Performance of ICP

Laying Pattern of ICP

  • Traffic area : herringbone bond
  • Pedestrian and light traffic area : stretcher bond
  • Non traffic : basket weave

Performance of ICP

Case study: Jalan Connaught Underpass (DBKL)

  • Road Pavement Material

Previously: Asphalt Currently: ICP

  • Issue: Rutting and stripping of asphalt leads to potholes

due to heavy traffic and overflow water from above highway further weakens the asphalt material over the

  • time. Repetitive repair works are required.
  • Solution: Replace asphalt with ICP, tremendously reduced

the frequency of pothole maintenance.

slide-14
SLIDE 14

Performance of ICP

Case study: Jalan Bukit Angin (Temerloh)

  • Road Pavement Material

Previously: Asphalt Currently: ICP

  • Issue: Rutting and stripping of asphalt due to tyre

forces pushing the asphalt thus, weakens the pavement and requires repetitive patching works.

  • Solution: Replace asphalt with ICP, reduce the

frequency of patching up maintenance and have lesser rutting issue.

slide-15
SLIDE 15

Performance of ICP

Case study: Westport & Pelabuhan Tanjung Pelepas (PTP)

  • Road Pavement Material

Previously: Asphalt/ Concrete Currently: ICP

  • Issue: Rutting of asphalt and potholes due to daily

heavy traffic (min. 20 tonnes cargo) or concrete slab need days to be repaired before can be re-opened for traffic. Repetitive repair works are required.

  • Solution: Replaced with ICP, reduces the

frequency resurfacing and can open to traffic immediately, thus reduce maintenance cost and time loss.

slide-16
SLIDE 16

Performance of ICP

Case study: Jalan Maran – Temerloh

  • Road Pavement Material

Previously: Asphalt Currently: ICP

  • Issue: Vehicles not slowing down when

approaching school zone area (30km/h). Speed hump not allowed on federal roads and is in front

  • f a school. Road heading towards the school is

downhill, add speed to the vehicles.

  • Solution: Replace asphalt with ICP, reduce the

frequency of pothole patching and resurfacing. Also helps in reducing vehicle speed by up to 10km/h, approaching school zone.

slide-17
SLIDE 17

Performance of ICP

Case study: Subang Jaya

  • Road Pavement Material

Previously: Asphalt Currently: ICP

  • Issue: Rutting of asphalt and potholes due to

daily heavy traffic shorten the lifespan of the

  • asphalt. Requires resurfacing frequently.
  • Solution: Replace asphalt with ICP, reduce the

frequency of pothole patching and resurfacing leads to cost saving.

Permeable ICP Properties

Fine Finish (Porosity 10 to 12%) (150Ltrs/m2/min) Rough Finish (Porosity 15 to 17%) (300Ltrs/m2/min)

Performance of Permeable ICP

Case study: Hospital Kuala Lumpur (HKL)

  • Pavement Material

Previously: Concrete (before 2012) Currently: ICP (since 2012)

  • Issue: Water ponding later water basin during heavy

rain as surface runoff from Jalan Masjid & Jalan Utama Hospital flowed into this area (lower).

  • Solution: Redo the ground with subsoil pipe and laid

with Permeable ICP, no more water basin since then.

SLIDE 21

Performance of Permeable ICP

Case study: Monash University Malaysia Campus

  • Pavement Material

Previously: Asphalt (before 2018) Currently: ICP (since 2018)

  • Issue: Water ponding at the staff parking area

during heavy rain.

  • Solution: Redo the ground with subsoil pipe

and laid with Permeable ICP and grass ICP, no more water ponding issue since then and added improved the landscape.

Performance of Permeable ICP

Case study: Paradigm Mall JB

  • Pavement Material

Proposed: Concrete cover Adopted: Permeable ICP

  • Issue: Product that can act as drain cover and allow

water to flow through, blend in with surrounding pavement, and doesn’t pose hazard/risk to visitor walking over.

  • Solution: Permeable ICP, blend with the surrounding

pavement design and doesn’t have huge gaps.

Road Marking & Delineation ICP

  • Add aesthetic to the pavement
  • Glass beads is mixed with the concrete, will not scrape easily

from its layer of 10mm thick

  • ICP compressive strength of 30 or 45 MPa
  • Reflective Index = 100mcd/m2/lx

Durability Test of ICP

Compressive Strength

  • Is to determine how much load an ICP can withstand.

𝐷 = 𝑋 𝐵 × 5 𝐵 𝐼 + 1.87

C = Compressive strength (MPa) W = Total load specimen fails (N) A = Gross plan area (mm2) H = Height of specimen (mm)
