ASI Solutions | RHiNOPHALT® Car Park Treatment & Marking Realignment
With millions of cars on the World’s roads, it is not surprising that car parks form an essential part of transport infrastructure. Asphalt maintenance causes disruption and can be an issue with owners and engineers struggling to balance surface condition with free access.
Degraded surfaces and potholes, apart from the health and safety considerations, can persuade members of the public to spend their money elsewhere and can have a direct effect on retail profits. The car park surface is the first thing customers see and can often influence their overall impression of the facility.
RHiNOPHALT® can be applied at night which works well with maintenance programming, and the quick curing time means that the markings can be applied in the same closure window. Application can be completed via different vehicles depending on the size of the areas to be treated, taking into consideration restricted access points and site obstacles.
All large retail organisations listen to their customers, many are now changing the width of parking bays due to the high incidence of minor impact damage and subsequent claims/complaints from users. The black surface finish provides a quick, cost effective solution when line marking removal and re-alignment is carried out, without the need to replace the asphalt surface course.
RHiNOPHALT® treatment can ensure that a car park’s asphalt surface remains in good condition and aesthetically pleasing. The preservation process can extend the life of this valuable asset and provides the following benefits:
• Extends the life by delaying resurfacing
• Rapid delivery reduces closures
• Significant whole life costing savings
• Reduction in carbon footprint
• Allows for regeneration rather than replacement

RHiNOPHALT® Product Overview
RHiNOPHALT® is a cold spray-applied surface penetrative sealer applied at ambient temperature. It is a cost-effective and sustainable method of preserving and protecting bituminous bound materials. The preservative protects bitumen from the impact of oxidisation due to weathering and UV degradation. It achieves this by penetrating the existing asphalt binder of the surface course and provides a durable seal to prevent water ingress into the bitumen and to resist further oxidisation; coupled with this is the benefit of improved cohesion and binding properties with the aggregate matrix.
The solution is best utilised as a preventative maintenance measure in asset management, extending the operational life of the asphalt structure and reducing the large costs associated with resurfacing and repair works.
Rather than adding a new layer of surface, RHiNOPHALT® seals in essential oils and resins, whilst at the same time improving the binding and waterproofing properties of the existing structure. As a result, the treated surface will become more resistant to abrasion, stone loss, water ingress and the severe ageing effects of extreme temperatures. By minimising the occurrence of cracking, crazing and potholes, RHiNOPHALT® dramatically reduces the need for reactive maintenance and has been demonstrated to provide significant life extension to the surface course, thereby delaying the need for resurfacing or other remedial treatments.
The first ever RHiNOPHALT® treatment in the UK was at Kiln Farm Business Park (Milton Keynes), on the one of the car parks. 2,000m2 was treated in August 1997. This contract had many visitors and really demonstrated the company’s capability at treating a large area in a short period of time.
In July 2000, another 2,000m2 of car parks were treated in South Wales for Neath & Port Talbot Councils.
In June 2009, ASI treated 15,000m2 of parking area at Southampton Hospital. Like all hospitals, minimum public and staff disruption was key to this contract. Later in 2009, four McDonalds car parks were completed, followed by 14,100m2 at a Morrison’s Supermarket in Rubery (Nr Birmingham).
In 2011 the car park at Lamezia Terme airport, in Southern Italy was treated (5,125m2 ). RHiNOPHALT® has also been used on many military base parking areas, with many schemes being awarded on the success of runway and taxiway contracts.
Line removal and re-marking
RHiNOPHALT® can be used for complete covering the old lining that has been removed when having to extend the size of parking bays or re-route traffic. The preservative properties help seal and protect the aged asphalt and ensure complete coverage of the lines with a fresh black surface.
Asda, Fulwood, Lancashire UK
In 2016 Asda Superstores (part of the Walmart Group) made a decision to widen some of their parking bays from 2.4m to 2.6m, following customer feedback. Five key stores in the UK were chosen for the first sites and the largest project at 3,700m2 , was at Fulwood, near Preston, Lancashire. The location of the parking bays are in prime locations in front of the store.
The contract started on a Sunday evening which gave the contractor the most time available on site as the store is closed from 16:00. Working efficiently, they were able to combine Phases 1 and 2 into the same shift. The site had to be clear by 05:00 the following morning. The old lines were removed by water jetting and dried using a heat lance. There was no damage to the existing asphalt surface course, and only an appearance difference where the surface detritus and fines had been removed. Sealing the surface with RHiNOPHALT® will reinforce the aggregate matrix in the asphalt and prevent ravelling.
Phases 1 and 2 were treated before the lines were reapplied, as the early evening allowed for sufficient drying time. Fine RhinoDust was applied immediately after treatment to provide grip to the surface. The contractor had 2 crews on site, so with a specialist a re-lining crew, it was a quick operation towards the end of the shift.
The following weekday shifts started later after 22:00, so it became necessary to plan ahead and remove and re-apply the lines a day ahead of treatment to allow sufficient drying time before RHiNOPHALT® application. This meant that the parking bays were made available for customers the next day, causing no disruption. On the next shift, the new lines were masked before treatment application to protect them.
The night time application caused minimal disruption the client. All of the old white lines were completely removed without leaving a white trace, or ghosting, on the surface which could lead to parking confusion.
RHiNOPHALT® will seal and protect the asphalt surface of a car park, and provide an aesthetic fresh black colour that will assist with re-alignment. This colour will lighten over time as the micro-texture of the surface aggregate becomes exposed with trafficking, as the aggregate colour is lighter than the black preservative. The RHiNOPHALT® locks into the asphalt mortar and remains within the macro-texture providing a preservative seal. The night time application ensures that areas can be prepared and treated causing minimal disruption to clients and customers.
