1. GENERAL DESCRIPTION:

Maxi-Crete F is a BBA HAPAS approved material and is used extensively as a recess repair system in many airfield pavements. Maxi-Crete F is also widely used as a Stress Absorbing Membrane Interlayer (SAMI) on surfaces due to be overlaid, thus reducing the effects of reflective cracking in the new asphalt overlay.

Maxi-Crete F20 and F40 can be installed to any depth and width, however for depths up to 40mm it is advised to F20 is used but laid in tow layers of 20mm. F20 is the preferred system for use on runways and taxiways because the finer aggregates provide a smoother surface finish. F40 can be used for repairs deeper than 40mm but it is advised that the top 20mm is finished off with F20. By recessing the F20 and F40 into the pavement surface it will greatly prolong the service life and enhance ride quality.

Maxi-Crete F is a black, pre-mixed, hot applied, high modulus, polymerised resin compound incorporating fillers, aggregates and rubber and other mineral fillers.

Fine aggregate (2 – 3mm) granite, basalt or bauxite can be used on the surface of the repair to meet friction and texture depth requirements or to be sympathetic to the adjacent surface colour; however this is not recommended on runways and taxiways because of potential FOD issues due to possible loose aggregates.

Maxi-Crete F offers extremely good adhesion to asphalt surfaces and is formulated to have excellent anti-oxidation properties. In its molten state

Maxi-Crete F has excellent flow properties thereby ensuring total penetration of the crack / recess. Following cooling it sets to a touch, load-bearing repair that is capable of maintaining flexibility through a wide range of temperatures, and will ensure optimum compressive resistance.

2. BENEFITS:

BBA HAPAS approved
Prolongs the life of cracked pavements
Prevents the ingress of water and de-icing salts
Enhances ride quality
Simply heat and apply
Minimal traffic disruption

3. APPLICATIONS:

Roads and Highways
All Airfield Pavements
Industrial Hardstandings
Surface Car Parks

4. INSTALLATION:

Weather Conditions: Installation of the material shall only be carried out on a surface temperature >-0ºc. Below freezing temperatures extra care must be taken with preparation and when applying primer to surface.

Preparation of the Surface: The existing surface is mechanically planed-out, centrally over the length of the cracks to a depth of up to 100mm. The width of the recess should be formed to extend at least 25mm into the sound surface. Typically widths of recess can be 100 – 1000mm. The recess must be clean and dry and free from all loose aggregate, moribund sealants, road salt and any other loose material. Cleaning with hot compressed air is essntial.

5. SYSTEM INSTALLATION PROCEDURE:

SYSTEM 1 – MAXI-CRETE F20 & F40 IN COMBINATION:

Where areas of reflective cracking are evident and further movement is expected the system should incorporate the Maxi-Crete F20 material as a surface course and Maxi-Crete F40 as a base course, the following methods should be applied:

5.1 Maxi-Crete F40 is melted in horizontal mixer-heaters that are agitated at a rate of ≥10 RPM to a laying temperature of between 180ºc and 210ºc. The materials must be kept at this temperature for a period of 40 minutes before using.

5.2 Maxi-Crete F40 is poured into the prepared recess and leveled using a hot tool to finish within approximately 20mm of the adjacent surface. If the depth of the recess is >40mm Maxi-Crete F40 materials should be applied in layers between 20 – 40mm.

5.3 Maxi-Crete F20 is melted down in horizontal mixer-heaters that are agitated at a rate of ≥10 RPM to a laying temperature of between 180ºc and 210ºc.

5.4 Maxi-Crete F20 is poured into the prepare recess in a layer approximately 20mm deep via a screed box, to finish flush and overlap onto the adjacent surface by 10mm. The application of the Maxi-Crete F20 surface material must be applied onto, the Maxi-Crete F40 base material before its temperature falls below 25ºc. Should the temperature fall below 25ºc the recess and Maxi-Crete F40 surface must be carefully re-heated using a gas and air lance.

5.5 Whilst the Maxi-Crete material is still in a molten state, ≥75ºc a covering of pre-heated 3mm aggregate (≥100ºc) is applied to the surface.

5.6 Once the repair has cured (30 minutes to 120 minutes) the work area is mechanically swept to remove any excess aggregate.

SYSTEM 2 – MAXI-CRETE F20:

When repairs are being undertaken in surfaces where no or minor movement is anticipated, the following method should be applied:

5.7 Maxi-Crete F20 is melted in dedicated horizontal mixer-heaters that are agitated at a rate of ≥10 RPM to a laying temperature of between 180ºc and 210ºc.

5.8 Maxi-Crete F20 is poured into the prepared recess and levelled using a smoothing iron or a screed box to finish flush with the adjacent surface. If the dpth of the recess is >20mm Maxi-Crete F20 should not be applied in layers >20mm.

5.9 Whilst the Maxi-Crete F20 material is still in a molten state ≥75ºc a covering of pre-heated3mm-5mm aggregate (≥100ºc) is applied to the surface.

5.10 Once the repair has cured (30 to 120 minutes) the work area is mechanically swept to remove any excess aggregate.

5.11 During the curing period no disturbance or trafficking of the repaired area should be permitted.

Safety Data Sheet Part B PDF

1. GENERAL DESCRIPTION:

PEP-Coat 2010 Surfacing System is designed to seal and protect concrete pavements from erosion, frost damage, aircraft fuel spillage and de-icing chemicals. The system will prolong the service life of the concrete, arrest further deterioration and protect from freeze/thaw damage. It will also greatly reduce the risk of FOD from loose stones and other debris. If a high friction finish is required, suitable high PSV aggregates can be applied to the final wearing surface.

PEP-Coat 2010 Surfacing System is a uniquely formulated, three-part, deep penetrating epoxy resin that is hand applied directly to prepared concrete surfaces. With an integral, fine, hard wearing surface aggregate, PEP-Coat 2010 provides an extremely robust finish that will withstand high volumes of aircraft traffic. PEP-Coat 2010 has an initial cure of 3 – 6 hours with full curing at approximately 48 hours depending on ambient temperatures.

2. BENEFITS:

• Extends the life of concrete pavements
• Prevents water ingress – freeze/thaw protection
• High friction finish
• Protects surface from aviation fuel spillage and de-icing materials
• Improves skid resistance
• Reduces foreign object damage (FOD)
• Durable surface protection
• Cost-effective alternative to full depth repairs
• Less disruptive than full bay replacement
• Fast cure – minimal disruption
• High performance system

3. APPLICATION:

• All Airfield Concrete Pavements
• Car Park Ramps and Decks

4. INSTALLATION:

Weather Conditions: Installation should only be carried out on surfaces that are completely dry and where the surface temperature is >5ºc.

Preparation of the Surface: The area being treated should be cleaned and dried, removing all loose material, dirt, dust and foreign matter. Captive shot blasting or other mechanical means shall be considered as a method of preparing the surface particularly if there is a build-up of dirt, coatings or other contaminates.

5. SYSTEM INSTALLATION PROCEDURE:

5.1 The surface of the concrete is to be warmed by applying hot compressed air. The combination of the propane gas mixed with the compressed air gives off intense heat which is used to vaporise any oil, water or liquid contaminants on the surface of the concrete.

5.2 A unit of PEP-Coat 2010 Part A is added to Part B and thoroughly mixed with a suitable mechanical mixer for 3 – 5 minutes.

5.3 Once the materials are evenly mixed apply them immediately onto the prepared, warm, dry concrete surface using a brush, coarse roller or squeegee and ensure that the exposed area is fully covered. Work the material into the edges and the deeper voids taking care not to allow the material to form puddles.

5.4 As soon as the surface is fully coated with the resin, evenly broadcast the chosen aggregate onto the surface ensuring that all the wet resin is fully covered and no wet patches are showing through. The cover rate will vary and is affected by the film thickness and the condition of the host surface being treated. The cover rate will therefore vary from a minimum of 800g / m2 upwards; the aggregate usage will depend on the size being used. Coursegrade quartz will be applied at approximately 4kg / m2 and a 1 – 1.2 graded aggregate will be applied at approximately 5 – 6kg / m2.

5.5 The pot-life of mixed PEP-Coat 2010 is approximately 20 minutes so care should be taken to ensure the material is spread onto the prepared surface without delay and the chosen aggregates applied immediately.

5.6 The curing time of the applied PEP-Coat 2010 System will greatly depend on the ambient temperature but initial cure will occur within 3 – 6 hours. During the curing period no disturbance or trafficking should be permitted.

5.7 When the surface is fully cured and prior to opening to traffic any excess aggregate can be swept off, either by hand or using a mechanical vacuum sweeper. When attempting the first sweep it is important to ensure the surface is fully cured and the sweeper brushes do not dislodge any of the aggregate from the resin.

5.8 Once the PEP-Coat is fully cured further sweeping will be necessary until all shedding of the aggregate has taken place. The first attempt should be by vacuuming rather than by sweeping so as not to dislodge any aggregates from the resin. Further sweeping will be necessary until the initial shedding of aggregates has taken place.

5.9 If the aggregate is clean and dry it can be re-used, wet aggregate should not be used for any part of the PEP-Coat process.

1. GENERAL DESCRIPTION:

Iron Guard is a revolutionary HAPAS approved, polymer based, bituminous repair system developed for the reinstatement of all types of ironwork on highways and airfields in asphalt and concrete pavements. Producing a permanent repair, Iron Guard is a 100% on-site process and requires no subsequent maintenance.

The system comprises high quality bedding mortar, interlocking mono-polymer bricks (BS5834 and EN124), polymer modified mastic grout and H grade cold polymer mastic asphalt blocks (BS1447:1988).

The cold blocks are designed to absorb the heat from the hot liquid grout whilst forming a monolithic structure with the mono-polymer bricks, which are in turn supporting the frame and cover. The system cools to an ambient temperature faster than other hot applied systems allowing repairs to be completed and the area to be re-opened within restricted working periods.

Pre-coated chippings or 2 – 5mm aggregates >60 PSV are applied to the finished surface to provide a non-skid surfacing compliant with UK legislative specifications.

Iron Guard can incorporate recycled coarse aggregate. It is voidless, requires no compaction and in many cases can be trafficked within an hour of completion.

When using Iron Guard there is no waste and no need to collect hot materials from the asphalt plant.

2. APPLICATION:

Iron Guard is suitable for use on all inset ironwork including manholes, gullies.

4. INSTALLATION:

Weather Conditions: Installation cannot be carried out during heavy rain or where there is running water.

5. SYSTEM INSTALLATION PROCEDURE:

5.1 Mark out the area to be excavated around the frame of the failed ironwork.

5.2 All perimeter edges around the failed ironwork must be saw-cut to ensure a clean vertical face. Break out the materials and remove all spoil and debris and the cover and frame. Any loose debris can be removed using hot compressed air and care should be taken to stop debris falling into the shaft. If re-using the existing frame remove all old bedding material and any debris from the frame in preparation for reinstallation.

5.3 Apply the quick setting Iron Guard bedding mortar to the base of the excavation to a maximum thickness of 50mm.

5.4 If the area to be repaired is concrete a primer such as Crete-Prime must be applied to all exposed surfaces and allowed to cure for approximately 15 minutes before installing the Iron Guard bricks, grout and blocks. Reinstatements in asphalt do not require priming.

5.5 Place a layer of Iron Guard interlocking mono-polymer bricks onto the Iron Guard bedding mortar ensuring that as much of the mortar is covered with the interlocked bricks as possible.

5.6 Reset the new / existing ironwork on top of the bricks so the frame is level with the surrounding surface and allow the bedding mortar to cure for a minimum of 15 minutes dependent on the ambient temperature.

5.7 In a thermostatically controlled mixer heat the Iron Guard polymer modified mastic grout to a maximum of 180°c. To avoid any localized overheating of the grout during the melting process always keep the mixer paddles turning. Once the grout has reached its optimum working temperature and is thoroughly mixed, pour the heated grout into the excavation to a depth of 20 – 25mm, ensuring all faces of the excavation are covered.

5.8 Lightly bed the Iron Guard blocks into the hot Iron Guard grout with sufficient space between them to allow the grout to flow and fill the voids around each block. Allow the grout to cool.

5.9 The Iron Guard blocks give extra strength to the reinstatement and act as a heat sink, drawing heat from the grout.

5.10 For deeper excavations rebuild the sub-base to the bottom of the binder base course before applying the Iron Guard system. Fill the excavation with a second application of the hot Iron Guard grout and hand float the surface of the grout to ensure the material is level with the surrounding road surface.

5.11 Cold pre-coated chippings, or 2 – 5mm aggregates heated to 140°c and with a PSV >60 should be pressed into the grout with a wooden float whilst the material is in a warm plastic state (75 – 90°c).

5.12 Allow the reinstatement to cool to ambient temperature before opening to traffic. The curing time will greatly depend on the ambient temperature. Initial cure can occur within approximately 2 hours but full cure may take up to 12 hours. During the first hour of curing traffic must not be allowed onto the treated surface. Once fully cured sweeping or vacuuming can take place.

6. PACKAGING & STORAGE:

STORAGE: Store in a cool, dry, well-ventilated suitable for storing flammable materials.
PACKAGING: Packaging will vary according to materials.
SHELF LIFE: Shelf life of all materials is 2 years if stored in the original, unopened packaging in a dry place at 5 – 30°c.

7. WARRANTY:

The Company warrants that the materials meet stated specifications at the time of dispatch from the factory. Techniques used for the preparation of the repair prior to application are beyond the Company’s control, as are the use and application of the materials. The Company shall not be responsible for improperly applied or misused materials. There shall be no other warranties expressed or implied.
