Every instrument above feeds one system: batch records that trace each tanker load back to its raw-material intake and full lab results. If a batch does not pass, it does not ship. That traceability is what lets us put a warranty behind every delivery.

ACADEMIC & RESEARCH COLLABORATIONS
An International Hub for
Waste-Modified Asphalt Research
K2 Bitumen Sdn. Bhd. pioneers sustainable construction by transforming industrial waste into high-performance, low-carbon asphalt solutions. Our journey spans a decade, from initial R&D in 2015 with JSTI Group for Crumb Rubber Modified Bitumen (CRMB) trials to our appointment as a national blender for PETRONAS Recycled Plastic Modified Bitumen (RPMB) in 2024.
We strategically partner with leading academic and research institutions, including JSTI Group, Jabatan Kerja Raya (JKR), Road Engineering Association of Malaysia (REAM), UiTM, and JKR CREATE, to turn cutting-edge concepts into real-world infrastructure solutions.
Our robust collaboration integrates advanced material development, pavement technology research, and strict industry standards, ensuring sustainable and certified products. We actively serve as a focal point for academic study, providing opportunities for scholars to investigate the innovative use of recycled materials in enhancing road pavement properties.
Together We Build Dreams
Since its inception, K2B has established strong
partnerships with various academic and research institutions
in Malaysia and abroad. These collaborations mentioned

Abstract: Researchers are increasingly concerned about the vast amounts of waste rubber tires pro- duced globally, which contribute significantly to environmental pollution. The potential of incorporating waste rubber tires to modify bitumen has garnered considerable interest. This study assesses pavement design temperatures according to SUPERPAVE standards for representative Malaysian regions. The assessment is based on hourly air temperature data and simulates temperature diffusion in typical Malaysian road pavements using the finite difference method (FDM). Tests on neat bitumen (PEN 60/70) and crumb rubber- modified bitumen (CR-TMB) samples evaluated their physical and rheological properties across various temperatures and aging stages. These tests were conducted using the dynamic shear rheometer, rotational viscometer, and bending beam rheometer.

Exploring The Effectiveness of Crumb Rubber Modified Asphalt (CRMA): A Comprehensive Overview On Submerged Roads In Malaysia

Abstract: As Malaysia is located within the equatorial region, heavy rainfalls and thunderstorms are common occurrences, often leading to flooding that affects the extensive road network in the East Coast of the Malaysian Peninsular. Some flooding involves stagnant water that may remain for several days before subsiding. The impact of moisture on the pavement surface is extensively documented with damages often includes stripping of the asphalt due to the compromised properties of the bitumen. This study aims to evaluate the effectiveness of the “special mix” bitumen known as Crumb Rubber Modified Bitumen, CRMB, as a replacement for the existing bitumen grade against moisture induced damages. Test samples were collected from flooded affected areas namely Federal Road FT 02 Sec 321, Sec 331 and FT 62 Sec 0 with two of the areas flooded twice within the same year. Core samples from FT 222, Sec 0, using conventional bitumen, were also tested as a control sample. The roads were maintained using two methods, Mill & Pave (MP) 50mm and Overlay 50mm. Maintenance work was conducted in different years to ensure a more comprehensive analysis. The moisture susceptibility test (AASHTO T283) was used to compare the performance of CRMB against conventional bitumen.
The findings indicate that the CRMA with Mill and Pave 50mm (Section 331) shows the highest moisture re- sistance with a TSR % of 92.6%, making it the most effective for flood-prone areas. In contrast, the CRMA overlay and AC 14 with Mill & Pave 50mm treatments perform poorly, with TSR % values of 45.4% and 45.2%, respectively. This highlights the benefits of CRMB in enhancing road durability in areas prone to heavy rainfall and flooding. This improvement is critical for enhancing the longevity and safety of road networks in such regions, potentially leading to reduced maintenance costs and disruptions.
