Ralumac

Ralumac is a cold-applied asphaltic material, designed for more demanding locations on all types of surfaces. It gives a superior surface with good texture and is therefore suitable for a whole range of road maintenance problems faced by today's Road Engineer.

Ralumac's effectiveness as an overlay carpet is derived from thoroughly researched and developed Bitumen Emulsion. This is a Polymer Modified Binder which, when mixed with selected high quality aggregates and fillers, gives a material with excellent stability in summer whilst mantaining flexibility in winter.

Typical details: (0mm/8mm aggregate grading – alternative aggregate gradings are available)
Aggregate: Selected Coarse aggregates
Fine aggregate: High quality crushed aggregate
Filler: Ordinary Portland Cement
Skid resistance: Typically 65
Texture depth: Typically 1.3mm+
Marshall stability (KN): 10+
Binder content: 5% - 8% by weight
Void content: 2% - 6% by volume
Coverage rate: Will vary depending on the shape of the carriageway.

Ralupath

Ralupath is a hand applied cold asphalt resurfacing system, which provides a quick and cost effective solution to worn and distressed footways. Ralupath has been developed from the highly successful and durable Ralumac process, having all the attributes such as Polymer Modified Binder, specially selected hard wearing aggregates designed to R.M.S recipe for easy laying by hand.

Ralupath removes minor depressions and can re-profile the footway in one application. This combined with a longer contracting season gives the engineer greater programming flexibility. Ralupath is black in colour and is readily accepted by residents and the greater public giving a pleasing visual appearance.

Ralupath is a cold laid micro surface incorporating polymer modified binder.

Typical details: Aggregates 0/3mm
Aggregate: Selected high quality aggregates
Spread rate: depending on surface, traffic and conditions
Average coverage: 10/15kg per sq.metre, must be laid on a sound base

  • Cold applied
  • Visually pleasant
  • Hard wearing
  • Little disruption to traffic and pedestrians
  • Fast setting 15 – 20 mins
  • Cost effective

Failed Surface Dressing Solution

There are millions of metres of surface dressing laid on our roads each year and it is still the most economical way of holding our road surfaces together by waterproofing, giving excellent texture and wearing properties on all classes of road.

The methods of road classifications, distribution of materials, weather forecasting and productivity have improved with technology over the years but occasionally we have partial failures. Partial failures are extremely difficult to repair and can become dangerous if not attended to immediately, so the Ralumac solution is the proven method of repair.

Application process:

Ralumac is cold-applied through a specially designed continuous flow machine. Daily outputs in excess of 10,000sq. metres can be achieved with minimal disruption to traffic. Application is normally undertaken is layers with the initial regulating layer up to 30mm, followed by a uniform wearing course carpet of 8mm in thickness. The new Ralumac surface can be trafficked in 15 to 20 minutes. No rolling is required as the traffic action kneads the material, closing up the surface rendering it virtually impervious.

Fatty Surface Inhibitor

In the maintenance programme carried out each year on our roads, one of the most difficult problems facing the maintenance engineer is fatting up / excess bitumen caused by many factors and on all classes of road. The fatty problem can be seen by the black shiny areas, which develop on the surface of roads where the stone surface has been pushed into the underlying surface by the ever increasing weight and volume of heavy vehicles assisted by warm weather heating the road surface and rendering it more soft and supple. The problem is further distressed when the fatty surface is lifted on wheels / pulled and deposited further along the surface leaving small potholes and lumps or bitumen for further movement and greater distress..

Ralumac Fatty Surface Inhibitor has by its special design the ability to absorb excess bitumen into the base regulating course whilst similarly filling ruts, depressions and plucks before receiving the top / wearing coat giving an excellent riding surface with good texture.The repaired surface can be surface dressed in four weeks or left to a date in the future.

Application process:

Ralumac is cold-applied through a specially designed continuous flow machine. Daily outputs in excess of 5,000m² can be achieved with minimal disruption to traffic. Application is normally undertaken is layers with the initial regulating layer up to 60mm, followed by a uniform wearing course carpet of 8mm in thickness. The new Ralumac surface can be trafficked in 15 to 20 minutes. No rolling is required as the traffic action kneads the material, closing up the surface rendering it virtually impervious.

Edge Strengthening

Ralumac takes you back from the edge with the solution to edge distortion / depressions and can restore / reprofile up to 75mm deep ruts. The increasing assault on our highways by the growing volume and weight of modern day traffic has led to problems that are common to all classes of road – wheeltrack rutting, fretting at the edges and surface deformation.

Ralumac's designed formula with polymer modified binder, high quality aggregates and expert laying squad has proven over the past four years and 1 million square metres of edge strengthening laid to be a proven, practical and economic solution to a difficult problem.

The finished surface can be surface dressed within four weeks or left to next season. TO GET THE EDGE ON YOUR ROAD USE RALUMAC!

Rut Eliminator

Ruts are the sure sign that the ever increasing number and weight of heavy vehicles are slowly breaking down our road structures. The immediate response before the seal is broken and greater damage is caused is to fill / level / eliminate the rut.

Over the past 35 years Ralumac rut eliminator has proven in Ireland and many countries to be the tough economical solution to a major problem.

Ralumac rut eliminator is laid in two layers. The first layer / coat can take out ruts up to 75mm, if greater depths are required a second base layer can be applied followed by a wearing / top coat giving an excellent riding surface which is waterproof with great texture.

Hard Shoulder Restoration

Maintenance of hard shoulders has become an increasing problem with cable tracks and other utility trenches being cut to facilitate and enhance technology, this combined with ageing surfaces showing rutting and depressions, which hold ponding water causing surface breakdown and eventual potholing is a never ending maintenance problem.

Ralumac Hard Shoulder Restoration is the long-term maintenance solution, which regulates the ruts and depressions with its base coat taking out depths up to 75mm, following by the wearing / top coat giving an excellent riding surface with texture. The finished surface has very high rut resistance, is waterproof and can be surface dressed at any time in the future.

An extra benefit from this Ralumac design is the ability to hold back fatty areas from breaking through!
