery to achieve improved texture and skidding resistance.
Q. 2 Which surfacing materials can be treated with our retexturing machines?
A. All the main surfacing materials can be treated hot rolled asphalts, stone mastic asphalts and thin surfacings.
Q. 3 How long will the treatment last?
A. This depends very much on volume of traffic. The treatment restores the surfacing back to its original properties, and is even used to give “accelerated wear” on SMA's immediately after laying.
Q. 4 Will it harm the existing surfacing material?
A. Provided the existing material is structurally sound, there will be no damage to the road surface. Our process gives variable pressures, flows and speed to cater for every different section of road.
Q. 5 What pressures do you use?
A. As stated above, the pressure used depends on the existing surfacing. Our equipment operates at pressures from 500 bar (7,250 psi) up to 3000 bar (43,500 psi) but usually between 2000 bar (29,000psi) and 2500 bar (36,250 psi).
Q. 6 What happens to the arisings from the process?
A. All dirty water is removed from site by a licensed waste carrier and disposed of to Environment Agency standards and all solids are taken to a licensed land fill.
Q. 7 Can our retexturing machines clean concrete?
A. Absolutely, MERLIN and OSPREY clean concrete with little effort. Usually prior to a thin surfacing application.
