Features & Advantages of Shelmac PR

Features of Shelmac PR Features of Shelmac PR
  • Increased convenience and reduced cost of maintenance.
  • Ready for immediate use with pre-mixed aggregates (cold technology)
  • No heating or mixing or additions to the product before or after application
  • Requires simple equipments such as hand brushes, shovel and a rammer. The use of roller is not necessary
  • No pretreatment of repair areas is required i.e cuttingout, Use of tack coat
  • Instant curing / setting partly by air-drying and partly by compaction
  • All-weather usage product. Instant repair od roads with Shelmac PR can be made in monsoons & wet conditions, extremes of heat (60° C+) and cold conditions.
Advantages & Benefits of Shelmac PR
  • Eliminates necessity of plant & machinery at site
  • Very fast setting as compared to other options
  • After repari, the road can be immediately opened to heavy traffic reducing the traffic hold up time.
  • No sticking/picking-up of material by vehicle tyres
  • Highly stable at high pavement temperatures
  • Highly resistant to stripping by water
  • Offers high skid resistance
  • Leads to no ravelling, no bleeding, no depression / permanent deformation
  • No wastage of material
  • Minimum unskilled labour required
  • Long service life of the repaired potholes
  • No pollution during maintenance

How to use Shelmac PR


  • Comes in convenient ready to use packing of 50kg net HDPE bags with inside LDPE liner
  • Preparation prior to reapir is minimal. For optimum results, remove standing water/loose debris/dust with a brush from the pothole. However, where this proved impossible, repairs have always remained in excellent condition
  • Pour Shelmac PR directly from the bag into the pothole and overfill by 10mm
  • Where deep potholes are to be repaired, it is economical to first compact approximately 10mm shelmac PR across bottom of pothole, then fill remaining cavity with 6/10 mm metal chips well compacted and then top with 25mm of shelmac PR as a final course
  • compaction can be done using a simple hand rammer. for large repairs, using a roller shall ensure smooth/even compaction. Do not use plate compactor
  • Cures instantly and compacts further with traffic
  • Open to traffic immediately since it does not stick to tyres

Cost Effectiveness

  • Use of Shelmac PR results in improving the efficiency and effectiveness resulting in substantial cost savings and convenience as compared to conventional methods.
  • In making cost comparison between Shelmac PR and the conventional hot and cold patch reapir materials, it would not be wise to simply compare preice per tonne.
  • It is necessary to make an overall comparison taking into account the equipment involved, wasage of material, man hours, traffic hold-ups and most importantly, the durability of repairs. Only then can accurate cost assesment be reached.
  • Shelmac PR uses very simple application tools and enables instant repairs of potholes as soon as pothole is observed thereby reducing the response time and preventing further deterioration of the road/pothole.
